Core samples of coal and rock were obtained from the HQ-1 environmental test well at the Pricetown I, Underground Coal Gasification Test Site. A comprehensive analytical program was performed to characterize the coal samples. The rocks associated with the coals are composed of clay size material containing low amounts of organic matter and hydrocarbon gas relative to the coal seams. The fine grained sediment above and below the coal seams appear to be an effective gas seal. The coals were encountered in two intervals of 1 foot and 6 feet thickness separated by 2 feet of shale. The coals are classified as high volatile A or B bituminous based on vitrinite reflectance, fixed carbon, and calorific value. Coal maceral analysis shows that the coal is heterogeneous in petrographic properties. The vitrinite group is the predominant maceral constituent. Fusinite, semi-fusinite, massive micrinite, and sporinite are present in varying amounts. The distribution of porous fusinite layers within the coal seams may be important in the reverse linkage stage of the gasification process. The coal in the bottom seam contains an average of 45.6 standard cubic feet of free methane per ton of coal. This methane may assist in initiating the gasification process. …
