20 March 2018 C-1981-010/Trapper Mine RAR <br /> <br /> <br />Number of Partial Inspection this Fiscal Year: 8 <br />Number of Complete Inspections this Fiscal Year: 3 <br /> <br /> Page 2 of 6 <br /> <br />This was a complete inspection of the Trapper Mine; C1981010, operated by Trapper Mining <br />Inc. The inspection was conducted and the report prepared by me, Robin Reilley of the DRMS. <br />Graham Roberts, Trapper Mine representative was present throughout the inspection. Skies were <br />clear and temperatures ranged from 32 to 60 degrees Fahrenheit. A blast was observed. As <br />some roads were soft due to warming temperatures portions of the site to be inaccessible. Staff <br />was observed setting up for a drone flight at east end of the site just west of the Deacon Jeffway <br />ditch. <br /> <br /> <br />MAINTENANCE ITEMS: Ponds and Culverts <br />Outstanding maintenance items related to culverts SA7, SA4A, SA2, AE11were discussed. The <br />culverts in question were visited but due to still frozen conditions in the watersheds the culverts <br />held ice at the discharge ends, making it difficult to verify how the culvert lining material is <br />functioning. A future inspection will verify outstanding maintenance issues. All ponds observed <br />appeared to be functioning adequately. <br /> <br />INSPECTION: <br />GENERAL MINE PLAN COMPLIANCE: <br /> <br /> Photo 1: Looking west over area to be mined as N pit. The Craig station is visible in the background. <br /> <br />Main haul roads were dry. At the time of inspection the spoil was being cast, coal was being <br />excavated and hauled; ash was being hauled and over-burden was being loaded, transported and <br />placed in benches. One dragline, the Baby Doe was operating casting spoil. The two other <br />draglines were idle at the time of inspection. Located against the Deacon Jeffway Ditch, the <br />eastern stripping boundary was observed; TMI is ready to excavate coal in this area. The ditch <br />was inaccessible today due to road conditions. The 2018 stripping boundary requires expansion <br />to the east. An overburden blast was observed. No offsite hydrologic or air quality issues were <br />observed at the time of inspection. <br /> <br />SIGNS AND MARKERS Rule 4.02 <br />o Topsoil stockpiles observed were clearly marked with identifying signs.
