Sep 26, 2013· The deepest open pit mines are scattered geographically across the world unlike the deepest underground mines, which are mostly concentrated in South Africa. The majority of the deepest open pit operations in the world are copper producing mines. Miningtechnology profiles the world''s top ten deepest open pit mines currently active.
Sep 19, 2019· These are all very essential parts of shaft mining, as water, fuel and air play an extremely important role in keeping the mine—and its workers—fully operational. On the surface, a head frame is used to winch lifts up and down the shaft. This is done through a hoist motor, which is usually connected to a sheave wheel.
