• Openpit Mining

    Openpit mining occurs on surface and is generally the cheapest way to extract ore. This is because rock doesn't have to be moved far up hill against gravity, equipment used can be larger than underground, and it doesn't require more expensive features like ventilation, communiions, etc. that underground does.

  • 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.
