Abstract:
The Grundy is thickest to the southeast and thins to the west and northwest. Six coarsening-upwards parasequences can be identified within the Grundy. These contain the Banner/Elswick coal zone, the Splashdam/Splitseam coal zone, the Hagy and Hagy Rider coals, the Millard/Glamorgan coal zone, and the Clintwood/Hance coal. Coal beds are generally thin and pinch out or are truncated to the northwest. Westward, coal-bearing parasequences are largely replaced by quartzarenites of the Corbin and Hazel Patch Sandstone Members.
As most of eastern Kentucky's coal beds occur above drainage or at relatively shallow depths, there has been little coalbed-methane exploration. However, parts of the Grundy and underlying formations are more than 1,000 ft below drainage in the southern Eastern Kentucky Syncline, and the Middlesboro syncline on the Pine Mountain overthrust sheet. Currently, there is no CBM production from these coal beds, but plans are being made to sample coals for their methane content. In addition, adsorbtion isotherms will be analyzed for selected coals in order to determine their potential for CO2 storage or enhanced methane production with CO2 storage.
