Shaft sinking. Shaft mining or shaft sinking is the action of excavating a mine shaft from the top down, where there is initially no access to the bottom. Shallow shafts, typically sunk for civil engineering projects, differ greatly in execution method from deep shafts, typically sunk for mining projects.Shaft sinking is one of the most difficult of all mine development methods: restricted space, gravity, groundwater and specialized procedures make the task quite formidable. Shafts may be sunk by conventional drill and blast or mechanised means.Historically, mine shaft sinking has been among the most dangerous of all the mining occupations and the preserve.

Shaft sinking. of mining contractors called sinkers. Today shaft sinking contractors are concentrated in Canada, Germany, China and South Africa.The modern shaft sinking industry is gradually shifting further towards greater mechanisation, recent innovations in the form of full-face shaft boring (akin to a vertical tunnel boring machine) have shown promise but the use of this method is, as of 2019, not widespread.## Mine shafts.Mine shafts are vertical or near-vertical tunnels, which are "sunk" as a means of accessing an underground ore body, during of the development of an underground mine.The shape (in plan view), dimensions and depth of mine shafts vary greatly.

Shaft sinking. in response to the specific needs of the mine they are part of and the geology they are sunk through. For example, in North and South America, smaller shafts are designed to be rectangular in plan view with timber supports. Larger shafts are round in plan and are concrete lined.Mine shafts may be used for a variety of purposes, including as a means of escape in the event of an emergency underground and allowing for the movement of: People Materials Mine services (such as compressed air, water, backfill, power, communications and fuel) Ventilation air Broken rock (in the form of.

Shaft sinking. payable ore, or non payable waste) Or any combination of the aboveWhen the top of the excavation is the ground surface, it is referred to as a "shaft"; when the top of the excavation is underground, it is called a "winze" or a "sub-shaft". Small shafts may be excavated upwards from within an existing mine as long as there is access at the bottom, in which case they are called "raises".A shaft may be either vertical or inclined (between 80 and 90 degrees to the horizontal), although most modern mine shafts are vertical. If access exists at the bottom of.

Shaft sinking. the proposed shaft, and ground conditions allow, then raise boring may be used to excavate the shaft from the bottom up; such shafts are called "borehole shafts".Following the Hartley Colliery disaster where the single shaft at the mine became blocked, the United Kingdom made single shaft mines illegal in 1862, establishing the practice that all underground mines must have a "a second means of egress". Many other global mining jurisdictions have adopted this rule and shafts are therefore often found in pairs (although there are multiple alternative methods of providing a second means of egress).The current the deepest single lift.

Shaft sinking. (i.e. continuous) mine shaft in the world is the 2991m deep, main shaft at South Deep Mine in South Africa, owned by Gold Fields Limited, which, along with its twin ventilation shafts, took ten years to sink and equip.## Parts of a mine shaft.The most visible feature of a traditionally-built mine shaft is the headframe (or winding tower, poppet head or pit head) which stands above the shaft. Depending on the type of hoist (or winder) used, the top of the headframe will either house a hoist motor or a sheave wheel (with the hoist motor mounted on the ground).

Shaft sinking. The headframe will also typically contain bins for storing ore being transferred to the processing facility.At ground level beneath and around the headframe is the Shaft Collar (also called the Bank or Deck), which provides the foundation necessary to support the weight of the headframe and provides a means for workers, materials and services to enter and exit the shaft. Collars are usually massive reinforced concrete structures with more than one level. If the shaft is used for mine ventilation, a plenum space or casing is incorporated into the collar to ensure the proper flow of air into and out.

Shaft sinking. of the mine.Beneath the collar the part of the shaft which continues into the ground is called the "shaft barrel".At locations where the shaft barrel meets horizontal workings there is a "shaft station" (or inset) which allows men, materials and services to enter and exit the shaft. From the station tunnels (drifts, galleries or levels) extend towards the ore body, sometimes for many kilometers. The lowest shaft station is most often the point where rock leaves the mine levels and is transferred to the shaft, if so a "loading pocket" is excavated on one side of the shaft at this.

Shaft sinking. location to allow transfer facilities to be built.Beneath the lowest shaft station the shaft continues on for some distance, this area is referred to as the "shaft bottom". A tunnel called a "ramp" typically connects the bottom of the shaft with the rest of the mine, this ramp often contains the mine's water handling facility, called the "sump", as water will naturally flow to the lowest point in the mine.## Shaft lining.Many (although not all) shafts are lined following excavation and the installation of temporary ground support.The shaft lining performs several functions; it is first and foremost a safety feature.

Shaft sinking. preventing loose or unstable rock from falling into the shaft, then a place for shaft sets to bolt into, and lastly a smooth surface to minimise resistance to airflow for ventilation.Final choice of shaft lining is dependent on the geology of the rock which the shaft passes through, some shafts have several liners sections as required Where shafts are sunk in very competent rock there may be no requirement for lining at all, or just the installation of welded mesh and rock bolts. The material of choice for shaft lining is mass concrete which is poured behind "shaft forms" in.

Shaft sinking. lifts of 6 m as the shaft advances (gets deeper).Shotcrete, fibrecrete, brick, cast iron tubing, and precast concrete segments have all been used at one time or another. Additionally, the use of materials like bitumen and even squash balls have been required by specific circumstances. In extreme cases, particularly when sinking through halite, composite liners consisting of two or more materials may be required.The shaft liner does not reach right to the bottom of the shaft during sinking, but lags behind by a fixed distance. This distance is determined by the methodology of excavation and the design thickness of the.

Shaft sinking. permanent liner. To ensure the safety of persons working on the shaft bottom temporary ground support is installed, usually consisting of welded mesh and rock bolts. The installation of the temporary ground support (called "bolting") is among the most physically challenging parts of the shaft sinking cycle as bolts must be installed using pneumatic powered rock drills.For this reason, and to minimise the number of persons on the shaft bottom a number of projects have successfully switched to shotcrete for this temporary lining. Research and development in this area is focusing on the robotic application of shotcrete and the commercialisation.

Shaft sinking. of thin sprayed polymer liners.## Shaft compartments.Where the shaft is to be used for hoisting it is frequently split into multiple compartments by "shaft sets", these may be made of either timber or steel. Vertical members in a shaft set are called "guides", horizontal members are called "buntons". For steel shaft guides, the main two options are hollow structural sections and top hat sections. Top hat sections offer a number of advantages over hollow structural sections including simpler installation, improved corrosion resistance and increased stiffness. Mine conveyances run on the guides in a similar way to how a steel roller.

Shaft sinking. coaster runs on its rails, both having wheels which keep them securely in place.Some shafts do not use guide beams but instead utilize steel wire rope (called "guide rope") kept in tension by massive weights at shaft bottom called "cheese weights" (because of their resemblance to a truckle or wheel of cheese) as these are easier to maintain and replace.The largest compartment is typically used for the "mine cage", a conveyance used for moving workers and supplies below the surface, which is suspended from the hoist on steel wire rope. It functions in a similar manner to an elevator. Cages.

Shaft sinking. may be single-, double-, or rarely triple-deck, always having multiple redundant safety systems in case of unexpected failure.The second compartment is used for one or more skips, used to hoist ore to the surface. Smaller mining operations use a skip mounted underneath the cage, rather than a separate device, while some large mines have separate shafts for the cage and skips. The third compartment is used for an emergency exit; it may house an auxiliary cage or a system of ladders. An additional compartment houses mine services such as high voltage cables and pipes for transfer of water, compressed air.

Shaft sinking. or diesel fuel.A second reason to divide the shaft is for ventilation. One or more of the compartments discussed above may be used for air intake, while others may be used for exhaust. Where this is the case a steel or concrete wall called a "brattice" is installed between the two compartments to separate the air flow. At many mines there are one or more complete additional separate "auxiliary shafts" with separate head gear and cages.## Shaft construction.The lowest point in a sinking shaft is known as "shaft bottom", shaft projects differ from some other forms of mine development in.

Shaft sinking. that all activities that take place on shaft bottom become part of the critical path for the project schedule. The infrastructure required to sink a shaft is referred to a "the sinking set-up".It is typical for progress (the "sinking rate") in the sinking phase (that is excavation, ground support and lining) of a shaft project to follow a learning curve as the project team repeat the same series of activities over and over in what is called "the sinking cycle", eventually approaching the theoretical maximum rate for that sinking set up over time. The use of experienced shaft sinkers is.

Shaft sinking. necessary to reduce the length of this learning curve and thus the duration of the project as much as possible.Key to a successful shaft sinking project are: Getting the various components of the sinking set-up correct and installed at the right time. Having experienced people involved from as early in the project as possible Using the available time on shaft bottom as efficiently as possible.Although significant emphasis is placed on the rate of progress of a project sinking cycle by shaft sinkers, sinking is only one of a number of phases in the conventional construction of a new shaft, as.

Shaft sinking. follows; "Box Cut Excavation". A box cut is a large square or rectangular excavation typically completed using earthmoving equipment down to bedrock, inside which the shaft collar will be constructed. Having the loads imposed by the collar, headframe and hoisting plant transferred into solid rock is necessary to prevent unplanned subsidence. Where the depth of bedrock is to great to for a box cut to economically viable, or the bedrock is not strong enough, civil engineering techniques such as diaphragm walls or concrete piles may be used to create a deep foundation instead. "Pre-Sink". The pre-sink is the excavation and.

Shaft sinking. support of the first 60 – 100 meters of the shaft barrel, often completed smaller equipment such as handheld, pneumatic drilling equipment to drill holes for basting and ground support and mini-excavators for mucking. During the pre-sink hoisting of muck and equipment is usually performed by a mobile crane on surface. It is necessary to sink this part of the shaft first so that the Galloway, a multi-level working platform may be installed with enough vertical distance to shaft bottom that it will not be damaged by fly rock during blasting. "Collar Construction". From the bottom of the box-cut, the.

Shaft sinking. shaft collar is constructed bottom up in a planned series of concrete pours. "Galloway (Sinking Stage) Construction & Installation." The Galloway (also known as a Sinking Stage or Scaffold) is a multi-level working platform, suspended in the shaft from winches located on surface. The Galloway allows sinkers to efficiently work on differing levels as required by the various tasks of the sinking cycle. It is typical for the Galloway to be constructed off to one side of the shaft and lowered into the pre-sink with a crane in as complete a state as possible. Once in place the Galloway is.

Shaft sinking. "chaired" (suspended from the shaft collar) while the headframe is built above, often protected by a bulkhead. "Headframe & Hoist House Construction." With the collar constructed and the Galloway installed the headframe and hoist (or winder) houses may be constructed and the hoist and winch ropes installed. Headframes may be either steel or concrete and their design will determine how they are constructed. The Galloway is moved in the shaft by means of winches, which move slowly and are rated for significant loads, while the sinking buckets (or kibbles) are moved in the shaft by the sinking hoist, which moves.

Shaft sinking. quickly and is rates for less load that the winches. To protect the hoist(s) and winches and the sensitive electronics which are used to control their operation they are normally installed inside of a build called a hoist (or winder) house. "Commissioning Sinking Set Up." The Sinking set-up must then be commissioned to ensure that all parts are operating as planned. "Full Sink". The activities of the sinking cycle (excavation, installation of temporary ground support, placement of the shaft lining and extending shaft services) all take place in this phase of construction. In a shaft where there are to be.

Shaft sinking. multiple working levels, shaft stations and station stubs (short lengths of horizontal tunnel leading away from the station) will be developed by the sinkers on the way down. As the equipment to excavate these stations must be small enough to fit through the openings in the Galloway, the rate of advance in developing the station stubs is typically low, compared to what can be achieved with full size mining equipment so station stubs are typically kept as short as possible. "Shaft Equipping & Headframe Changeover." Once the shaft reaches the final design depth, the shaft is stripped of any temporary.

Shaft sinking. services, the Galloway cut up or modified to suit the installation of the permanent shaft set-up, the shaft sets (if required) installed and the headframe / winders modified to allow for permanent hoisting. Any permanent conveyances will be installed at this stage. "Commissioning Permanent Set Up." The Permanent set-up must then be commissioned to ensure that all parts are operating as planned before being handed over to the new owner.As with the depth and design of shafts significant variations do exist in this sequence depending on local conditions, for example in that hard Canadian Shield rocks which dominate shaft sinking.

Shaft sinking. in Canada a deep and complex shaft collar is unnecessary as the bedrock is both strong and close to surface. This reduces the amount of time typically required to establish the shaft collar.Traditionally sinking contractors would build a temporary headframe for the sinking set up, which would then be dismantled to make way for a permanent headframe. With the growth in complexity and duration of shaft sinking projects over time it has become more common to incorporate more of the permanent shaft set-up into the sinking phase. This results in a reduced overall project duration, as for example, if the.

Shaft sinking. service piping used to sink the shaft does not need to be stripped out to make way for permanent piping.With the advancements made in raise boring technology, raise borers have been used to create a pilot hole for shaft sinking, where access exists at the bottom of the new shaft, in this case the sinking phase is dedicated to enlarging this pilot hole to full diameter (a process usually called "slashing"). This methodology can be considerably faster than full face sinking as muck (waste rock) from sinking falls down the pilot hole and is handled using existing mine infrastructure off.

Hedgehog. belly, which are not quilled. Since the effectiveness of this strategy depends on the number of spines, some desert hedgehogs that evolved to carry less weight are more likely to flee or attack, ramming an intruder with the spines; rolling into a spiny ball for those species is a last resort. Hedgehogs are primarily nocturnal, though some species can also be active during the day. Hedgehogs sleep for a large portion of the day under bushes, grasses, rocks, or most commonly in dens dug in the ground, with varying habits among the species. All wild hedgehogs can hibernate, though not.

Securigera varia. Securigera varia (synonym Coronilla varia), commonly known as crownvetch or purple crown vetch, is a low-growing legume vine. It is native to Africa, Asia and Europe and is commonly used throughout the United States and Canada for erosion control, roadside planting and soil rehabilitation. It has become an invasive species in many states of the US.Crownvetch grows 1 to 2 feet tall and bears small clusters of 1/2-inch pink and white flowers from early summer to late fall. The variety Penngift produces mounds of pink flowers. Crownvetch is a tough, aggressive spreading plant that will crowd out its neighbors in.

Marble Church, Bodelwyddan. St Margaret's Church (nicknamed The Marble Church), Bodelwyddan, is a Decorated Gothic Style parish church in the lower Vale of Clwyd in Denbighshire, Wales and is visible for many miles because its spire rises to 202 feet. It lies just off the A55 trunk road.The church was erected by Lady Margaret Willoughby de Broke (daughter of Sir John Williams of nearby Bodelwyddan Castle) in memory of her husband, Henry Peyto-Verney, 16th Baron Willoughby de Broke. She laid the foundation stone on 24 July 1856 and the new church designed by John Gibson was consecrated by the Bishop of St Asaph.

Bursaria spinosa. Bursaria spinosa is a small tree or shrub in the family Pittosporaceae. The species occurs mainly in the eastern and southern half of Australia and not in Western Australia and the Northern Territory. Reaching 10 m (35 ft) high, it bears fragrant white flowers at any time of year but particularly in summer. A common understorey shrub of eucalyptus woodland, it colonises disturbed areas and fallow farmland. It is an important food plant for several species of butterflies and moths, particularly those of the genus "Paralucia", and native bees.## Description."Bursaria spinosa" has a variable habit, and can grow anywhere from.

Bursaria spinosa. first formally described by Antonio José Cavanilles in 1797 in his book, "Icones et Descriptiones Plantarum". It is known by many common names, including Australian blackthorn, blackthorn, Christmas bush, mock orange, native blackthorn, native box, native olive, prickly box, prickly pine, spiny box, spiny bursaria, sweet bursaria, thorn box and whitethorn. Summer flowering has given rise to the name (Tasmanian) Christmas bush in Tasmania and South Australia (not to be confused with "Prostanthera lasianthos"). Indigenous names recorded include "kurwan" in Coranderrk, Victoria, and "geapga" from Lake Hindmarsh Station."Bursaria spinosa" is highly variable in appearance and habit, as are other species.

Infrequent winter service provided by underpowered steamships incapable of breaking sea ice ensured the survival of a passenger and mail service across Abegweit Passage using iceboats until a permanent ferry service was established in the 1910s.The unsatisfactory winter steamship service and reliance upon primitive iceboats provoked complaints from the Island government until the federal government decided to implement a railcar ferry service across Abegweit Passage between new ports at Port Borden and Cape Tormentine.In 1912, the federal government promised to open a car ferry between the "Capes" (Cape Traverse, PEI to Cape.

The privately owned New Brunswick and Prince Edward Island Railway from Sackville, New Brunswick to Cape Tormentine was purchased by the federal government and an order was made with a shipyard in England for an icebreaking railcar ferry, to be called the "Prince Edward Island". Ports were developed at Carleton Point, several kilometres west of Cape Traverse, and the existing harbour at Cape Tormentine; the new port at Carleton Point would be named Borden in honour of Prime Minister Sir Robert Borden.The new ferry entered service in 1915 and operated on the former steamship routes until port facilities.

The Amherst Head staging facility was where all large components were built, including the pier bases, ice shields, main spans, and drop-in spans. The Bayfield facility was used to construct components for the near-shore bridges which were linked using a launching truss extending over shallow waters almost 2 (km) from the New Brunswick shore, and .5 (km) from the Prince Edward Island.

In separate construction, the federal and provincial governments built a new commercial and tourist development on the abandoned CN rail yards in Borden-Carleton, with phase I of this facility opening in spring 1997 as "Gateway Village". New Brunswick has never received similar federal support to improve the economy of Cape Tormentine, which has become a shadow of its former role in PEI transportation history, although in recent years a new eco-tourist and visitor centre.

Osmunda regalis. Osmunda regalis, or royal fern, is a species of deciduous fern, native to Europe, Africa and Asia, growing in woodland bogs and on the banks of streams. The species is sometimes known as flowering fern due to the appearance of its fertile fronds.## Names.The name "Osmunda" possibly derives from "Osmunder", a Saxon name for the god Thor. The name "royal fern" derives from its being one of the largest and most imposing European ferns. The name has been qualified as "old world royal fern" in some American literature to distinguish it from the closely related American royal fern, "O. spectabilis".

Osmunda regalis. However this terminology is not found in British literature.## Description."Osmunda regalis" produces separate fertile and sterile fronds. The sterile fronds are spreading, 60 - 160 (cm) tall and 30 - 40 (cm) broad, bipinnate, with 7-9 pairs of pinnae up to 30 (cm) long, each pinna with 7-13 pairs of pinnules 2.5-6.5 cm long and 1–2 cm broad. The fertile fronds are erect and shorter, 20–50 cm tall, usually with 2-3 pairs of sterile pinnae at the base, and 7-14 pairs of fertile pinnae above bearing the densely clustered sporangia.In many areas, "O. regalis" has become rare as a result.

Osmunda regalis. of wetland drainage for agriculture.## Evolution.The oldest known fossils of "Osmunda" date to the Paleocene, "Osmunda" likely derives from fossil species currently assigned to "Claytosmunda".## Varieties.There are three to four varieties as traditionally construed:"Osmunda regalis" var. "regalis". Europe, Africa, southwest Asia. Sterile fronds to 160 cm tall."Osmunda regalis" var. "panigrahiana" R.D.Dixit. Southern Asia (India)."Osmunda regalis" var. "brasiliensis" (Hook. & Grev.) Pic. Serm. Tropical regions of Central and South America; treated as a synonym of var. "spectabilis" by some authors."Osmunda regalis" var. "spectabilis" (Willdenow) A.Gray. Eastern North America. Sterile fronds to 100 cm tall. Now accepted as a separate species, "Osmunda.

Osmunda regalis. spectabilis".## Similar species.There are three very similar species, "Osmunda spectabilis", "Osmunda lancea" and "Osmunda japonica". Recent genetic analysis (Metzgar et al., 2008) has shown that the New World varieties are in a clade that is sister to the Old World varieties of "Osmunda regalis". If this is true, then "O. lancea" and "O. japonica" should either be regarded as varieties of "O. regalis", or, conversely, "O. regalis var. spectabilis" should be regarded as a separate species, "Osmunda spectabilis" Willdenow. The var. "brasiliensis" would then be "Osmunda spectabilis" Willdenow var. "brasiliensis" Hooker & Greville.## Cultivation."Osmunda regalis" is widely cultivated in temperate.

Osmunda regalis. regions. The species and the cultivar 'Cristata' have both gained the Royal Horticultural Society's Award of Garden Merit. Osmunda plants should be planted in preferably acidic, moist soil, associating well with other large moisture-loving plants such as "Rodgersia" and "Gunnera". However, it tolerates a range of soil and climatic conditions.## Other uses.The roots, along with those of other species of "Osmunda", are used for the production of osmunda fibre, used as a growing medium for cultivated orchids and other epiphytic plants.According to Slavic mythology, the sporangia, called "Perun's flowers", have assorted magical powers, such as giving their holders the ability.

Osmunda regalis. to defeat demons, fulfill wishes, unlock secrets, and understand the language of trees. However, collecting the sporangia is a difficult and frightening process. In earlier traditions, they must be collected on Kupala night; later, after the arrival of Christianity, the date is changed to Easter eve. Either way, the person wanting to collect Perun's flowers must stand within a circle drawn around the plant and withstand the taunting or threats of demons.The young shoots of the fern are, along with the similar shoots of many other fern species, known in some places as fiddleheads, and eaten as food, thought to.

Tetrahedron. of a tetrahedron the base is a triangle (any of the four faces can be considered the base), so a tetrahedron is also known as a "triangular pyramid".Like all convex polyhedra, a tetrahedron can be folded from a single sheet of paper. It has two such nets.For any tetrahedron there exists a sphere (called the circumsphere) on which all four vertices lie, and another sphere (the insphere) tangent to the tetrahedron's faces.## Regular tetrahedron.A regular tetrahedron is a tetrahedron in which all four faces are equilateral triangles. It is one of the five regular Platonic solids, which have been known.

Tetrahedron. edge of the base. This follows from the fact that the medians of a triangle intersect at its centroid, and this point divides each of them in two segments, one of which is twice as long as the other (see ).For a regular tetrahedron with side length "a", radius "R" of its circumscribing sphere, and distances "di" from an arbitrary point in 3-space to its four vertices, we haveformula_7## Isometries of the regular tetrahedron.The vertices of a cube can be grouped into two groups of four, each forming a regular tetrahedron (see above, and also , showing one of the.

Other names for the same shape include bisphenoid, isosceles tetrahedron and equifacial tetrahedron.## Orthoschemes.A 3-orthoscheme is a tetrahedron where all four faces are right triangles. An orthoscheme is an irregular simplex that is the convex hull of a tree in which all edges are mutually perpendicular. In a 3-dimensional orthoscheme, the tree consists of three perpendicular edges connecting all four vertices in a linear path that makes two right-angled turns. The 3-orthoscheme is a tetrahedron having two.

Tetrahedron. its characteristic tetrahedron by its planes of symmetry.If the tetrahedron has edge length 2, its characteristic tetrahedron's six edges have lengths , , (the exterior right triangle face, the "characteristic triangle" of the tetrahedron), plus , , (edges that are the "characteristic radii" of the tetrahedron). The 3-edge path along orthogonal edges of the orthoscheme is , , , first from a tetrahedron vertex to an tetrahedron edge center, then turning 90° to an tetrahedron face center, then turning 90° to the tetrahedron center. The orthoscheme has four dissimilar right triangle faces. The exterior face is a 30-60-90 triangle which.

The cube can be dissected into six 3-orthoschemes, three left-handed and three right-handed (one of each at each cube face), and cubes can fill space, so the characteristic 3-orthoscheme of the cube is a space-filling tetrahedron in this sense.

Then another volume formula is given byformula_25## Properties analogous to those of a triangle.The tetrahedron has many properties analogous to those of a triangle, including an insphere, circumsphere, medial tetrahedron, and exspheres. It has respective centers such as incenter, circumcenter, excenters, Spieker center and points such as a centroid. However, there is generally no orthocenter in the sense of intersecting altitudes.Gaspard Monge found a center that exists in every tetrahedron, now known as the Monge point: the point where the six midplanes of a tetrahedron intersect. A midplane is defined as a plane that is orthogonal to.

Tetrahedron. segment joining the midpoints of two opposite edges is called a "bimedian" of the tetrahedron. Hence there are four medians and three bimedians in a tetrahedron. These seven line segments are all concurrent at a point called the "centroid" of the tetrahedron. In addition the four medians are divided in a 3:1 ratio by the centroid (see Commandino's theorem). The centroid of a tetrahedron is the midpoint between its Monge point and circumcenter. These points define the "Euler line" of the tetrahedron that is analogous to the Euler line of a triangle.The nine-point circle of the general triangle has an.

Lorenz Lindelöf found that, corresponding to any given tetrahedron is a point now known as an isogonic center, "O", at which the solid angles subtended by the faces are equal, having a common.

What condition on 12 angles is necessary and sufficient for.

Tetrahedron. them to be the 12 angles of some tetrahedron? Clearly the sum of the angles of any side of the tetrahedron must be 180°. Since there are four such triangles, there are four such constraints on sums of angles, and the number of degrees of freedom is thereby reduced from 12 to 8. The four relations given by this sine law further reduce the number of degrees of freedom, from 8 down to not 4 but 5, since the fourth constraint is not independent of the first three. Thus the space of all shapes of tetrahedra is 5-dimensional.## Law of.

Osprey. The osprey (Pandion haliaetus), also called sea hawk, river hawk, and fish hawk, is a diurnal, fish-eating bird of prey with a cosmopolitan range. It is a large raptor reaching more than 60 (cm) in length and 180 (cm) across the wings. It is brown on the upperparts and predominantly greyish on the head and underparts.The osprey tolerates a wide variety of habitats, nesting in any location near a body of water providing an adequate food supply. It is found on all continents except Antarctica, although in South America it occurs only as a non-breeding migrant.As its other common names.

Osprey. suggest, the osprey's diet consists almost exclusively of fish. It possesses specialised physical characteristics and exhibits unique behaviour to assist in hunting and catching prey. As a result of these unique characteristics, it has been given its own taxonomic genus, "Pandion", and family, Pandionidae.## Taxonomy.The osprey was described by Carl Linnaeus under the name "Falco haliaeetus" in his landmark 1758 10th edition of "Systema Naturae". The genus, "Pandion", is the sole member of the family Pandionidae, and used to contain only one species, the osprey ("P. haliaetus"). The genus "Pandion" was described by the French zoologist Marie Jules César Savigny.

Osprey. in 1809. It has always presented something of a riddle to taxonomists, but here it is treated as the sole living member of the family Pandionidae, and the family listed in its traditional place as part of the order Falconiformes.Other schemes place it alongside the hawks and eagles in the family Accipitridae—which itself can be regarded as making up the bulk of the order Accipitriformes or else be lumped with the Falconidae into Falconiformes. The Sibley-Ahlquist taxonomy has placed it together with the other diurnal raptors in a greatly enlarged Ciconiiformes, but this results in an unnatural paraphyletic classification.The osprey.

Osprey. is unusual in that it is a single living species that occurs nearly worldwide. Even the few subspecies are not unequivocally separable. There are four generally recognised subspecies, although differences are small, and ITIS lists only the first two. "Pandion haliaetus haliaetus" – : the nominate subspecies, occurring in the Palearctic realm. "P. haliaetus carolinensis" – : mainland Americas. This form is larger, darker bodied and has a paler breast than the type of the first description. "P. haliaetus ridgwayi" – : Caribbean islands. This form has a very pale head and breast compared with nominate "haliaetus", with only a.

"P. haliaetus cristatus" – : coastline and some large rivers of Australia and Tasmania. The smallest and most distinctive subspecies, also non-migratory. Some authorities have assigned it full species status as "Pandion cristatus", known as the eastern osprey.## Fossil record.To date there have been two extinct species named from the fossil record. "Pandion homalopteron" was named by Stuart L. Warter in 1976 from fossils of Middle Miocene, Barstovian age, found in marine deposits in the southern part of California. The second named species "Pandion lovensis", was.

Osprey. described in 1985 by Jonathan J. Becker from fossils found in Florida and dating to the latest Clarendonian and possibly representing a separate lineage from that of "P. homalopteron" and "P. haliaetus". A number of claw fossils have been recovered from Pliocene and Pleistocene sediments in Florida and South Carolina.The oldest recognized family Pandionidae fossils have been recovered from the Oligocene age Jebel Qatrani Formation, of Faiyum, Egypt. However they are not complete enough to assign to a specific genus. Another Pandionidae claw fossil was recovered from Early Oligocene deposits in the Mainz basin, Germany, and was described in 2006.

Osprey. by Gerald Mayr.## Etymology.The genus name "Pandion" derives from "Pandíōn" , the mythical Greek king of Athens and grandfather of Theseus, Pandion II. Although Pandion II was not used to name a bird of prey, Nisus, a king of Megara, was used for the genus. The species name "haliaetus" () comes from Greek "haliáetos" "sea-eagle" (also "haliaietos") from the combining form "hali-" of "hals" "sea" and "aetos", "eagle".The origins of "osprey" are obscure; the word itself was first recorded around 1460, derived via the Anglo-French "ospriet" and the Medieval Latin "avis prede" "bird of prey," from the Latin "avis praedae.

Even larger 2.8 (kg) northern pike ("Esox lucius") has been taken in Russia.Ospreys have vision that is well adapted to detecting underwater objects from the air. Prey is first sighted when the osprey is 10 - 40 (m) above the water, after which the bird hovers momentarily and then plunges feet first into the water. They catch fish by diving into a body of water, oftentimes completely submerging their entire bodies. As an osprey.

Ospreys will typically eat on a nearby perch but have also been known to carry fish for longer distances.Occasionally, the osprey may prey on rodents, rabbits, hares, other mammals, snakes, frogs, birds, salamanders, conchs and crustaceans. Reports of ospreys feeding on carrion are rare. They have been observed eating dead white-tailed deer and Virginia opossum.## Adaptations.The osprey has several adaptations that suit its piscivorous lifestyle: reversible outer toes sharp spicules on the underside of the toes closable nostrils to keep.

The breeding season varies according to latitude; spring (September–October) in southern Australia, April to July in northern Australia and winter (June–August) in southern Queensland. In spring the pair begins a five-month period of partnership to raise their young. The female lays two to four eggs within a month, and relies on the size of the nest to conserve heat. The eggs are whitish with bold splotches of reddish-brown and are about 6.2 x 4.5 (cm) and weigh about 65 (g). The eggs are incubated for about.

Calocedrus decurrens. Calocedrus decurrens, with the common names incense cedar and California incense-cedar (syn. "Libocedrus decurrens" Torr.), is a species of coniferous tree native to western North America. It is the most widely known species in the genus, and is often simply called 'incense cedar' without the regional qualifier.## Description."Calocedrus decurrens" is a large tree, typically reaching heights of 30-40 (m) and a trunk diameter of up to 1.2 (m). The largest known tree, located in Klamath National Forest, Siskiyou County, California, is 47.98 (m) tall with a 12 (m) circumference trunk and a 17.5 (m) spread. Specimens form a broad conic.

Specimens can live to over 500 years old.The foliage is produced in flattened sprays with scale-like leaves 2–15 (mm) long; they are arranged in opposite decussate pairs, with the successive pairs closely then distantly spaced, so forming apparent whorls of four; the facial pairs are flat, with the lateral pairs folded over their bases. The leaves are bright green on both sides of the shoots, with only inconspicuous stomata. The foliage, when crushed,.

The cones turn orange to yellow-brown when mature about 8 months after pollination. The pollen cones are 6–8 (mm) long.## Distribution.The bulk of the tree's range is in the United States, from central-southwestern Oregon through most of California and the extreme west of Nevada, as well as a short.

Giant sequoia bears similarities to the species, but has sharp leaves. In the south–southwest U.S. some have confused bushy junipers for incense cedar.With its thick basal bark, the incense cedar is one of the most fire- and drought-tolerant plants in California. Although the tree is killed by hot, stand-replacing crown fire, it spreads rapidly after lower-intensity burns. This has given the incense cedar a competitive advantage over other species such as the bigcone Douglas-fir in recent.

It grows slowly when needed to outlast competition.This tree is the preferred host of a wood wasp, "Syntexis libocedrii" a species which lays its eggs in the smoldering wood immediately after a forest fire. The tree is also host to incense-cedar mistletoe ("Phoradendron libocedri"), a parasitic plant which can often be found hanging from its branches. Fire scars provide an entry point for "Tyromyces amarus" (pocket dry rot). "Gymnosporangium" rust disease afflicts the trees, but is rarely fatal.For numerous birds during.

Calocedrus decurrens. the wintertime, "Calocedrus decurrens" has been seen to be used for foraging. According to the United States Department of Agriculture, in areas of the Western Sierra Nevada in California, numerous species of birds are thought to use the incense cedar as a "foraging substrate" so that they can attain as much food as needed. Human impacts on these trees due to forest management practices have caused issues for many of these birds, threatening the use of the incense cedar as a forage substrate.## Uses.The wood is soft and light, and has a pleasant odor and is generally resistant to rot.

Calocedrus decurrens. It has been used for external house siding, interior paneling, and to make moth-resistant hope chests. It was once the primary material for wooden pencils, because it is soft and tends to sharpen easily without forming splinters.## Native Americans.Indigenous peoples of California use the plant in traditional medicine, basket making, hunting bows, building materials, and to produce fire by friction. A Northern California tribe used branchlets to filter out sand from water when leaching toxins from acorn meal; foliage also served as a flavoring.The Maidu Concow tribe name for the plant is hö'-tä (Konkow language).## Cultivation."Calocedrus decurrens" is cultivated as.

Sea lamprey. The sea lamprey ("Petromyzon marinus") is a parasitic lamprey native to the Northern Hemisphere. It is sometimes referred to as the "vampire fish".## Description.The sea lamprey has an eel-like body without paired fins. Its mouth is jawless, round and sucker-like, and as wide or wider than the head; sharp teeth are arranged in many concentric circular rows. There are seven branchial or gill-like openings behind the eye.

Pomegranate. The pomegranate ("Punica granatum") is a fruit-bearing deciduous shrub in the family Lythraceae, subfamily Punicoideae, that grows between 5 and 10 (m) tall.The pomegranate was originally described throughout the Mediterranean region. It was introduced into Spanish America in the late 16th century and into California by Spanish settlers in 1769.The fruit is typically in season in the Northern Hemisphere from October to February, and in the Southern Hemisphere from March to May. As intact sarcotestas or juice, pomegranates are used in baking, cooking, juice blends, meal garnishes, smoothies, and alcoholic beverages, such as cocktails and wine.Pomegranates are widely cultivated throughout.

Pomegranate. ripe fruit. Pomegranate grows easily from seed, but is commonly propagated from 25 to 50 (cm) hardwood cuttings to avoid the genetic variation of seedlings. Air layering is also an option for propagation, but grafting fails.## Varieties."P. granatum" var. "nana" is a dwarf variety of "P. granatum" popularly planted as an ornamental plant in gardens and larger containers, and used as a bonsai specimen tree. It could well be a wild form with a distinct origin. It has gained the Royal Horticultural Society's Award of Garden Merit.The only other species in the genus "Punica" is the Socotran pomegranate ("P. protopunica"),.

Anisota virginiensis, the pink-striped oakworm moth, is a species of silk moth of the family Saturniidae. == Description == The female's wings are purplish red with ochre-yellow. They have thin scales and are almost transparent. The male's wings are purplish brown with a large transparent space in the middle. The female is larger than the male. The wing span is 4.2 to 6.6 centimeters. == Habitat == The moth can be found across Canada from Nova Scotia to southeastern Manitoba, and in the United States. It lives in deciduous woodlands and suburbs. == Biology == Females release a pheromone which.

Anisota virginiensis. attracts males that swarm around her like bees. Mating occurs during the morning. It is a rapid process. The male and female stay together for the rest of the day and then the female finds a place to lay eggs, usually under oak leaves. Such mating swarms have been observed at carrion, where host plants may be higher quality due to the influx of nutrients associated with decomposition.The caterpillars are gray or greenish with dull brownish yellow or rosy stripes. There are scales on each segment and two long spines on the mesothorax. The caterpillars pupate for a short time.

Anisota virginiensis. They feed on the foliage of oak trees, maples, birches, and hazels. The caterpillar overwinters in the soil as a pupa. Caterpillars that are newly hatched or are in the middle of growing feed in groups while those that are mature or nearly so feed separately. The caterpillar is about an eighth of an inch long. The head is large in proportion to the body. The inside of the mouth is yellow. The legs are semi-translucent. == Ecology == Conservation regimes are not required for this species.

Turquoise-browed motmot. The turquoise-browed motmot ("Eumomota superciliosa") also known as Torogoz, is a colourful, medium-sized bird of the motmot family, Momotidae. It inhabits Central America from south-east Mexico (mostly the Yucatán Peninsula), to Costa Rica, where it is common and not considered threatened. It lives in fairly open habitats such as forest edge, gallery forest and scrubland. It is more conspicuous than other motmots, often perching in the open on wires and fences. From these perches it scans for prey, such as insects and small reptiles. White eggs (3–6) are laid in a long tunnel nest in an earth bank or sometimes.

Arch of Hadrian (Jerash). The Arch of Hadrian is an ancient Roman structure in Jerash, Jordan. It is an 11-metre high triple-arched gateway erected to honor the visit of Roman Emperor Hadrian to the city (then called Gerasa) in the winter of 129–130. The arch originally stood to almost 22 m and probably had wooden doors. It features some unconventional, possibly Nabataean, architectural features, such as acanthus bases. The columns are decorated with capitals at the bottom rather than the top. The monument served both as a commemorative arch and as an approach to Gerasa. The Arch's relative remoteness from the city walls points.

Shaft sinking. Shaft mining or shaft sinking is the action of excavating a mine shaft from the top down, where there is initially no access to the bottom. Shallow shafts, typically sunk for civil engineering projects, differ greatly in execution method from deep shafts, typically sunk for mining projects.Shaft sinking is one of the most difficult of all mine development methods: restricted space, gravity, groundwater and specialized procedures make the task quite formidable. Shafts may be sunk by conventional drill and blast or mechanised means.Historically, mine shaft sinking has been among the most dangerous of all the mining occupations and the preserve.

Shaft sinking. of mining contractors called sinkers. Today shaft sinking contractors are concentrated in Canada, Germany, China and South Africa.The modern shaft sinking industry is gradually shifting further towards greater mechanisation, recent innovations in the form of full-face shaft boring (akin to a vertical tunnel boring machine) have shown promise but the use of this method is, as of 2019, not widespread.## Mine shafts.Mine shafts are vertical or near-vertical tunnels, which are "sunk" as a means of accessing an underground ore body, during of the development of an underground mine.The shape (in plan view), dimensions and depth of mine shafts vary greatly.

Shaft sinking. in response to the specific needs of the mine they are part of and the geology they are sunk through. For example, in North and South America, smaller shafts are designed to be rectangular in plan view with timber supports. Larger shafts are round in plan and are concrete lined.Mine shafts may be used for a variety of purposes, including as a means of escape in the event of an emergency underground and allowing for the movement of: People Materials Mine services (such as compressed air, water, backfill, power, communications and fuel) Ventilation air Broken rock (in the form of.

Shaft sinking. payable ore, or non payable waste) Or any combination of the aboveWhen the top of the excavation is the ground surface, it is referred to as a "shaft"; when the top of the excavation is underground, it is called a "winze" or a "sub-shaft". Small shafts may be excavated upwards from within an existing mine as long as there is access at the bottom, in which case they are called "raises".A shaft may be either vertical or inclined (between 80 and 90 degrees to the horizontal), although most modern mine shafts are vertical. If access exists at the bottom of.

Shaft sinking. the proposed shaft, and ground conditions allow, then raise boring may be used to excavate the shaft from the bottom up; such shafts are called "borehole shafts".Following the Hartley Colliery disaster where the single shaft at the mine became blocked, the United Kingdom made single shaft mines illegal in 1862, establishing the practice that all underground mines must have a "a second means of egress". Many other global mining jurisdictions have adopted this rule and shafts are therefore often found in pairs (although there are multiple alternative methods of providing a second means of egress).The current the deepest single lift.

Shaft sinking. (i.e. continuous) mine shaft in the world is the 2991m deep, main shaft at South Deep Mine in South Africa, owned by Gold Fields Limited, which, along with its twin ventilation shafts, took ten years to sink and equip.## Parts of a mine shaft.The most visible feature of a traditionally-built mine shaft is the headframe (or winding tower, poppet head or pit head) which stands above the shaft. Depending on the type of hoist (or winder) used, the top of the headframe will either house a hoist motor or a sheave wheel (with the hoist motor mounted on the ground).

Shaft sinking. The headframe will also typically contain bins for storing ore being transferred to the processing facility.At ground level beneath and around the headframe is the Shaft Collar (also called the Bank or Deck), which provides the foundation necessary to support the weight of the headframe and provides a means for workers, materials and services to enter and exit the shaft. Collars are usually massive reinforced concrete structures with more than one level. If the shaft is used for mine ventilation, a plenum space or casing is incorporated into the collar to ensure the proper flow of air into and out.

Shaft sinking. of the mine.Beneath the collar the part of the shaft which continues into the ground is called the "shaft barrel".At locations where the shaft barrel meets horizontal workings there is a "shaft station" (or inset) which allows men, materials and services to enter and exit the shaft. From the station tunnels (drifts, galleries or levels) extend towards the ore body, sometimes for many kilometers. The lowest shaft station is most often the point where rock leaves the mine levels and is transferred to the shaft, if so a "loading pocket" is excavated on one side of the shaft at this.

Shaft sinking. location to allow transfer facilities to be built.Beneath the lowest shaft station the shaft continues on for some distance, this area is referred to as the "shaft bottom". A tunnel called a "ramp" typically connects the bottom of the shaft with the rest of the mine, this ramp often contains the mine's water handling facility, called the "sump", as water will naturally flow to the lowest point in the mine.## Shaft lining.Many (although not all) shafts are lined following excavation and the installation of temporary ground support.The shaft lining performs several functions; it is first and foremost a safety feature.

Shaft sinking. preventing loose or unstable rock from falling into the shaft, then a place for shaft sets to bolt into, and lastly a smooth surface to minimise resistance to airflow for ventilation.Final choice of shaft lining is dependent on the geology of the rock which the shaft passes through, some shafts have several liners sections as required Where shafts are sunk in very competent rock there may be no requirement for lining at all, or just the installation of welded mesh and rock bolts. The material of choice for shaft lining is mass concrete which is poured behind "shaft forms" in.

Shaft sinking. lifts of 6 m as the shaft advances (gets deeper).Shotcrete, fibrecrete, brick, cast iron tubing, and precast concrete segments have all been used at one time or another. Additionally, the use of materials like bitumen and even squash balls have been required by specific circumstances. In extreme cases, particularly when sinking through halite, composite liners consisting of two or more materials may be required.The shaft liner does not reach right to the bottom of the shaft during sinking, but lags behind by a fixed distance. This distance is determined by the methodology of excavation and the design thickness of the.

Shaft sinking. permanent liner. To ensure the safety of persons working on the shaft bottom temporary ground support is installed, usually consisting of welded mesh and rock bolts. The installation of the temporary ground support (called "bolting") is among the most physically challenging parts of the shaft sinking cycle as bolts must be installed using pneumatic powered rock drills.For this reason, and to minimise the number of persons on the shaft bottom a number of projects have successfully switched to shotcrete for this temporary lining. Research and development in this area is focusing on the robotic application of shotcrete and the commercialisation.

Shaft sinking. of thin sprayed polymer liners.## Shaft compartments.Where the shaft is to be used for hoisting it is frequently split into multiple compartments by "shaft sets", these may be made of either timber or steel. Vertical members in a shaft set are called "guides", horizontal members are called "buntons". For steel shaft guides, the main two options are hollow structural sections and top hat sections. Top hat sections offer a number of advantages over hollow structural sections including simpler installation, improved corrosion resistance and increased stiffness. Mine conveyances run on the guides in a similar way to how a steel roller.

Shaft sinking. coaster runs on its rails, both having wheels which keep them securely in place.Some shafts do not use guide beams but instead utilize steel wire rope (called "guide rope") kept in tension by massive weights at shaft bottom called "cheese weights" (because of their resemblance to a truckle or wheel of cheese) as these are easier to maintain and replace.The largest compartment is typically used for the "mine cage", a conveyance used for moving workers and supplies below the surface, which is suspended from the hoist on steel wire rope. It functions in a similar manner to an elevator. Cages.

Shaft sinking. may be single-, double-, or rarely triple-deck, always having multiple redundant safety systems in case of unexpected failure.The second compartment is used for one or more skips, used to hoist ore to the surface. Smaller mining operations use a skip mounted underneath the cage, rather than a separate device, while some large mines have separate shafts for the cage and skips. The third compartment is used for an emergency exit; it may house an auxiliary cage or a system of ladders. An additional compartment houses mine services such as high voltage cables and pipes for transfer of water, compressed air.

Shaft sinking. or diesel fuel.A second reason to divide the shaft is for ventilation. One or more of the compartments discussed above may be used for air intake, while others may be used for exhaust. Where this is the case a steel or concrete wall called a "brattice" is installed between the two compartments to separate the air flow. At many mines there are one or more complete additional separate "auxiliary shafts" with separate head gear and cages.## Shaft construction.The lowest point in a sinking shaft is known as "shaft bottom", shaft projects differ from some other forms of mine development in.

Shaft sinking. that all activities that take place on shaft bottom become part of the critical path for the project schedule. The infrastructure required to sink a shaft is referred to a "the sinking set-up".It is typical for progress (the "sinking rate") in the sinking phase (that is excavation, ground support and lining) of a shaft project to follow a learning curve as the project team repeat the same series of activities over and over in what is called "the sinking cycle", eventually approaching the theoretical maximum rate for that sinking set up over time. The use of experienced shaft sinkers is.

Shaft sinking. necessary to reduce the length of this learning curve and thus the duration of the project as much as possible.Key to a successful shaft sinking project are: Getting the various components of the sinking set-up correct and installed at the right time. Having experienced people involved from as early in the project as possible Using the available time on shaft bottom as efficiently as possible.Although significant emphasis is placed on the rate of progress of a project sinking cycle by shaft sinkers, sinking is only one of a number of phases in the conventional construction of a new shaft, as.

Shaft sinking. follows; "Box Cut Excavation". A box cut is a large square or rectangular excavation typically completed using earthmoving equipment down to bedrock, inside which the shaft collar will be constructed. Having the loads imposed by the collar, headframe and hoisting plant transferred into solid rock is necessary to prevent unplanned subsidence. Where the depth of bedrock is to great to for a box cut to economically viable, or the bedrock is not strong enough, civil engineering techniques such as diaphragm walls or concrete piles may be used to create a deep foundation instead. "Pre-Sink". The pre-sink is the excavation and.

Shaft sinking. support of the first 60 – 100 meters of the shaft barrel, often completed smaller equipment such as handheld, pneumatic drilling equipment to drill holes for basting and ground support and mini-excavators for mucking. During the pre-sink hoisting of muck and equipment is usually performed by a mobile crane on surface. It is necessary to sink this part of the shaft first so that the Galloway, a multi-level working platform may be installed with enough vertical distance to shaft bottom that it will not be damaged by fly rock during blasting. "Collar Construction". From the bottom of the box-cut, the.

Shaft sinking. shaft collar is constructed bottom up in a planned series of concrete pours. "Galloway (Sinking Stage) Construction & Installation." The Galloway (also known as a Sinking Stage or Scaffold) is a multi-level working platform, suspended in the shaft from winches located on surface. The Galloway allows sinkers to efficiently work on differing levels as required by the various tasks of the sinking cycle. It is typical for the Galloway to be constructed off to one side of the shaft and lowered into the pre-sink with a crane in as complete a state as possible. Once in place the Galloway is.

Shaft sinking. "chaired" (suspended from the shaft collar) while the headframe is built above, often protected by a bulkhead. "Headframe & Hoist House Construction." With the collar constructed and the Galloway installed the headframe and hoist (or winder) houses may be constructed and the hoist and winch ropes installed. Headframes may be either steel or concrete and their design will determine how they are constructed. The Galloway is moved in the shaft by means of winches, which move slowly and are rated for significant loads, while the sinking buckets (or kibbles) are moved in the shaft by the sinking hoist, which moves.

Shaft sinking. quickly and is rates for less load that the winches. To protect the hoist(s) and winches and the sensitive electronics which are used to control their operation they are normally installed inside of a build called a hoist (or winder) house. "Commissioning Sinking Set Up." The Sinking set-up must then be commissioned to ensure that all parts are operating as planned. "Full Sink". The activities of the sinking cycle (excavation, installation of temporary ground support, placement of the shaft lining and extending shaft services) all take place in this phase of construction. In a shaft where there are to be.

Shaft sinking. multiple working levels, shaft stations and station stubs (short lengths of horizontal tunnel leading away from the station) will be developed by the sinkers on the way down. As the equipment to excavate these stations must be small enough to fit through the openings in the Galloway, the rate of advance in developing the station stubs is typically low, compared to what can be achieved with full size mining equipment so station stubs are typically kept as short as possible. "Shaft Equipping & Headframe Changeover." Once the shaft reaches the final design depth, the shaft is stripped of any temporary.

Shaft sinking. services, the Galloway cut up or modified to suit the installation of the permanent shaft set-up, the shaft sets (if required) installed and the headframe / winders modified to allow for permanent hoisting. Any permanent conveyances will be installed at this stage. "Commissioning Permanent Set Up." The Permanent set-up must then be commissioned to ensure that all parts are operating as planned before being handed over to the new owner.As with the depth and design of shafts significant variations do exist in this sequence depending on local conditions, for example in that hard Canadian Shield rocks which dominate shaft sinking.

Shaft sinking. in Canada a deep and complex shaft collar is unnecessary as the bedrock is both strong and close to surface. This reduces the amount of time typically required to establish the shaft collar.Traditionally sinking contractors would build a temporary headframe for the sinking set up, which would then be dismantled to make way for a permanent headframe. With the growth in complexity and duration of shaft sinking projects over time it has become more common to incorporate more of the permanent shaft set-up into the sinking phase. This results in a reduced overall project duration, as for example, if the.

Shaft sinking. service piping used to sink the shaft does not need to be stripped out to make way for permanent piping.With the advancements made in raise boring technology, raise borers have been used to create a pilot hole for shaft sinking, where access exists at the bottom of the new shaft, in this case the sinking phase is dedicated to enlarging this pilot hole to full diameter (a process usually called "slashing"). This methodology can be considerably faster than full face sinking as muck (waste rock) from sinking falls down the pilot hole and is handled using existing mine infrastructure off.
