Machines Used in Coal Mining Career Trend

Twenty percent to 30 percent of mined coal underground is from longwall mining. This is performed by a mechanical cutter that shears coal off from a panel on the seam. The panel being worked on may be up to 800 feet in width and 7000 feet in length. Mined coal is deposited onto a conveyor that moves the coal to a collection area.
