Open Pit Mining an overview ScienceDirect Topics

open-pit mining Mining. a method of mining in which the surface excavation is open for the duration of mining activity, employed to remove ores and minerals near the surface by first removing the waste or overburden and then breaking and loading the ore. Used to mine thick, steeply inclined coalbeds and also used extensively in hard-rock mining for metal ores, copper, gold, iron, aluminum, and other minerals.
