West Elk Mine <br />MVBs are operated by connecting a mobile, methane -fueled exhauster to the wellhead. Starting in 2020, <br />mobile flaring units will be connected to the mobile exhausters to flare MVB emissions from active <br />and/or sealed longwall panels. These units are typically moved with heavy-duty pickup trucks. <br />Some methane gas from the sealed mine sections is used to heat mine ventilation air at the Ventilation Shafts <br />No. 1 & 2, in a system completed in 2003 and amended a few years later. A 10" diameter methane supply <br />hole was drilled to the B seam to the south of Shaft 3. About 100' of buried 12" HDPE pipeline ties the <br />borehole into the existing mine air heater line. <br />Fire Breaks <br />Fire Breaks are constructed West the Main Mine Site. The neighboring mine, Bear Mine, has historically had <br />issues with underground fire that, more recently, has spread to surface fire. In order to protect the Main Mine <br />Site location and land from fire danger MCC installed a fire break that consists of approximately 1.8 miles of <br />road that is roughly 20-30 feet wide. The land disturbance for the Fire Breaks is not a mine facility and will <br />not be used in the future for any activity associated with mining or reclamation. See Exhibit 83 for Fire Break <br />location. <br />Figure 17: Fire Breaks- located in Exhibit 83 <br />Access Road to Bear Mine Site <br />An access road to the inactive Bear Mine site is located East of MB-5E ponds and extends to the vent holes <br />that have created a fire hazard to the immediate and surrounding areas. MCC is not liable to reclaim this road <br />and the disturbance is not a mine facility and will not be used for any mining activity. See Exhibit 83 for <br />construction, location and use details. <br />Figure 17a: Bear Mine Access Road- located in Exhibit 83 <br />2.05-28 Rev, 06105, 01106, 03106, 04106 & 05106- PR70; 01/09- A4R350: 04/09- TR716; 04/09- AlIR353; 05/09- MR354: 08/09- TR118: <br />08109- TR119: 09/12- MR387: 11/12- MR390; 07118-PR15: 11/18- MR430: AIM& 09119: MR439- 1119: 07120- MR447; 6/2- <br />MR464: 6122 AIR466: 6122 MR468 <br />
