Coal mining Wikipedia

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

Coal Mining Methods emfi.mines.edu

In “conventional” room-and-pillar mining, production occurs in five steps: mechanically undercutting the coalbed, drilling holes into the bed for explosives, blasting the coal, loading the broken coal into shuttle cars for delivery to a conveyor, and then bolting the mine roof in the excavated area. To provide a steady flow of coal in a room-and-pillar mine, several stages of mining occur
