Degasification of United States Coalbeds.
The New Sketch Dhanbad India 1978 Jan; :182-185
U.S. coalbeds contain significant resources of high-quality gas. This gas can be drained from the coalbeds before or during mining. No technological breakthrough is necessary to make drainage and utilization of gas from coalbeds economically and technically feasible in the immediate future. This paper describes several methods for degasifying coalbeds that have been developed by the Bureau of Mines.
