Bureau of Mines.; Geological Survey (U.S.)] -- Definitions of coal resource classification terms used by the U.S. Bureau of Mines and U.S. Geological Survey. The National Coal Resources Data System (NCRDS) was designed by the U.S. Geological Survey (USGS) to meet the increasing demands for rapid retrieval of information on coal location, quantity, quality, and accessibility. An interactive conversational query system devised by the USGS retrieves information from the data bank through a standard computer terminal.

This U.S. Geological Survey Coal Quality (COALQUAL) Database Version s By Curtis A. Palmer1, Charles L. Oman1, Andy J. Park1, and James A. Luppens2 1U.S. Geological Survey, Reston, VA 2U.S. Geological Survey, Denver, CO Abstract Coal has often been described as one of the most difficult materials to sample because of its inherent heterogeneity. Statistics and information on the worldwide supply of, demand for, and flow of minerals and materials essential to the U.S. economy, the national security, and protection of the environment. Published annually, this Government report contains estimates covering nonfuel mineral industry structure, Government programs, tariffs, and 5-year salient. The United States Geological Survey (USGS, formerly simply Geological Survey) is a scientific agency of the United States scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization has four major science disciplines, concerning biology, geography, geology, and executive: James F. Reilly, Director.

@article{osti_, title = {A handbook on practical coal geology}, author = {Thomas, L.}, abstractNote = {As outlined in the preface, this book is intended as a basic guide for coal geologists to use in their everyday activities, but it is not intended to be a definitive work on any particular aspect of coal geology. The book discusses coal as a substance in terms of its . Economic evaluations of undiscovered mineral resources provide important context in which to consider the results of quantitative mineral resource assessments. The U.S. Geological Survey economic analysis method uses a simple engineering cost model approach developed by the U.S. Bureau of Mines that applies mine and mill engineering cost. Most of the stratigraphic data used for this assessment were provided to these U.S. Geological Survey (USGS) regional studies on a confidential basis by various coal companies. Introduction The Wilcox Group of northeast Texas contains shallow (less than ft) coal deposits that are mined for use in mine-mouth electric power generating plants. This includes participation in the National Coal Resources Data System (NCRDS) State Cooperative Program. The Division provides accurate and reliable coal point and stratigraphic information for the USGS NCRDS database by utilizing an extensive resource of gas and oil well logs, including driller logs, completion reports, and geophysical logs.
