Conservation of methane from Colorado's mined/minable coal beds: a feasibility study
Technical Report
·
OSTI ID:6706388
Coal bed methane, a well documented hazard in coal mines, is also a potential energy source. In Colorado, an estimated resource of 38.8 TCF may exist in the Green River, Raton Mesa, San Juan River, and Uinta coal regions. Methane content for minable coalbeds ranges from 0 to near 500 cubic feet of gas per ton of coal. The presence of coal bed methane depends on geologic factors, while development of coal bed methane depends on geologic, mining, economic, and legal factors which must be considered in determining the feasibility of a coal degasification project. Vertical, horizontal, and directional hole degasification methods are summarized, and a case study of the Hawk's Nest Mine area, Somerset, Colorado, is included. 157 references, 29 figures, 15 tables.
