From Shovels to Machines

Beginning in the late 1940s, coal companies rapidly introduced longwall and continuous mining machines. Longwall machines sheer coal from the face in a circular motion. The broken coal falls into a pan line, which leads to a conveyor belt and then to the processing plant. Longwall machines now extract more than 55 percent of all West Virginia coal mined underground. Continuous miners are used ...
