Surface mine is a coal-producing mine that is usually within a few hundred feet of the surface. [[Earth]] above or around the coal (overburden) is removed to expose the coalbed, which is then mined with surface excavation equipment, such as draglines, power shovels, bulldozers, loaders, and augers. It may also be known as an area, contour, open-pit, strip, or auger mine.
