Study Notes
Mining Terminology
-
Shaft: Vertical passage for ventilation, drainage, and personnel/materials hoisting; connects surface and underground.
-
Drift: Horizontal passage close to an ore body, running parallel to the ore vein.
-
Stope: Excavated area from which ore has been extracted.
-
Raise: Vertical/inclined passage connecting levels above or used for exploration above a level.
-
Winze: Vertical/inclined passage sunk to connect with a lower level or explore ground below a level.
-
Level: Horizontal passages or drifts worked from shafts to access different mining areas.
-
Sump: Lowest point in the mine for collecting drainage water.
-
Crosscut: Horizontal opening linking a shaft to a vein, driven across the vein’s direction.
-
Headframe: Structure at the top of the shaft supporting the hoist rope pulley and often the hoist.
-
Backfill: Material like sand or dirt used to fill spaces in shafts or tunnels for stability.
-
Ore Pass: Shaft designed for transporting ore and mining waste within a mine, reducing hauling distances.
-
Mucking: Loading broken rock using machines or by hand, with mucking machines often replacing manual labor.
-
Face: Exposed area of a coal bed being actively mined.
-
Timbering: Method of supporting walls of trenches or tunnels with wooden structures for safety during excavation.
-
Ventilation: Process of supplying fresh air and removing contaminated air underground; crucial for miner safety, controlling gas and dust.
-
Shotcrete: Concrete or mortar applied using a hose for ground support and rock stabilization in underground mining.
-
Collar: Entrance of the shaft, built with sturdy materials for stability; includes ventilation and power supply elements.
-
Cut and Fill: Controlled ore extraction method; involves excavating a slice of ore, backfilling with waste, then repeating the process.
-
Decline: Inclined passageway for accessing underground areas, allowing vehicle travel without vertical shafts.
-
Development: Construction of necessary infrastructure (tunnels, shafts) to access and prepare ore bodies for extraction.
-
Gouge: Clay-like material from fault zones, impacting stability and posing risks such as collapses.
-
Hanging Wall: Rock above an inclined vein, also known as the roof in bedded deposits.
