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.

Surface coal mine area monitoring using multi-temporal

Apr 01, 2011 In surface coal mining large volumes of waste material are excavated and removed from one place to another causing continuous change in topography with time. Large amounts of rock and are stripped and stored which consequently creates huge holes and huge piles in the landscape and leaves “scars” on the Earth surface.

Surface mining Wikipedia

Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.. Surface mining began in the mid-16th century [dubious
