Methane content and geology of the Hartshorne Coalbed in Haskell and Le Flore counties, Oklahoma.
Pittsburgh, PA: U.S. Department of the Interior, Bureau of Mines, RI 8407, 1979 Jan; :1-14
The Bureau of Mines developed data on the methane content of the Hartshorne coalbed, Haskell and Le Flore Counties, Oklahoma. The methane content is calculated to be between 1.1 and 1.5 Trillion cubic feet, based on an estimate of total coal in place of 2.4 To 3.2 billion short tons. Methane increases with depth, but the rate of increase decreases with greater depths. Degasification in advance of mining is recommended for all mines operating at depths greater than 500 feet to reduce hazards and methane explosions, decrease mine ventilation costs, and conserve the natural gas that would be otherwise wasted.
