Primarily used for extracting coal, strip mining involves the removal of rock and soil above a seam or layer. The removal of the exposed mineral is what follows next. The process is repeated until the exhaustion of the ore. Finally, quarry mining is used to extract the minerals used in granite, clay, sand, and gravel.
