Section - 2.053 <br />Elk Creek Coal Handling, Support, and Ancillary Facilities -The following descriptions reflect <br />the current configuration of the Elk Creek facilities and include facilities modifications and <br />relocations completed in conjunction with the 1997-1998 facilities expansion activities. See the <br />General Facilities Maps, (Map 2.05-M1), and the Facilities Detail Maps, (Map series 2.05-M3x). <br />A. Coa] Storage Areas -Coal is stockpiled in the Elk Creek coal stockpile area. The Elk Cxeek <br />coal stockpile receives coal from the Elk Creek Mine overland conveyors, which discharge <br />to the headhouse of Stacking Tube No. 1. Coal can be routed from this discharge point to <br />either of the two main stacking tubes. The Elk Creek coal stockpile has a live storage <br />capacity of approximately 100,000 tons, with additional dead storage capacity of at least <br />200,000 tons. The Elk Creek stockp$e includes asub-grade reclaim system capable of <br />handling up to 3,500 tons per hour. Additional details on coal handling facilities are <br />provided in the subsequent coal handling section. (Formerly, during the operation of the <br />Sanborn Cxeek mine, the East Yaxd coal stockpile area could hold 30,000 yards of coal from <br />either truck haulage or via a short transfer conveyor) <br />B Coal Screening Facilities -The coal stockpile reclaim conveyor will discharge to a coal <br />screening installation constructed adjacent to the existing dump station. The screening <br />installation's main function is to segregate product-sized (-2-inch) material that can then <br />bypass the crusher in order to maximize overall system capacities. The coal screening <br />installation is fully enclosed within apre-fabricated steel building for dust control. A <br />portable coal pre-screen is also used to screen stockpiled coal prior to truck loading and <br />offsite haulage Additional details on coal handling facilities are provided in the subsequent <br />coal handling section. <br />C Crusher Bypass Conveyor -The screen undersize from the coal screening facility will meet <br />product specifications without further crushing ox sizing. In order to minimize required <br />crusher throughput, a crasher bypass conveyor was installed to route the screen undersize <br />around the crasher. The bypass conveyor runs from the screening facility to the point at <br />which the crusher discharges to the silo transfer conveyor. Additional details on coal <br />handling systems axe provided in the subsequent coal handling section. <br />D Dump Station, Scales, and Storage Bins -The dump station, located in the Elk Creek <br />Facilities area, receives coal from either the coal screening facility via the main coal stockplle <br />tedaim system or Fmes from the pre-screen. Additional details on coal handling facilities are <br />provided in the subsequent coal handling section. <br />E. Tipple, Crusher, and Transfer Conveyors -The tipple was previously used as a loadout <br />point fox the Somerset Mine when the mine was a rail haul operation. The tipple is now an <br />intermediate transfer point where coal from the dump station is crushed and where coal <br />from both the crusher and the crusher bypass conveyor discharge to the silo transfer <br />conveyor. Additional details on coal handling facilities are provided in the subsequent coal <br />handling section. <br />F. Coal Storage Silo and Transfer Conveyor -The coal storage silo was previously used as the <br />primary storage and loading point Eor unit train loading but has been replaced by the batch <br />weigh loadout. The silo is now used as an intermediate storage point, receiving coal from <br />the tipple via the silo transfer conveyor and discharging to the loadout transfer conveyor. <br />The sIlo provides approximately 8,000 tons of live storage capacity. Additional detaIls on <br />coal handling facilities are provided in the subsequent coal handling section. <br />G. Coal Sampling System - A coal sampling system on the batch-weight transfer conveyor <br />periodically collects a coal sample from the transfer conveyor fox quality control purposes. <br />The sampling system and associated ancillary equipment axe contained in a small metal <br />MR78 2.05-13 Rev.
