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.

Environmental Code of Practice for Metal Mines Canada.ca

Surface mines, also known as open pit mines, are preferred for the extraction of ore close to the surface. Deeper or more irregularly shaped ore bodies are generally mined by underground methods. The mine workings are excavated by drilling and blasting. Drills are used to drill patterns in the rock that, upon blasting, will fragment the rock.
