The Four Main Methods of Mining

 · Strip mining is done only when the ore body is in close proximity to the surface. Open-pit mining – Open-pit mining is the method in which minerals or rocks are extracted from the Earth via an open pit or borrow. Mountaintop removal mining – Mountaintop removal mining (MTR) is done by mining coal seams underneath mountaintops.

Open Pit Surface 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.
