  • What is Longwall Mining (with pictures)

    Nov 12 2020 · Longwall mining was first introduced in the 1950s and 1960s. Today it accounts for more than half of all coal production in the United States. On any given day a typical longwall mining system is capable of extracting between 10 000 and 30 000 tons (9 to 27 million kilograms) of coal from a panel.

  • Basic Information about Surface Coal Mining in Appalachia

    Layers of rock and dirt above and between the coal seams are removed. Coal seams are removed with excess soil and rock placed in an adjacent valley. Large scale earth moving equipment is used to excavate and remove coal from lower layers. The equipment used depends on the method and scale of the surface mining method being employed.
