Introduction <br />This report is for the period from January 1, 2014 through June 30, 2014. Mine <br />Construction of the Bowie No. 2 Mine began during May of 1997, with coal production <br />beginning during August 1997. <br />The mining permit application for the Bowie No. 2 Mine requires the operator to submit <br />the results of the subsidence monitoring programs and the results of the visual <br />inspections of known modern and historic landslides within the permit and adjacent area <br />for stability in June and December of each year and report these results to the Division <br />within 30 days of the end of the reporting period. <br />The Operator is also required to inspect these landslides, both modern and historic, <br />monthly for six months immediately after retreat mining occurs. This same inspection <br />routine is applied to any spring or pond in the immediate proximity of retreat mining. <br />During the reporting period, mining was completed in panel B -14 and mining <br />commenced in panel B -15. Panel B -15 is 65% complete with approximately 1,330 feet <br />of the panel remaining to mine. Panel B -16's headgate was completed and the bleeder <br />entry lacked 275 feet of advance to tie into the tailgate. Development in the north mains <br />continued during the period. The north mains have been developed approximately <br />2,300 feet to date. <br />Visual Inspection of known historic and modern landslides. <br />A visual inspection of all known historic and modern landslides was conducted during <br />May 5th and 6th, 2014 by Brad Lindsay, Rock Logic Consulting LLC. Mr. Lindsay's <br />report is attached. Three cracks were observed. The new cracks overlayed the <br />southern portions of B -14 panel. Cracks over the B -10, B -11, D12 and B -13 panels <br />continue to heal. <br />Increased Inspection activity associated with retreat mining. <br />Accessible subsidence cracks are repaired during coal exploration events and are <br />monitored by both coal exploration supervisors and hydrologic monitoring technicians. <br />During the period Spring 7 -10, Pond and Spring 7 -1 and 20 were potentially impacted or <br />re- impacted by Panel 14. Ponds 12 -1, 7 -2, 12 -2 and Pond and Spring 23 were <br />potentially impacted by Panel B -15. Potentially impacted or re- impacted means the <br />mine workings or angle of draw of the mine workings passed under the monitoring point <br />during the reporting period. No influence to any hydrologic monitoring points was <br />observed during this period. <br />Results of Subsidence Survey Monitoring <br />The Pitkin Mesa Pipeline surveys were conducted from January through June. <br />Monitoring points PL -11 and PL -12 which are located over panel 15 showed some slight <br />downward movement. The Terror Creek and Terror Creek transmission line towers <br />survey were performed during June 2014. Monitoring results are attached. As in the <br />past, the survey was performed by Cragg Surveying using GPS methods. <br />-2- <br />
