Abstract |
Data are compiled in this report on the total remaining coal resource of the United States, the production of coal in 1970 by mining method, sulfur content, ash content, and BTU value. Production of all coal has been projected to 1976. Projections have also been made in three sulfur categories: less than 1.0 percent, 1.0 to 2.0 percent, and 2.1 percent or more sulfur. The total remaining coal resource of the United States, as of December 31, 1970, is estimated at 1,576 billion tons, consisting of 693 billion tons of bituminous coal, 420 billion tons of subbituminous coal, 447 billion tons of lignite, and 16 billion tons of anthracite.
