Drill Hole Logs <br /> <br />Exhibit I, Drill Hole Logs, contains the lithologic logs which shown and <br />describe the lithologic characteristics and thickness of each strata in <br />each coal seam. The locations of the drill holes presented in Exhibit <br />7, Drill Hole Logs, are shown on the Geology/Hydrology Map (Map 7). <br />Also 5~. P' oy-l5/: <br />Overburden and Interburden Analyses <br />Three samples were taken from the floor and the roof of the "A" Coal <br />Seam in the vicinity of the portal area for the planned Coal Gulch Mine. <br />These three samples were analyzed at Bookcliffs Commercial Laboratories. <br />The bottom sample was basically classified as a shale with some small <br />amount of interbedded coal or carbonaceous shale. The two top samples <br />analyzed were taken because Sample No. 1 is classified as a shale with <br />some amount of carbonaceous shale; this sample extends only <br />approximately 12 to 18 inches above the top of the "A" Coal Seam. The <br />second top sample taken is a sandstone which on tap of the Sample No. 1 <br />• (the shale/carbonaceous shale). The results of the detailed analyses <br />performed on these samples are set forth in Table 2, Overburden and <br />Interburden Analyses. <br />Although it is anticipated that no groundwater will be discharged from <br />the mine entries, these overburden and Interburden samples were analyzed <br />in order to determine if any potential problems would result. As can be <br />seen from the results in Table 2, Overburden and Interburden Analyses, <br />no problems are anticipated with regard to the roof or floor material. <br /> <br />• <br />2.04-15 O <br />
