No. 2 to the top of the stacktube. The conveyor belt has a capacity of 1,500 tons per hour. A 72- <br />inch underground reclaim conveyor will have the capacity to carry coal from the storage azea to the <br />train loadout belt at a rate of 6,000 tons per hour. A dozer trap and 48-inch reclaim conveyor to be <br />located west of the silos, will have the capacity to reclaim coal from the silo pad of 1,500 tons per <br />hour. <br />A 72-inch Loadout conveyor carries coal from the storage silos to the over-the-track loadout. This <br />conveyor has a capacity of 6000 tons per hour and runs at a speed of 850 feet per minute. Total <br />length is approximately 600 feet. The conveyor is covered by a semi-circulaz corrugated galvanized <br />metal cover. The portion of the conveyor that crosses the North Fork of the Gunnison River is <br />completely enclosed. Primary and secondary walkways were constructed along the conveyor. The <br />conveyor structure is steel. <br />Construction of three stacking tubes and an underground conveyor reclaim system was begun <br />during 1991 and became operational in July of 1992. The approximately 100,000 to 120,000 tons of <br />run-of--mine coal storage provided by these tubes is needed to handle the higher longwall <br />production volumes. The storage azea will be expanded by moving a portion of the main topsoil <br />stockpile to the south, creating an additional 60,000 to 88,000 tons of coal storage area. Run-of- <br />mine coal is fed directly to these tubes. Bulldozers push the coal into the hoppers feeding the <br />underground reclaim system and into the crusher. The stacking tube facility consists of three <br />stacking tubes ranging in height from 91 to 94 feet and are constructed of reinforced concrete. On <br />top of each stack tube is a transfer structure. The transfer structures aze approximately 38 feet tall, <br />open steel structures. The facility also includes a 60 foot tall feed conveyor drive tower and a 42 <br />foot high crusher building. Both of these aze open steel structures. An as-built construction <br />description is provided in Exhibit 68. <br />Construcfion of a screening facility was begun in 1992 and became operafional in February of 1993. <br />The facility is used to sepazate over-sized material (typically consisting of rock) from the product- <br />sized coal. The screening facility consists of an open steel structure with a maximum height of 84 <br />feet and three associated conveyors. A 1,500 tons per hour high-angle conveyor transfers material <br />to the screening plant from the crusher, product-sized coal is transported to the silo conveyor belt <br />on a 1,500 tons per hour conveyor and a 300 tons per hour high-angle conveyor transports over- <br />sizedmaterial to the rotary breaker. An as-built construction description is provided in Exhibit 68. <br />Two silos provide temporary storage for product coal. These silos provide the storage capacity <br />needed to accommodate Mountain Coal Company's production schedules and use of unit trains for <br />shipping product coal from the West Elk Mine. The reinforced concrete silos provide about 24,000 <br />tons of product coal storage capacity. The silos were designed to reduce the hazard of spontaneous <br />combustion by minimizing dead storage azeas within the silo compartments. <br />2.05-41 Revised Jan. 1997 TR79 <br />
