The kinds of coal, in increasing order of alteration, are lignite (brown coal--immature), sub-bituminous, bituminous, and anthracite (mature). Coal starts off as peat. After a considerable amount of time, heat, and burial pressure, it is metamorphosed from peat to lignite. Lignite is considered to be "immature" coal at this stage of development because it is still somewhat light in color and it remains soft. As time passes, lignite increases in maturity by becoming darker and harder and is then classified as sub-bituminous coal. The degree of alteration (or metamorphism) that occurs as a coal matures from peat to anthracite is referred to as the "rank" of the coal. Back to Coal Information Proceed to Methods of Mining.

Viewed from a satellite, West Virginia's mountaintop-removal mines are ash-gray scabs surrounded by the deep green of Appalachia's hardwood forests. At ground level, the vast mining sites exhale clouds of asthma-inducing coal dust and poison watersheds with selenium, arsenic, and sulfate. Cindy Rank, who chairs the mining committee for the West Virginia Highlands Conservancy, has spent decades fighting the practice.
Now, as the U.S. coal industry slouches toward extinction, she has a new concern. "If [the coal companies] leave and don't have any money to take care of the problems that they're leaving behind, then everybody's in trouble," she explains. "Those of us who are citizens of Appalachia and West Virginia will be paying one way or another—with our money or with our health.
