March 8, 2012 C- 1980- 007/West Elk Mine JRS <br />HYDROLOGIC BALANCE (cont.) - Freshwater pond FW -1 contained water approximately three feet below the <br />top. The mine has been drawing down this pond for use in mining - related activities. Pond FW -2 was full at the <br />time of the inspection. Both pond embankments were covered with snow but appeared to be stable. <br />- All of the roadside ditches along the mine entrance road, the Sylvester Gulch road and around the coal stockpile <br />areas contained snow but appeared to be working as designed. There was visible flow in some of the ditches and <br />no flow was observed outside of any of the ditches. <br />- Pond SG -1 was covered with snow but appeared to contain water approximately five feet below the primary <br />spillway. The pond was not discharging at the time of the inspection. The pond embankment appeared to be <br />stable and no erosional problems were noted. <br />- The mine water treatment ponds in Sylvester Gulch contained water approximately 10 feet below the top and <br />were not discharging. The pond embankments were covered with snow but appeared to be stable. No erosional <br />problems were noted. <br />GENERAL MINE PLAN COMPLANCE: <br />- The operator was mining in E -Seam in longwall panel LWE -3. They were at approximately cross -cut 45 (which <br />has advanced from cross -cut 47 last inspection). The development mining was working in the panel LWE -4 <br />headgate and was at approximately cross -cut 77 (which has advanced from cross -cut 70 last inspection). <br />Development work in the panel LWE -5 headgate is still at approximately cross -cut 5. Finally, Mountain Coal has <br />developed the south mains to the beginning of the panel LWE -6 headgate (which has not advanced since the last <br />inspection). All of the mining and development was on the current operations map in the basement of the main <br />office building. This information matches the mining sequence shown on approved Map 51 - E -Seam Projected <br />Operations (last updated on 14 February 2011 with the approval of Technical Revision 124. <br />PROCESSING WASTE /COAL MINE WASTE PILES — Rule 4.10 and 4.11 Drainage Control; Surface <br />Stabilization; Placement: <br />- The operator was moving refuse from the stockpile on the RPE and spreading and compacting it on the pile. <br />There is still a very large pile of refuse stockpiled on the RPE that needs to be spread and compacted. The pile <br />appears to be well graded, with positive drainage and no water pooling on the surface of the pile. The reclaimed <br />outslopes of the pile were covered with snow but appeared to be stable, with no erosional problems noted. The <br />perimeter ditches were clean and water was flowing in the ditches. <br />- The operator was producing refuse and was hauling it to the RPEE with articulated trucks at the time of the <br />inspection (they have been hauling refuse to the RPEE for approximately a week). They were end dumping the <br />refuse in the hole that was excavated behind the colluvial fill. They are spreading and compacting this refuse with <br />a D6 dozer which, based on size limitations, spreads the refuse in approximately six inch lifts. They are <br />performing compaction testing as they go and, according to Mike Peacock, they are meeting all of their <br />compaction requirements. The area was a little sloppy and muddy due to the melting snow and there was an <br />excavator stuck in the refuse. The operator indicated that, once they got the excavator out, they would rework the <br />top portion of the pile as necessary. The current underdrain for the pile goes approximately 25 feet up the <br />drainage and will be extended farther up the drainage as more refuse is placed on the pile and the pile advances. <br />Number of Partial Inspection this Fiscal Year: 9 <br />Number of Complete Inspections this Fiscal Year: 3 <br />Page 3 of 8 <br />
