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 is a 39pit39, and

Surface mining can be used when the coal is buried less than 200 feet underground. In surface mining, giant machines remove the topsoil and layers of rock to expose large beds of coal. Once the mining is finished, the dirt and rock are returned to the pit, the topsoil is replaced, and the area is replanted.
Other underground coal mines are laid out in a checkerboard of rooms and pillars Fig. 2, and the mining operation involves cyclical, step bystep mining sequences. The rooms are the empty areas from which coal has been mined, and the pillars are blocks of coal generally 40 to 80 feet on a side left to support the mine roof.

In surface mining, the ground covering the coal seam the overburden is first removed to expose the coal seam for extraction. The elements of a surface mining operation are 1 topsoil removal and storage for later use, 2 drilling and blasting the strata overlying the coal seam, 3 loading and transporting this fragmented overburden material called spoil, 4 drilling and blasting the
Coal mining is only a temporary use of land, so it is vital that rehabilitation of land takes place once mining operations have stopped. In best practice a detailed rehabilitation or reclamation plan is designed and approved for each coal mine, covering the period from the start of operations until well after mining has finished.
