National Coal Resources Data System (NCRDS)

The U.S. Geological Survey Energy Resources Program has developed coal databases to monitor the location, quantity, and physical and chemical characteristics of U.S. coal and coal-related deposits.  The National Coal Resources Data System (NCRDS) database is an integrated system utilizing commercial software to produce maps, resource calculations, and coal quality location maps.  NCRDS correlates and standardizes coal data from Federal and State agencies, universities, the private sector, and foreign countries. NCRDS is comprised of three major components, of which two are available online:

• Coal distribution data (USCOAL) containing published coal-resource estimates for coal bearing states listed by state, county, coal field, geologic age, formation, rank, coal thickness, overburden thickness, and reliability of resource estimates.

• Coal point-source and chemical data (COALQUAL) containing geodetic location, field observations, sample analyses, bed thickness; lithology; depth of burial, moisture, ash, and sulfur content, heat value, and major-, minor-trace-element contents.

• A point-source stratigraphic database (USTRAT), which is supported by a federally-funded cooperative program with geological surveys and universities in 23 States. Some stratigraphic data are publicly available. Index of public points by state and county (Updated July 2008 -- spreadsheet format). Contact the USGS for a download of publicly available data. Plans to update the online availability of USTRAT are underway.
