    Exposives and Coal MiningExposives and Iron MiningExposives and Copper MiningExposives and Crushed RockminingCoal is extracted principally in two ways: surface mining and underground mining. The mining method used depends primarily on the depth of the coal bed from the surface and the surrounding terrain. Coal beds deeper than 100 to 200 feet or on hilly terrain are usually mined by underground methods, while those at lesser depths are surface mined. Surface mining accounts for about 60 percent of the total U.S. coal production of 1 billion tons/year. A large surface mine can be three miles long and a mile wide. Un
