Important Underground Mining Facts What The Future Holds

Underground Mines Are Extremely Deep. Generally, every mine is deep, but underground mines are much more profound than surface mines. Surface mines can not go lower than 200 feet into the Earth, but with subterranean mining, it goes deeper than that. Most underground mines reach depths of approximately 2,500 feet.

Mining

Heavy machinery is used in mining to explore and develop sites, to remove and stockpile overburden, to break and remove rocks of various hardness and toughness, to process the ore, and to carry out reclamation projects after the mine is closed. Bulldozers, drills, explosives and trucks are all necessary for excavating the land.
