Fall 2015 Subsidence and Geologic Field Observations <br />South of Divide and Dry Fork Mining Areas <br />3.15.2 Location 8 <br />During the spring 2015 field visit, WWE observed a well-healed crack in the access road <br />approximately 500 feet southwest of the MVB E5-12/13 pad. This crack manifests itself as an <br />elevation change in the road of approximately 12 inches. Confirmation of this crack was provided <br />by the open feature on the cut slope side of the road at the same location. This cut slope feature <br />was measured to be about 30 inches long, 8 inches wide and about 18 inches deep with an <br />orientation of approximately N75°E (see Figure 14). This location is approximately 200 feet north <br />of the surface projection of the E -Seam Longwall Panel E5 headgate entries. <br />Figure 14. Southward view of well-healed subsidence crack beneath the access road between <br />the MVB E5-12/13 pad and the MVB E5-14 pad. Note the crack extension in the cut slope as <br />further evidence of this relatively recent subsidence feature. <br />Observations made during the fall 2015 field visit found that regrading of the road had significantly <br />reduced the elevation change, thus minimizing the evidence of this feature. The crack in the cut <br />slope, however, was still visible but showing signs of weathering and healing (see Figure 15). <br />831-032.797 Wright Water Engineers, Inc. Page 21 <br />March 2016 <br />
