Open Pit Mining Flashcards

-refers to a surface mining method where an ore body is extracted in increments to its economic depth-generally massive ore bodies with large vertical extent near the surface-waste usually removed from the pit and transported to an area outside pit limits-rock material must be strong enough to permit having benches-Top OB may be removed by scrapers
