However,the oldest known underground mine,a hematite mine at Bomvu Ridge,Swaziland(Gregory,1980),is from the Old Stone Age and believed to 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.
