Coal analysis as well as analysis of the immediate floor and roof for the upper <br />seam is included in Appendix 4(1). <br />Coal analysis as well as analysis of the immediate floor and roof for Drill Hole <br />N-16 (Federal lease modification area PR-05) is included in Appendix 4(2). <br />Coal analysis and analysis of the immediate floor and roof for Federal Lease <br />COC-60941 will be completed and reported upon entry of the property. <br />Coal analysis and analysis of the immediate floor and roof for the Tipotsch <br />Lease will be completed and reported upon entry of the property. <br />GEOLOGIC HAZARDS <br />Geologist, David L. Gaskill, of the Conservation Division of the U.S.G.S. <br />reported no unusual geologic hazards are known that might adversely affect mining <br />in the upper or lower Menefee coal seams. He noted that ground water tables were <br />below the seams (See Appendix 4(3)). Mr. Gaskill's report was prepared in February, <br />1980, for the survey's consideration of National King Coal's application for a new <br />Federal Lease adjacent to the current lease holdings. <br />• <br />STRATIGRAPHIC CROSS-SECTION <br />A cross-section of the King I Mine shows several coal seams or rider seams at <br />various depths from the surface (See Appendix 4). The overburden above the King I <br />Mine (upper Menefee) seam consists exclusively of sandstone and shale. The cross- <br />section was obtained from an exploratory core drill hole on the mine plan area <br />(Federal Lease). The information was obtained in 1977. The drill hole is located in <br />the SE/4 NW/4 of Section 32, and is shown on King I-005. Additional drilling log <br />data and Colorado Geological Survey data are included in Appendix 4, and locations <br />of referenced samples are shown on Regional Geology Map King 1-004. <br />The second cross-section shows the basic geology of La Plata County of which <br />the Hay Gulch area is a part. The section is helpful in visualizing the geology <br />mentioned above (See Appendix 4). <br />Data obtained from an exploratory core drill hole within the federal lease <br />modification area added by Permit Revision PR-05 is included as Appendix 4(2). <br />0 <br /> <br />National King Coal, LLC King I Mine <br />Section 2.04.6 <br />PaoP 4 FFhrnian7 9007
