• 2.05.3 <br />Coal Storage Piles <br />Coal is stored in one of two open stockpiles at the D-Seam portal level. The <br />coal storage piles are; 1) run-of-mine and 2) stoker coal. Up to 100,000 tons <br />will be stored in the piles at any one time. A stacking tube is used to transfer <br />the coal into the run-of-mine coal stockpile in order to minimize segregation <br />and air particulate emissions. A radial stacker is utilized to stockpile the <br />stoker coal. The downhill conveyor transports crushed coal to the coal <br />storage pile located along old State Highway 133. Up to 350,000 tons of <br />coal will be stored in the highway stockpile. <br />Downhill Convevor Transfer Building <br />The downhill conveyor transfer building is a structural steel building where <br />the transfer belt from the crushing and screening building terminates. The <br />coal transfers to the downhill conveyor. The dimensions of the building are <br />approximately 16 feet by 16 feet by 25 feet high. <br />Stacking Tubes <br />The 2"XO" coal is stacked at the highway stockpile by three concrete tubes to <br />minimize coal segregation and air particulate emissions. One tube is <br />approximately 100 feet high, one is 120 feet high and the third is 130 feet <br />high. They are 12 feet in diameter and are equipped with 4 foot square <br />openings to allow coal to flow from the tube to the stockpile area. One of the <br />stacking tubes is located directly on the reclaim tunnel. <br />Reclaim Tunnels <br />Two 13 foot diameter, 350-foot long and 200 feet long, multi-plate tunnels <br />are located at the highway stockpile. One feeds the unit train loadout and <br />the other feeds the wash plant. Two 42-inch diameter, 160 foot and 150 foot <br />long escape tubes provide ventilation and emergency exit from the west <br />(closed) end of the reclaim tunnels. Both escape tubes terminate at a <br />concrete fan housing that is approximately 6-feet by 6-feet by 8-feet high. <br />I <br />Coal Preparation Plant <br />The preparation plant is a structural steel building where coal and rock are <br />separated with heavy media circuits. The wash plant is a closed system, no <br />water is discharged. The structure is approximately 55 feet by 70 feet by 80 <br />feet high. An adjacent motor control center room is approximately 10 feet by <br />12 feet by 12 feet high. An adjacent synfuel plant is approximately 35 feet by <br />10 feet bv, 25 feet hia~ and will be housed in a metal buildina,, <br />MR-60 2.05 - 14 - 07/05 <br />A~PRav~ <br />8~19~05 <br />
