  • 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.Everything You Need To Know About Open Pit Mining,2018-11-1 · Open pit mining (also known as strip mining) is the process of extracting ore, minerals and/or fossil fuels that occurs on the surface of a particular mining site.

    2016-4-18 · Open-pit surface mining involves the removal of rock from the surface to form large, open pits (Banglam, Ataei, & Sayadi, 2012). Rock that is removed from the open pits, referred to as waste rock, overburden, or spoil, is moved to nearby piles or adjacent valleys where they are stored until reclamation of the open pit is commenced (Banglam, Ataei, & Sayadi, 2012). The past 30 years of open-pit mining Coal Mining and Production MIGA,2018-8-5 · coal deposit, with the spoil being deposited behind the operation in the previously mined areas.
