Mining

Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposit.These deposits form amodity that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.

Modern Strategic Mine Planning   Today at Mines

In mine planning, decisions as to how and when to act include the extraction and routing of blocks of ore, the timing of lumpy decisions such as pushbacks or transitions from open pit to underground mining, and the placement of shafts. As with financial options, the goal is to take actions that optimize the present value of the payoffs from acting.

Mining   Horizontal openings: drifts  Britannica

Mining Mining Horizontal openings: drifts: All horizontal or subhorizontal development openings made in a mine have the generic name of drift. These are simply tunnels made in the rock, with a size and shape depending on their usefor example, haulage, ventilation, or exploration. A drift running parallel to the ore body and lying in the footwall is called a footwall drift, and drifts
