Abstract

The USGS Coal Quality database is an interactive, computerized component of the NCRDS. It contains comprehensive analyses of more than 13,000 samples of coal and associated rocks from every major coal-bearing basin and coal bed in the U.S. The data in the coal quality database represent analyses of the coal as it exists in the ground. The data commonly are presented on an as-received whole-coal basis.
