In 1972, the Bureau of Mines developed a direct-method test for measuring the gas content of virgin coal core samples for coal mine health and safety considerations. Since that time, approximately 1,500 coal samples from more than 250 coalbeds in 17 states have been collected for gas content determination. The gas content data, when combined with geologic and engineering studies, can be used as a basis for a preliminary estimate of mine ventilation requirements, and to determne whether methane drainage in advance of mining should be considered. The data are also critical in delineating coalbed resources and in utilization feasibility studies. This report makes the Bureau's extensive data base of gas content data more readily available to the coal and gas industries. The data are presented in tabular form, alphabetically by coalbed name and by state. The components of the total gas content (lost, desorbed, and residual gas) are given. Location (state and county), sample depth, coalbed or formation name, and coal rank are included for geographic and geology identification.
