Fall 2014 Subsidence and Geologic Field Observations <br />South of Divide and Dry Fork Mining Areas <br />At the time of our fall 2014 field visit, this feature was again observed. The overall length was <br />about 150 feet with no evidence of extension across the access road (southeast corner of pad) or <br />further west away from the pad. Observed maximum dimensions included 2 feet in width and 3 <br />feet in vertical drop from one side of to the other. Longwall mining beneath this area 1 -2 months <br />prior to our fall 2014 field visit appeared to have somewhat exacerbated this slope movement, <br />however, no other evidence of this landslide phenomenon could be detected. <br />This feature is located about midway between the headgate and tailgate entries of E -seam Longwall <br />Panel E5 where there is about 1,100 feet of E -seam overburden. <br />Figure 11. Southwestward view of mass - gravity movement feature on the cutslope south of the <br />MDW E5 -9/10 pad. The feature is located at the transition from vegetation to unconsolidated fill <br />material (bare ground). No subsidence - related features were noted on this pad. <br />3.15.2 Location 4 <br />Several small subsidence cracks were noted along the road west of the MDW E5 -11 pad near the <br />access gate (see Figure 12). Additional cracks were observed further west at the intersection with <br />another road heading further south. Observed cracks were discontinuous across about 20 feet of <br />road width with no evidence of extension into the cutbank or fill slope adjacent to the road. <br />Maximum crack dimensions were 0.25- inches wide and deep. This area was directly above the <br />active longwall mining face at the time of our fall 2014 field visit. These cracks are located about <br />831 - 032.796 Wright Water Engineers, Inc.
