2.05.3 <br />Gunnison River. The D -Seam mine portals are located about 800 feet <br />above old State Highway 133 at an elevation of approximately 6880 feet <br />where the D-2 Seam outcrops. The B -Seam mine portals will be located <br />about 550 feet above old State Highway 133 at an elevation of approximately <br />6630 feet. The loadout is located along the mainline of the Union Pacific <br />Railroad at an elevation of approximately 5880 feet. The surface facilities <br />consist of sediment control structures, coal handling facilities, unit train <br />loadout, support facilities for mine operations and other related facilities. <br />(3)(a) Following is a discussion of the proposed mine facilities: <br />Portal Conveyor Transfer Buildings <br />The D -Seam portal conveyor transfer building is a structural steel building <br />where the main belt from the mine terminates. The coal from the mine will <br />transfer to the stockpile conveyor. Gob conveyed from the mine will be <br />transferred to the gob belt. The dimensions of the building are approximately <br />20 feet by 24 feet by 45 feet high. The B -Seam will have a similar transfer <br />building. Gob conveyed from the B -Seam will be transferred via a steel <br />chute to a concrete gob bin. Coal conveyed from the B -Seam is transferred <br />to the uphill conveyor. <br />Stacking Tube <br />The raw coal is stacked by this concrete tube to minimize coal segregation <br />and air particulate emissions. The tube is approximately 85 -feet high and <br />12 -feet in diameter. It has 4 foot openings to allow coal to flow from the tube <br />to the stockpile area. The stacking tube is located directly on the reclaim <br />tunnel. <br />Reclaim Tunnel <br />The reclaim tunnel is located under the stacking tube and a 70,000 ton <br />stockpile. It is of reinforced concrete construction. The typical inside <br />dimensions of the tunnel are 13 feet high by 12 feet wide. The tunnel is <br />approximately 245 feet long. A 36 -inch diameter escape tube is located on <br />the east end of the tunnel. The 120 foot long escape tube terminates at a <br />concrete fan housing that is approximately 6 feet by 6 feet by 8 feet high. <br />Screen and Crusher Building <br />The screen and crusher building is a structural steel building that is <br />approximately 52 feet high. The building houses a double deck screen and <br />crusher. It has the capability of producing 2"x0" crushed coal and stoker <br />sized coal. The dimensions of the building are approximately 40 feet by 21 <br />feet by 52 feet high. <br />TR -76 2.05-13- 12/26/12 <br />
