This report discusses and analyzes total U.S. coal resources in the broad sense, including both identified and undiscovered resources. The coal resources of the U.S. remaining in the ground on January 1, 1974, are estimated to total 3,968 billion tons. The new U.S. estimate is a 23-percent increase over previous estimates, made possible by an increased program of geologic mapping, exploration, and study during the past few years by Federal and State agencies and by private industry. The identified tonnage has been classified in all States according to rank. It has also been classified by thickness of overburden, degree of reliability of estimates, and thickness of beds in 21 States. Coal thus classified is well distributed in all coal provinces and presents about 60 percent of the total identified tonnage. This large classified tonnage is, therefore, resonably representative of the total identified resources.
