West Elk Mine <br />Conveyors <br />Run-of-mine coal is transported from the longwall production and continuous miner <br />development sections to the various surface facilities by a system of belt conveyors. A 60-inch <br />mine conveyor carries coal from the mine portal to the stacking tubes. At a speed of 900 feet <br />per minute, the capacity of this conveyor is approximately 3,500 tons per hour. The conveyor <br />belting is covered by a semi-circular corrugated galvanized metal cover. Primary and <br />secondary walkways were constructed along the conveyor. The conveyor structure is steel. A <br />reclaim feeder was installed on the run of mine belt near the portals in 1987. <br />From the stacking tubes, the 54-inch underground conveyor reclaim system transports the coal <br />to a double-roller crusher. This conveyor has a capacity of 1,500 tons per hour and will travel <br />at 550 feet per minute. The crushed coal is transported to the screening plant on a 60-inch <br />high-angle conveyor belt with a capacity of 1,500 tons per hour. Product-sized coal that passes <br />through the screens is transported to the silo conveyor belt (S-1) on a 48-inch, 1,500 tons per <br />hour conveyor belt. Over-sized material is transported to the rotary breaker on a 48-inch high- <br />angle conveyor with a capacity of 300 tons per hour. Product-sized material that passes <br />through the rotary breaker is transported to the silos on conveyor S-1, and oversized material <br />is dropped into the reject bin. <br />Conveyor TC-1 is a 350-foot long, 36-inch wide conveyor belt designed to convey ROM coal <br />material from a loader-fed hopper near the ROM coal stack tube ST-1 stockpile to the TC- <br />1/PR-2 Transfer Tower. The ROM coal material is transferred from the TC-1 conveyor to the <br />PR-2 conveyor within an enclosed portion of this tower. The tower is designed large enough <br />for oversized-material scalping equipment to be added at a future time. Conveyor PR-2 is a <br />2,000-foot long, 48-inch wide conveyor designed to convey ROM coal material from conveyor <br />TC-1 via the TC-1/PR-2 Transfer Tower to the Preparation Plant located on the LRP mine <br />facilities bench (LRP). This conveyor follows the ground for approximately half its length and <br />is elevated using bent (open structural-steel support) structures of varying length for the other <br />half of its length. <br />The S-1 conveyor belt to storage Silo No. 1 and Silo No. 2 has been upgraded from a 42-inch <br />to 48-inch width belt. The conveyor belting is covered by a semi-circular corrugated <br />galvanized metal cover. Primary and secondary walkways were constructed along the <br />conveyor. The conveyor structures are steel. <br />A crushed (product-sized) coal stack-tube and storage area will be fed by 48-inch conveyor from <br />the top of Silo No. 2 to the top of the ST-3 stack-tube. The conveyor belt has a capacity of 1,500 <br />tons per hour. A dozer trap and 48-inch reclaim conveyor located west of the silos, has the <br />capacity to reclaim coal from the silo pad of 1,500 tons per hour. <br />A 72-inch belt conveyor carries coal from the storage silos to the over-the-track train loadout. <br />This conveyor has a capacity of 6,000 tons per hour and runs at a speed of 850 feet per <br />minute. Total length is approximately 600 feet. The conveyor is covered by a semi-circular <br />corrugated galvanized metal cover.
