    What are the advantages of open-cast mining? Quora

    When an ore body is near the suface, open cast mining is the answer. If an ore body is deep, then one has to sink a shaft, which is vastly more costly than open cast mining. Here in South Africa, our aging gold deposits are so deep, that we have some of the deepest mines on the planet.

    Basics of an open pit mine Mine Engineer.Com

    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.
