Coal Mining And Processing. Coal is mined by two methods: surface or 'opencast' mining or underground or 'deep' mining. Surface mining is used to produce most of the coal in the U.S. because it is less expensive than underground mining. Surface mining can be used when the coal is buried less than 200 feet underground.
