    The longwall method involves using a machine called a shearer Mechanical cutting machine used to extract coal in underground mines. that looks like a huge plow. The shearer slowly pushes and cuts through the coalface. It recovers the loosened ore as it advances and lets the roof collapse behind it.

  • Coal preparation plant Wikipedia

    ROM coal is delivered with large variations in production rate of tonnes per hour (tph). A ROM stockpile is used to allow the washplant to be fed coal at lower, constant rate. A simple stockpile is formed by machinery dumping coal into a pile, either from dump trucks, pushed into heaps with bulldozers or from conveyor booms.

    The land can then be used for croplands, wildlife habitats, recreation, or offices or stores. Underground mining, sometimes called deep mining, is used when the coal is buried several hundred feet below the surface. Some underground mines are 1,000 feet deep. To remove coal in these underground mines, miners ride elevators down deep mine shafts
