R. Saunders - Underground and Radioactive

Drift—A horizontal underground opening that follows along the length of a vein or rock formation, as opposed to a crosscut, which crosses the rock formation.

Dry—A building where an underground worker changes into working clothes.

Face—The end of a drift, crosscut, or stope in which work is taking place.

Grizzly (or mantle)—A grating, usually constructed of steel rails, placed over the top of a chute or ore pass for the purpose of stopping large pieces of rock or ore that might hang up in the pass.

Hoist—The machine used for raising and lowering the cage or other conveyance in a shaft.

Jackleg—A percussion drill used for drifting or stoping that is mounted on a telescopic leg, which has an extension of about 2.5 meters. The leg and machine are hinged so that the drill need not be in the same direction as the leg.

Lagging—Planks of unfinished lumber that have many uses in a mine.

Manway—An entry used exclusively for personnel to travel from the shaft bottom or drift mouth to the working section; it is always on the intake air side in gassy mines. Also, a small passage at one side or both sides of a breast. It is used as a traveling way for the miner and sometimes as an airway, or chute, or both.

Misfire—The complete or partial failure of a blasting charge to explode as planned.

Raise—Similar to a manway but used mostly for lifting material into a stope.

Rock bolting—The act of supporting openings in rock with steel bolts anchored in holes drilled especially for this purpose.

Skip—A self-dumping bucket used in a shaft for hoisting ore or rock.

Slag—The vitreous mass separated from the fused metals in the smelting process.

Slash—The process of blasting rock from the side of an underground opening to widen the opening.

Station—An enlargement of a shaft made for storing and handling equipment and for driving drifts at that elevation.

Stope—An excavation from which ore has been removed in a series of steps. Usually applied to highly inclined or vertical veins but frequently used as a synonym for room and pillar mining.

Tailings—Material rejected from a mill after most of the recoverable valuable minerals have been extracted.

Tailings pond—A low-lying depression used to confine tailings, the prime function of which is to allow enough time for heavy metals to settle out or for cyanide to be destroyed before water is discharged into the local watershed.
