What is Strip Mining?

Strip mining is a form of surface mining that is employed to strip away a layer or seam of soil, natural vegetation, and rocks (known as overburden) to extract the mineral deposits underneath. Unlike underground mining, it is predominately used to access relatively flat sedimentary mineral reserves that are near the earth's surface, usually coal and lignite.
