0 2.05.3 <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 />M 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 />MCC Building <br />There are two motor control center buildings. One located on the D -Seam <br />portal bench northeast of the screen and crusher building is a cinder block <br />building. It is approximately 18 feet by 42 feet with an 11 foot eave height. It <br />has a concrete roof. One is located on the Hubbard Creek shaft pad. It is <br />approximately 15 feet by 25 feet with a 12 foot eave height. <br />10 PR-12 2.05-13- 02/10 <br />
