In situ determination of methane gas in Utah coal mines (a case history)

Prepr., Soc. Min. Eng. AIME; (United States) (1983)

V.J. Hucka U.W. Lisner

Coal, which was discovered in Utah in 1849, covers about 18% of the total area. Production in 1981 was more than 14 million tons. However, some Utah coal mines are quite gassy. If longwall face technology is applied, then a release of a high volume of methane may be expected during the mining process. Investigations on methane content have been made by use of an isothermic bubble desorbometer. The desorbable methane content of 5 m/sup 3/ to 16 m/sup 3/ of methane per ton of coal mined has been determined.

Methane formation and retention in coal

V.J. Hucka

The methane content of coal seams in Utah and Colorado will be measured in situ as well as in the laboratory and correlated with the geological and geochemical history of the seams and surrounding strata. Chemical and physical properties will be measured in the laboratory for coals that obtain methane and coals of similar rank which do not contain methane. Methane yields on pyrolysis will be used to measure the propensity of coals to form additional methane. Methane formation and retention will be interpreted in terms of the physical and chemical properties of the coal and the chemical and geological history of the coal seam. 2 refs., 18 figs., 1 tab.

Filtration methods of in-situ gasification of coal seams. [Czechoslovak experiments]

V.J. Hucka Barun K. Das

Two different types of filtration methods for in-situ gasification of coal are described. The different factors, i.e., geological, technological, and others, which affect in-situ gasification are given. The layout and operation of filtration methods of in-situ gasification are described in detail. The results of a case history are described.
