GENERAL MINE PLAN COMPLIANCE: -The longwall was operating in longwall panel E4 at approximately cross-cut 25 (station 44+00). -Development has been completed in the longwall panel E5 headgate (in anticipation of a late 1Q14/early 2Q14 longwall move). Development work in the E6 headgate is at approximately cross-cut 9 (station 13+00). -The E-Seam South Mains have been developed to approximately cross-cut 79. -All of the mining at the West Elk is progressing as permitted and shown on approved Map 51 -E-Seam Projected Operations. PROCESSING WASTE/COAL MINE WASTE PILES—Rule 4.10 and 4.11 Drainage Control; Surface Stabilization;Placement: -The operator was hauling refuse material to the RPEE at the time of the inspection. All of the refuse that has been hauled to the RPEE was spread and compacted at the time of the inspection. The pile was well graded and appeared to have positive drainage. There was no water pooling on the pile. The operator was in the process of removing topsoil from the next lift of the RPEE. There was a large pile of topsoil that has been pushed from the slopes to the west of the drainage that needs to be hauled to the topsoil stockpile. The underdrain will need to be extended up the drainage prior to any refuse being placed up the drainage. An area for the underdrain has been prepared up to a large stands of aspen. There was also a large pile of rock that the operator was moving down for placement in the Phase IB buttress. -The operator was mixing pond cleaning material with dry gob on the RPE. this material was then being hauled to the RPEE(where it is being spread and compacted). The operator was also spreading topsoil on the recently graded slopes of the RPE. This material was being live handled from the drainage above the active lift of the RPEE. Once this work is complete the Division will take several depth measurements to make sure proper soil depth has been placed on the reclaimed slopes of the RPE.
