Mining Wikipedia
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.

Surface Mining, Industry of Metals, Minerals, Precious
Surface mining is a form of mining in which the soil and the rock covering the mineral deposits are removed. It is the other way of underground mining, in which the overlying rock is left behind, and the required mineral deposits are removed through shafts or tunnels.. Surface mining is basically employed when deposits of commercially viable minerals or rock are found closer to the surface

Ecological Effects of Subsurface Mining dummies
Surface mining techniques don’t work for extracting all valuable geologic resources. Diamonds and most metal ores, including gold, require extensive subsurface mines to access the rocks with these resources in them. Subsurface mines are probably what you envision when you think of mining: systems of tunnels and vertical shafts with elevators to take miners underground []
