The Mining Process Of Coal

  • What is the process of mining coal? AskingLot

    Coal Mining and Processing. Coal miners use giant machines to remove coal from the ground. They use two methods: surface or underground mining. Once the mining is finished, the dirt and rock are returned to the pit, the topsoil is replaced, and the area is replanted.

  • Coal Mining and Production MIGA

    2018-8-5 · The depth, thickness, and configuration of the coal seams determine the mode of extraction. Shallow, flat coal deposits are mined by surface processes, which are generally less costly (per ton of coal) than underground mines of similar capacity. Strip mining is one of the most economical surface processes. Here removal of overburden and coal extraction proceed in parallel strips along the face of the coal deposit, with the spoil being deposited behind the operation in the previously mined areas. In open pit mining, thick seams (tens of meters) are mined by traditional quarrying techniques. Underground mining is used for deep seams. Underground mining Coal mining Coal preparation Britannica,Coal preparation. As explained above, during the formation of coal and subsequent geologic activities, a coal seam may acquire mineral matter, veins of clay, bands of rock, and igneous intrusions.In addition, during the process of mining, a portion of the roof and floor material may be taken along with the coal
