General description
Overburden, the material between the surface of the land and the coal seam, is removed using draglines, dozers and/or trucks and shovels, including electric rope shovels. Coal is then extracted and loaded onto haul trucks using surface miners, excavators, dozers, scrapers, backhoes and other machinery and equipment. Coal is taken to a stockpile or delivered directly to customers via conveyor or short haul rail. After mining, draglines and/or trucks and shovels are used to backfill the overburden that was removed at the beginning of the process to allow for site reclamation.
