and Map 53B shows the location of the West Elk Mine's topsoil and subsoil stockpiles. These <br />stockpiles aze appropriately signed and will be maintained according to applicable regulations for <br />the life of the mine or until used for reclamation. Handling of topsoil is more thoroughly discussed <br />in Section 2.05(4). When a topsoil stockpile is expected to remain inactive for more than one yeaz, <br />it is seeded with the permanent or temporary seed mix (described in Section 2.05.4.). This seeding <br />will protect the stockpiles from wind and water erosion. <br />(6) Overburden <br />Because the West Elk Mine is an underground mine and not a surface mine, no overburden is <br />removed, handled, or stored. Spoil from developing underground workings is handled as coal mine <br />waste. Therefore, the discussion of refuse disposal in Section 2.05.3(8) also applies to all spoil <br />generated during these developmental activities. <br />(7) Coal Handling Structures <br />At the West Elk Mine, coal handling structures consist of belt conveyors, three run-of--mine <br />stacking tubes with an underground conveyor reclaim system, adouble-roller crusher, screening <br />plant, rotary breaker, two silos, a crushed coal stacktube with an underground conveyor reclaim <br />system, a proposed dozer trap reclaim system, and a railroad loadout facility. Map 53 shows the <br />locations of these coal handling structures. Each facility or group of facilities is described below. <br />Run-of--mine coal is transported from the production panels to the various surface facilities by a <br />system of belt conveyors. A 60-inch mine conveyor tames coal from inside the mine portal to the <br />stacking tubes. At a speed of 900 feet per minute, the capacity of this conveyor is approximately <br />3500 tons per hour. The conveyor belting is covered by a semi-circulaz corrugated galvanized metal <br />cover. Primary and secondary walkways were constructed along the conveyor. The conveyor <br />structure is steel. A reclaim feeder was installed on the run of mine belt neaz the portals in 1987. <br />From the stacking tubes, the 54-inch underground conveyor reclaim system transports the coal to a <br />double-roller crusher. This conveyor has a capacity of 1,500 tons per hour and will travel at 550 feet <br />per minute. The crushed coal is transported to the screening plant on a 60" high-angle conveyor <br />belt with a capacity of 1,500 tons per hour. Product-sized coal that passes through the screens is <br />transported to the silo conveyor belt (S-1) on a 48", 1,500 tons per hour conveyor belt. Over-sized <br />material is transported to the rotary breaker on a 48" high-angle conveyor with a capacity of 300 <br />tons per hour. Product-sized material which passes through the rotary breaker is transported to the <br />silos on conveyor S-1 and oversized material is dropped into the reject bin. <br />The S-1 conveyor belt to Storage Silo No. 1 and Silo No. 2 has been upgraded from a 42-inch to <br />48-inch width belt. The conveyor belting is covered by asemi-circular corrugated galvanized metal <br />cover. Primary and secondary walkways were constructed along the conveyor. The conveyor <br />structures are steel. <br />A new crushed coal stacktube and storage azea will be fed by 48-inch conveyor from the top of Silo <br />2.05-40 Revised Jan. 7997 TR79 <br />
