  • Open-pit mining Wikipedia

    Open-pit, open-cast or open cut mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow.. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining.Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface.

  • Basics of an open pit mine

    Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.
