Spring 2017 Subsidence and Geologic Field Observations <br />South of Divide and Dry Fork Mining Areas <br />Figure 16. Spring 2017 southeastward view of several subsidence cracks on the MVB E6-11 pad. <br />The best visual evidence of the cracks is in the lower left portion of the image. These cracks extend <br />discontinuously from the lower left to the southwest corner of the pad (i.e., toward the soil stockpile <br />in the upper middle portion of the image). <br />4.6 Traverse F -F <br />Traverse F- ) • D O O R Z V abovDmFneff EHeaVi B6ngwaWaBel E5, Qs 9,,eWoasV <br />access to E6-1/2/3 through E6-7 (see Map 1) above mined E -seam Longwall Panel E6 and what <br />will likely be the eastern -most MVB pads over E -seam Longwall Panel E7. The E -seam <br />overburden depth along this traverse is from 1,000 feet to more than 1,200 feet. <br />No obvious subsidence -related features were observed during our spring 2017 field visit. <br />Construction work was underway further to the south over E -seam Longwall Panel E7. Baseline <br />observations were made at what will likely be referenced as MVB E7-1, although the site was <br />occupied at the time by equipment.
