Recoverable coal is the coal that is, or can be, extracted from a coal bed during mining. The International coal Classification of the Economic Commission for Europe recognizes two broad categories of coal, “brown coal” and “hard coal.” In terms of U.S. coal classification, the international classification of brown coal includes lignite and lower-ranked subbituminous coal, whereas hard coal includes all higher rank coals.
