Abstract
This survey was conducted to determine the magnitude of the methane emission and control problem in U.S. bituminous coal mines. The resultant data indicate that the emission rate for any given coalbed depends primarily on the coal production rate and on mine depth, as well as on the nature of the coalbed and the surrounding strata. An excellent correlation was found between (1) the methane emission rate and (2) the product of coal production rate and mine depth for the mines in the Pittsburgh, Pocahontas Nos. 3 and 4, and the Illinois Nos. 5 and 6 coalbeds. The highest total emission rates found in U.S. bituminous coal mines were as follows, in million cubic feet per day: Monongalia County, West Virginia, 39; Marion County, West Virginia, 30.4; McDowell County, West Virginia, 13.1; Washington County, Pennsylvania, 11.9; Greene County, Pennsylvania, 11.4; Buchanan County, Virginia, 21.6; Jefferson County, Alabama, 10.3; and Franklin County, Illinois, 6.6.
