survey of the subsidence over the west D-Seam longwall panels after all three panels <br />were complete and the subsidence attributable to panels B-1, B2 and B3. There were <br />only a few subsidence monuments over the B-4 and B-5 panels. <br /> <br />Station General Location Result <br />7A - 7C Hubbard Creek No significant change <br />17A -17F Hubbard Creek No significant change <br /> D4 Headgate and Mining complete. Maximum subsidence 2.2' over D4 <br />1A-1J North Mains head ate 1 A <br />23A - 23C Mouth of Dove Gulch No significant change <br />24A - 24G West Submains Mining complete. Maximum subsidence 7.5' (24G) <br /> WD1 8~ 61 <br /> Mining complete. D-Seam max subsidence 5.7' (25C) <br />25A - 25F WD2 Panel & 62 Panel B-Seam max subsidence 14.1 25C <br />26A - 26G WD1 Panel & 61 Panel Mining complete. Maximum subsidence 4.7' (26E) <br /> B-Seam max subsidence 11.8' (26E) <br />27A - 27D WD2 Panel & B2 Panel Mining complete. Maximum subsidence 4.0' (27B) <br /> B-Seam max subsidence 10.8' (27B) <br />28A - 28D WD1 Panel & B1 Mining complete. Maximum subsidence 6.2' (286) <br /> B-Seam max subsidence 12.8' (28B) <br />29A - 29D WD2 Panel Outcrop 29A has subsided 1.7' <br />30A - 30D ~ WD Panels Outcrop No significant change <br />31 A - 31 C D1 Tailgate No significant change <br /> 32G Subsided 7.2'. Subsidence monument installed after <br />32A-32M B-2 Panel D-Seam was mined. <br /> 33A Subsided 6.0'. Subsidence monument installed after <br />33A-331 B-3 Panel D-Seam was mined. <br /> 34-A Subsided 5.0 Subsidence monument installed after <br />34A-34K B-3 Panel D-Seam was mined. 34-B Subsided 5.8'. <br /> 35-C Subsided 7.2'. Subsidence monument installed after <br />35A-35D B-3 Panel D-Seam was mined. <br /> B-4 Panel No subsidence monuments over D-4. <br /> 8D located on the northern edge of B-5 Panel subsided <br />8D B-5 Panel 4.5'. <br /> No subsidence monuments over the mining that has <br /> B-6 Panel occurred during the period. The initial mining in B-6 likely <br /> tri ered the -7/1/07 Freeman Gulch landslide. <br />The table shows the B-1 and B-2 panels over the WD panels have added an additional <br />8.4', 7.1', 6.8' and 6.6' feet of subsidence at monuments 25C, 26E, 27B and 28B <br />respectively. <br /> <br />
