Wes! E!k A4ine <br />• The minable areas of the E and B-Seams can be seen by comparing Map 13 (B-Seam thickness) <br />with Map 18 (E-Seam thickness). E and B-Seam mine plans, maximizing the recovery of the <br />E and B-Seam reserves, are shown in Map 51 and Map 52, respectively. <br />Mountain Coal Company plans to mine coal from the E and B-Seams in a descending <br />sequence. A descending sequence was chosen to maximize reserve recovery and improve <br />overall ground conditions during second seam mining. <br />Mountain Coal Company has assessed the recoverable coal reserves of the Federal coal leases <br />contained in the E and B-Seams. Mountain Coal Company's best estimate is that there are <br />164.6 million tons of recoverable reserves in the E and B-Seams (Table 28). <br />Table 28 Estimate of Recoverable Coal Reserves at the West Elk Mine <br />Recoverable Reserves (millions of tons) <br /> <br />Seam Lease <br />COC-56447 Lease <br />COC-54558 Lease <br />D-044569 Lease <br />C-0117192 Lease <br />C-1362 MCC Fee & <br />Fee Lease <br />Total <br />E 0.3 0.0 0.5 0.0 53.3 9.0 63.1 <br />B 33.6 9.0 5.3 5.9 42.7 5.0 101.5 <br />Total 33.9 9.0 5.8 5.9 96.0 14.0 164.6 <br />• Note: Recoverable reserves are based upon Curren[ mine plans. <br />The mine plan was laid out to recover as much coal as possible with consideration for <br />personnel and equipment safety and surface protection. The percent of recovery in the <br />development (room and pillar) sections is approximately 40 percent, more or less, depending <br />upon pillar design. Longwall panel extraction is 100 percent of the mining height, which is <br />planned at approximately 12.0 feet for the B-Seam and 11.0 feet for the E-Seam. The overall <br />recovery of the mine layout has not been calculated, because it varies with changes in mine <br />plans. <br />Coal recovery depends on the method of coal extraction. Using room and pillar methods, <br />Mountain Coa] Company recovered about 50 percent of coal reserves in the F-Seam. With the <br />longwall mining method, Mountain Coal Company recovers (and plans to recover) about 70 <br />percent of in-place coal reserves of the B and E-Seams (Table 29), based upon current mine <br />plans. <br /> <br />2.05 8/93Stip.48; Revised Jan. 1994 PROS; 8.~94TR71; Revised Jun. 1995PR06 <br />
