Surface mining and deep underground mining are the two basic methods of mining. Seams relatively close to the surface, at depths less than approximately 180ft (50m), are usually surface mined. Coal that occurs at depths of 180 to 300ft (50 to 100 m) are usually deep mined, but in some cases surface mining techniques can be used.
