An adit (from Latin aditus, entrance) [1] or stulm [2] is a horizontal or nearly horizontal passage to an underground mine. [3] Miners can use adits for access, drainage, [ 4 ] ventilation, and extracting minerals at the lowest convenient level. [ 1 ]

adit, a horizontal or near-horizontal passage driven from the Earth’s surface into the side of a ridge or mountain for the purpose of working, ventilating, or removing water from a mine.

Mar 25, 2024 · An adit is a horizontal passage leading into a mine for access or drainage, whereas a tunnel is a passageway dug through the earth or rock to allow passage from one side to another, often used for transportation.

Dec 11, 2024 · Adits have been instrumental in mining and construction, serving as horizontal or gently sloping passageways into hillsides or mountains. They facilitate ventilation, drainage, and material transport while minimizing excavation compared to vertical shafts.

Mar 26, 2017 · Equipment for driving is of four general types—drilling, blasting, loading and transportation, and ventilating. Modern drilling equipment comprises rock drills; rock-drill accessories, including drill mountings, hose, and fittings; drill-steel and drill-sharpening equipment; air-compressor and motive power; and pipe lines for air and water.

Dec 17, 2022 · Drift mining can refer to one of two things: mining an ore deposit by underground mining or working coal seams through adits. A mining drift is an underground mine where the entry is above water level and typically on the slope of a hill.

Adit - A nearly horizontal passage from the surface by which a mine is entered and dewatered. A blind horizontal opening into a mountain, with only one entrance. Angle of dip - The angle at which strata or mineral deposits are inclined to the horizontal plane.

Mine shafts and adits can be closed by filling, plugging, or capping, or by installing barriers, gating, or fencing. An underground mine can have a shaft, which is a vertical opening; or an adit, which is a horizontal tunnel; or both. Purposes of a mine shaft or adit closure are to: reduce or prevent contamination of surface and groundwater.

Dec 31, 2017 · An adit is a horizontal or near-horizontal passageway to a larger underground excavation for the purposes of ventilation, water removal, or auxiliary entrance. The short tunnels are used in both mining and tunneling to access the main shaft at strategic points.

When mining almost horizontally into a hillside, a mine might employ the use of an adit, which is a largely horizontal opening with only one point of contact with the surface. In this type of mine...
