Subsidence monument installed after <br />D-Seam was mined. <br /> 33A-331 B-3 Panel 33A Subsided 6.2'. Subsidence monument installed after <br />D-Seam was mined. <br /> 34A-34K B-3 Panel 34-A Subsided 5.3 Subsidence monument installed after <br />D-Seam was mined. 34-B Subsided 6.0'. <br /> 35A-35D B-3 Panel 35-C Subsided 7.6'. Subsidence monument installed after <br />D-Seam was mined. <br /> B-4 Panel No subsidence monuments over B-4. <br /> 8A-8D B-5 Panel 8A - 8D located on the northern edge of B-5 and above 13- <br />6 show a consistent subsidence of about 10.0' <br /> <br />9A <br />B-6 Panel 9A located in the southern edge of B-6 panel subsided 8.2 <br />feet. 6' is attributable to the D Seam. The initial mining in <br />B-6 likely triggered the -7/1/07 Freeman Gulch landslide. <br /> 5C B-7 Panel 5C located in the center of the B-7 panel subsided 10.0' <br /> Surveyed during reporting period. <br />The table shows the B-1 and B-2 panels over the WD panels have added an additional <br />8.6', 7.2', 6.5' and 7.2' feet of subsidence at monuments 25C, 26E, 27B and 28B <br />respectively. <br />-3-
