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 a mineralized package 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.
Underground Mining Methods and Applications - UFRGS Room-and-pillar mining is designed for fiat-bedded deposits of limited thickness, such as copper shale, coal, salt and potash, limestone.
Underground mining is used in areas where the environmental impact of a surface operation is too great or the limestone deposit is located too deep. Most underground mining uses the room-and-pillar method, in which the limestone is removed by blasting, and columns of .
