Open cast mining is a type of surface mining in which mineral resources are removed from the earth through large holes or pits dug into the surface. The term "open cast mining" is used most commonly in Great Britain. In the United States, open cast mining is usually called open-pit or open-cut mining.
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.
