Abstract

Compilation and analysis of publicly available data on Federal coal are resulting in voluminous map sets showing coal isopachs, structure contours, and overburden isopachs on each known minable coal bed. As of spring 1981, there are available from the US Geological Survey Open-File Services Section in Denver map sets at 1:24 000 scale or microfiche sets covering approximately 470 of the ultimately 1400 quadrangles in the program. A typical map set has a short text and about 20 plates, including a data sheet; a Federal mineral ownership map; and correlation charts. For each coal bed, there are isopachs, structure contours, stripping limits, and mining ratios extending as far as the data will permit, regardless of coal ownership. Reserve base tonnages and relative development potentials are calculated, but only for unleased Federal coal areas. -from Author
