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 .

If the depth to the mine was less than 50 feet below road grade, a deep-mine undercut was performed, similar to that for structures. This involved the excavation of overburden materials and inspection of the exposed mine. The removal of the coal mine was not required if all voids were removed or fully collapsed during excavation.
