Fall 2017 Subsidence and Geologic Field Observations <br />South of Divide and Dry Fork Mining Areas <br />observed on the pad. The E -seam overburden depth at this location is approximately 850 feet. <br />Figures 14 and 15 show the subject pad during the 2017 spring and fall field visits, respectively. <br />Figure 14. Southward view of the western edge of the MVB E6-12 pad during spring 2017 showing <br />the down -dropped portion of the pad (lower and middle right) in response to differential settlement of <br />the pad as exacerbated by longwall mining beneath the area. <br />Figure 15. Southward view of the same area shown in Figure 14 as observed during the fall 2017 <br />field visit. Notice the smoother and weathered appearance of the slump face. <br />831-032.799 Wright Water Engineers, Inc. Page 22 <br />February 2018 <br />
