Abstract
Methane in coal constitutes a serious hazard during mining. Draining the methane from large blocks of coal in advance of mining is an effective method of improving the safety and efficiency of coal mining. Because of the similarity of the two gases, drained methane can be recovered and added to pipeline supplies of natural gas. To effectively apply advance drainage techniques and recover drained gas, a gross estimate of the methane content of coal is necessary. Using data from previous investigations, the virgin reserves of the Pittsburgh coal in the central and southwestern parts of Washington County, Pennsylvania, are estimated at over 1.5 billion tons, with a methane content of 50 to 100 ft3/ton. The Pittsburgh bed in this area of approximately 265 mi2 contains over 130 billion ft3 of methane.
