Surface mining Simple English Wikipedia, the free

Surface mining is a method which operates on the surface of the land. Machines remove the overburden to get at material, such as coal, below it. Surface mining includes strip mining, open-pit mining (UK open cast mining) and mountaintop removal mining. It is mining in which soil and rock overlying the mineral deposit are removed.
