Coal is classified according to its energy and sulfur content as anthracite, bituminous, subbituminous, or lignite. Energy content is greatest in anthracite and lowest in lignite coal. The sulfur content of coal is important because low-sulfur coal emits less sulfur dioxide and as a result, is more desirable as a fuel for power plant Strip mining is a surface mining process in which the overlaying layer of soil and rock is stripped off to reach the coal. The environmental effects of this vary based on topography, climate, and reclamation processes but one serious problem is acid mine drainage (the drainage of acidic water from mine sites).
