App. II-13-2 <br /> Since 1961 the coal has been "washed" in the preparation plant, which is situated at <br /> the central complex yard. Rock and other impurities, separated from the salable <br /> coal, have been deposited in refuse piles. <br /> There are two refuse piles. The "Old Pile" is situated on the east side of the central <br /> complex yard, adjacent to the parking lot. Refuse from the washing process was <br /> deposited on the old pile until 1985. <br /> The "Sutey Pile" has received preparation plant refuse since 1985, and will be the <br /> site for disposal of refuse until the completion of mining. <br /> 6. Adit/Rock Tunnel. <br /> Face-up work for the Adit/Rock Tunnel portal began in 1979. It was a cut and fill <br /> program, with the fill used for a yard area outside the portal. <br /> As materials were excavated from the tunnel, a permanent fill area was constructed <br /> south of the portal. In addition, the portal yard was extended, using materials from <br /> the tunnel excavation, in 1987. <br /> Surface facilities have been constructed on the fill. <br /> Extension of the Adit/Rock Tunnel to the B-bed and the M-bed, in the areas of No. 1 <br /> and No. 2 Mines, have allowed use of the twin bores of the Adit/Rock Tunnel as the <br /> major transportation artery in the mine operation since the fall of 1987. <br /> In addition, conveyor belts have replaced truck haulage as the chief means of <br /> surface coal transport, and of refuse disposal. <br /> As mentioned previously, however, the Adit/Rock Tunnel must be completed, <br /> including lateral extensions to the workings of Nos. 3, 4 and 5, in order to entirely <br /> replace the use of the mountain trucks, haul roads and portals for coal haulage. <br /> 7. Anticipated Development. <br /> The modernization program will be continued. Major facets include: <br /> Raw coal storage will be in underground bunkers. Face-up work has been done for <br /> these bunkers. Presently, storage is in open piles. <br /> The Adit/Rock Tunnel will be continued through to the west side of Huntsman Ridge, <br /> allowing an additional escapeway and ventilation intake. <br /> Lateral extensions to the workings of Nos. 3, 4 and 5 will allow transportation to and <br /> from these areas by the Adit/Rock Tunnel, thus replacing the haul roads and portals <br /> as the major transportation arteries for haulage of coal, machinery and materials. <br /> 4 <br />
