The mining of these seams is not planned. These seams are, in ascending <br />order, the A Seam, the C Seam, the D Seam, and the F Seam. The A Seam is typically less than <br />five feet in thickness and occurs too close below the B Seam to be economically recoverable. <br />Likewise, the C Seam is typically thin, split with rock partings or absent in the West Elk Mine <br />coal lease area. The C Seam also lies sufficiently close to the overlying B Seam to allow <br />recovery of both seams using longwall mining methods. Likewise, the D Seam occurs as a thin <br />coal bed in the West Elk Mine coal lease area and occurs too close below the E Seam to be <br />economically recoverable. Where the D Seam merges with the overlying E Seam, the upper <br />portion of the D Seam may be mined locally, with the E Seam. Previous mining operations in <br />the F Seam have been unsuccessful. Because of seam thinning, poor roof conditions and coal <br />quality, attempts to recover the F Seam have historically proven to be uneconomic. <br />Typical <br />Table 31 3 <br />Equipment Used in L ngwall Mining at West Elk Mine ? <br />Equipment T e Principal Use <br />Double Ended Ranging Shearer <br />Lon wall Face <br />2 Le Hydraulic Shields <br />qTransports <br />Pan Line With Chain Conveyor <br />l To Sta e Loader <br />H draulic Pum Station <br />& Pamine Advance <br />Power Distribution Center <br />Provides Electric Power To Shearer <br />Conveyor and Other Equipment <br />Lon wall Support Equipment <br />Move Equipment From Outside and <br />Between Panels <br />MCC will take all reasonable actions necessary to minimize waste and damage to the remaining <br />coal resources by appropriate mine design and extraction techniques. <br />Operation Description <br />The primary mine facilities and portals were developed in Section 16, T13S, R90W in 1981 and <br />1982 to support continuous miner room and pillar mining in the F Seam.
