Fall 2016 Subsidence and Geologic Field Observations <br />South of Divide and Dry Fork Mining Areas <br />readily visible at the surface. The E -seam overburden depth at this location is approximately 1,000 <br />feet. <br />Figure 3. Fall 2016 southward view along the access road to the MVB E6-8\9 pad <br />showing a subsidence crack in the cut slope. <br />4.5.2 Location 3 <br />During the spring 2016 field visit to assess baseline conditions ahead of E -seam longwall mining <br />of Panel E6, cracking associated with differential settlement of the road was observed <br />approximately 500 feet east of the MVB E6-10 pad. Figures 4 and 5 show the extent of the <br />associated cracking on the north side of the road at this location during the spring 2016 field visit. <br />Figures 6 and 7 show the same general area as observed during the fall 2016 field visit. Regrading <br />of the road had eliminated evidence of this differential settlement and there appeared to be no <br />exacerbation of the features in response to recent longwall mining beneath the area. <br />831-032.798 Wright Water Engineers, Inc.
