This report is part of a continuing program by the U.S. Geological Survey, State Geological Surveys, and the Coal Analysis Section of the
U.S. Department of Energy to provide chemical data on the composition of important coal beds of the United States of America. Such data are useful in determining the economic value of a coal, environmental effects of coal mining and coal use, and the adaptability of a coal to cleaning and to other technological processes of coal treatment and usage.
