Introduction This report covers the period from January 2004 through June 2004. Mine Construction of the Bowie No. 2 Mine began during May of 1997, with coal production beginning during August 1997. The mining permit application for the Bowie No. 2 Mine requires the operator to submit the results of the subsidence monitoring programs and the results of the visual inspections of known modern and historic landslides within the permit and adjacent area for stability in June and December of each year and report these results to the Division within 30 days of the ends of the reporting periods. The operator is also required to inspect these landslides, both modern and historic monthly for six months immediately after retreat mining occurs. This same inspection routine is applied to any spring or pond in the immediate proximity of retreat mining. Longwall mining during the period included completion of the D-9 panel and the initiation and completion of mining in the WD1 panel. Mining in the WD2 panel had not begun by the end of the reporting period. Visual Inspection of known historic and modern landslides. A visual inspection of all known historic and modern landslides was conducted during May and June 2004 by J. E. Stover, 2768 Compass Drive, Suite 101, Grand Junction, CO 81506. No new or rejuvenated landslides were found during this inspection. These sites are also regularly inspected by Bowie personnel during gob vent borehole construction and reclamation efforts. Increased Inspection activity associated with retreat mining. Accessible subsidence cracks are repaired during coal exploration events and are monitored by both coal exploration supervisors and hydrologic monitoring technicians. The accessible visual results of the subsidence effects associated with the Bowie No. 2 Mine are overlain on Map 27 - B Subsidence Monitoring. Map 27-B is not enclosed since there are no new subsidence features to depict. During this period, 1 hydrologic monitoring point, S-10, was potentially impacted or re-impacted by mining activities. Potentially impacted or re-impacted means the mine workings or angle of draw of the mine workings passed under the monitoring point during the reporting period. No influence to any of these hydrologic monitoring points were observed during this period. Results of Subsidence Survey Monitoring The results of the May and June 2004 monitoring are attached. As in the past, the survey was performed by Cragg Surveying using GPS methods. Analysis of Subsidence Data The following table presents an analysis of the subsidence survey data. The only activity was over panel W Di ,Stations 28A - 28D. The maximum subsidence in the center of the panel was 5.56'.
