Strip mining is any form of mining involving the extraction of mineral deposits that lie in large horizontal beds close to the earth's surface. In area strip mining, used where the terrain is fairly flat, a gigantic earthmover strips away the overburden, and a power shovel-which can be as tall as a 20-story building-removes the mineral deposit ...
