• Site-Specific Geology <br />The A Coal Seam roof consists of 10 to 12 feet of shale and sandstone. <br />In general, the roof material is reasonably competent, but is subject to <br />some deterioration when exposed to the cycles of moisture attendant with <br />mine ventilation. <br />The floor of the A Coal Seam is characterized by 5 to 12 feet of <br />interbedded sandstones and shales. The floor is sufficiently competent <br />for the operation of mining equipment. <br />The overburden above the A Coal Seam varies from a few feet near the <br />north and south edge of the mining area to over 200 feet in areas near <br />the central portion of the permit area. <br />Coal Quality <br />• The coal seam to be mined at the Peacock Coal Mine will be the A Coal <br />Seam; the quality of the A Coal Seam appears to be quite uniform <br />throughout the area. Typical analysis of the A Coal Seam on an <br />as-received basis is as follows: <br />Btu/lb 13,426 <br />Moisture (%) 4.01 <br />Ash (%) 5.37 <br />Sulfur (°,6) 0.54 <br />Location of Subsurface Water <br />No water is present in the abandoned or current workings of the Peacock <br />Coal Mine. Because the existing workings dip to the south, any water <br />encountered in the mine should drain to the old portal. However, no <br />water has been encountered draining from the old or existing workings. <br />All of the data obtained to date by Sunbelt for the Peacock Coal Mine <br /> <br />2.04-12 <br />
