A long passage for the admission or outlet of air; an air shaft.
In a column or colonette, the shaft is the vertical pole that exists between the base and the capital. Shafts can be plain, fluted or ornate. See also Ionic, Doric, Composite, Corinthian.
A vertical or semi vertical excavation into the earth. Underlay shaft is on an angle.
A vertically developed opening in a cave, wider than a chimney.
a vertical passage in a cave formed by water dripping or flowing through vertical cracks in the bedrock.
Vertical entry to a mine latterly using powered winding gear and cages to supply, ride men and materials and take out coal. Formerly using a windlass or other manual means of winding. Usually sited in pairs. (Upcast and Downcast). Since Hartley Colliery Disaster 1862.
A long, narrow passage in underground mines created for the extraction of valuable material.
a shaft provides principal access to the underground workings for transporting personnel, equipment, supplies, ore and waste.A shaft is also used for ventilation and as an auxiliary exit. It is equipped with a surface hoist system that lowers and raises conveyances for men, materials and ore in the shaft. A shaft generally has more than one conveyancing compartment.
A vertical hole like a well dug into the ground to access a vein of paydirt. Can range from a few feet deep to well over a hundred.
A vertical accessway to a mine. Shafts are used in the movement of personnel and materials, including ore and non-mineralized rock.
A vertical access that begins at ground level and ends within the earth. Shafts often have multiple compartments that are used for various purposes including personnel hoisting, rock or hoisting and piping and other utility access. Shafts are used for mining in regions where ground elevations are relatively uniform.
something long and thin such as a long board or a hole in a building or a narrow tunnel into the ground The boat's drive shaft appeared to be made of inferior metal. The mine was illegal and there was no effective equipment to monitor the build-up of gas in the shaft.
A vertical entrance to an underground mine.
a vertical passageway through a building (as for an elevator)
(architecture) upright consisting of the vertical part of a column
a vertical passage into a mine
a pit or well sunk from the ground surface into a tunnel for the purpose of furnishing ventilation or access to the tunnel
A vertical or inclined excavation used for the purpose of opening or servicing a mine.
vertical adit that provides access to mineralization below the surface exposures.
A mine-working (usually vertical) used to transport miners, supplies or equipment.
a vertical passageway to an underground mine used to raise to surface or lower to underground personnel, equipment, supplies and material and to raise ore and waste rock to surface.
An excavation of limited area compared with its depth, made for finding or mining ore or coal, raising water, ore, rock, or coal, hoisting and lowering men and material, or ventilating underground workings. The term is often specifically applied to approximately vertical shafts, as distinguished from an incline or inclined shaft. A shaft is provided with a hoisting engine at the top for handling men, rock, and supplies, or it may be used only in connection with pumping or ventilating operations.
A vertical or inclined tunnel used for access, transportation, ventilation or water removal.
Vertical underground drop. The most feared obstacle underground.
a vertical tunnel giving access to a coal seam; used mainly when access is not practical by slope, or when the coal lies at great depth
A usually small, vertical (or near vertical) excavation made for finding coal, ventilation, and hoisting equipment and personnel from underground workings.
A vertical passageway to an underground mine for moving personnel, equipment, supplies and material including ore and waste rock.
vertical or decline - means of transporting men and materials
A vertical or steeply inclined excavation or opening from the surface (usually) down through the strata to the coal or mineral to be developed.
Vertical or slightly inclined entrance for access, haulage or pumping.
A vertical or subvertical excavation used for accessing an underground mine; for transporting personnel, equipment and supplies; for hoisting ore and waste; for ventilation and utilities; and/or as an auxiliary exit.
a vertical passage in an underground mine used for transporting personnel, equipment, supplies and mined material
(1) a vertical or inclined excavation in a mine extending downward from the surface or from some interior point as a principal opening through which the mine is exploited. A shaft is provided with a hoisting engine at the top for handling men, rock, or supplies, or it may be used only in connection with pumping or ventilating operations. Often, the interior is timbered in such a way that each entity has its own passageway or compartment (cage, ski, manway or pipe); (2) an excavation of limited area compared with its depth, made for access to underground mine workings; (4) vertical or inclined underground working excavated downwards. Commonly used for hoist-based transportation of workers and/or ore and waste rock.
A vertical or nearly vertical opening into the earth for mining.
a vertical entrance to a mine cut downward from the surface.
A nuclear device exploded at the bottom of a drilled or mined vertical hole. Some safety tests were set off at the bottom of unstemmed drilled holes, producing a "Roman candle" effect.
A vertical or nearly vertical opening into the Earth's surface.
a vertical or inclined conduit providing access from the surface to underground orebodies.
A vertical or inclined excavation for the purpose of opening and operating a mine. It is usually equipped with a hoist at the top which raises and lowers the cage and skip. A shaft may also be used for ventilating underground workings.
A vertical, underground passage.
The vertical segment of a column or pilaster between the base and the capital.
A vertical hole down to a mine.
A vertical or steeply inclined excavation for the purpose of opening and servicing a mine. It is usually equipped with a hoist at the top which lowers and raises a conveyance for handling personnel and materials.
A primary vertical or non-vertical opening through mine strata used for ventilation or drainage and/or for hoisting of personnel or materials; connects the surface with underground workings.
A vertical or inclined tunnel from surface for the conveyance of men, materials, hoisting ore, pumping water and providing ventilation.
Vertical entrances into mines.
A vertical or inclined opening sunk from the surface of the ground into or body. It is often used in finding ore, draining water, ventilation, lowering and hoisting men, and lowering materials.
1. The main, cylindrical part between the ends of a column or pillar. 2. A vertical opening passing through the floors of a building. 3. The long stem or body of a tool or weapon. 4. A bar that supports or transmits motion to a mechanical part of an engine.
A mine working, extending from the surface down; can be vertical or inclined. Used to move men and equipment in and out of the mine and to move ore out of the mine.
the main vertical section of a column
An enclosed space extending through one or more stories of a building, connecting vertical openings in successive floors, or floors and the roof.
Large vertical duct used for housing services or lifts.
A vertical or inclined excavation in rock for the purpose of providing access to an orebody. Usually equipped with a hoist at the top, which lowers and raises a conveyance for handling workers and materials.
