Method(s) of Mining and Coal Production Both underground and surface mining methods are used in the Midwest. Shaft and slope mines extract coals to depths of 800 feet in the deeper parts of the Basin. Three methods of surface extraction include area mining (commonly referred to as "strip mining") contour mining and auger mining.
