Spring 2018 Subsidence and Geologic Field Observations <br />South of Divide and Dry Fork Mining Areas <br />Figure 6. Eastward view from the spring 2018 field visit of a wide subsidence crack <br />located north of the pump trailer on E7-8 MVB pad, which appeared after longwall mining <br />passed beneath the area. <br />4.5 Traverse E -E' <br />This traverse begins at Traverse A -A • con0m:Qs s6uthward to an intersection with Traverse F- <br />F and then west and south above mined E -seam Longwall Panels E5, E6, and E7 (see Map 1). <br />Overburden along this traverse varies from about 900 to 1,020 feet. <br />Traverse E -E previously allowed access to MVBs E5-9/10 through E5-13/14 above mined E -seam <br />Longwall Panel E5 (now all reclaimed except E5-11 adjacent to the road) as well as access to <br />MVBs E6-8/9 through E6-11 (see Map 1) above mined E -seam Longwall Panel E6 and to MVBs <br />E7-5 through E7-7 above mined E -seam Longwall Panel E7. <br />During the fall 2016 field visit, a subsidence crack was observed in the cut slope along the access <br />road near the MVB E6-8/9 pad.
