surface coal mining and processing equipment

Jul 01, 2016 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. Regrading begins as coal excavation continues. Once coal removal is complete, final regrading takes place and the area is revegetated.
