−	A '''surface mine''' is a [[mine]] that is usually within a few hundred [[feet]] of the surface. [[Earth]] above or around the coal (overburden) is removed to expose the coal bed, which is then mined with surface excavation equipment, such as drag lines, [[power shovel]]s, [[bulldozers]], loaders, and [[auger]]s. It may also be known as an area, contour, open-pit, strip, or auger mine.	+	'''surface mine'''
