Mining Flashcards | Quizlet

A form of surface mining in which bulldozers, power shovels, or stripping wheels remove the overburden in strips. It is used in areas with fairly flat terrain. An earthmover strips the overburden and then a power shovel digs a cut to remove the mineral deposit. It is typically used for coal and some phosphate rock.
