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.

Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine a pit, and the
The Coal Resource: A Comprehensive Overview of Coal 7 The choice of mining method is largely determined by the geology of the coal deposit. Underground mining currently accounts for about 60% of world coal production, although in several important coal producing countries surface mining is more common. Surface mining accounts for around 80% of
field investigations he began in 1873. Commercial coal mining began in the district in 1892. Then, Marius R. Campbell, U.S. Geological Survey, mapped the geology and discussed the coal resources in two classic reports, the Pocahontas Folio (1896) and the Tazewell Folio (1897), which include the map area.
