Spring 2017 Subsidence and Geologic Field Observations <br />South of Divide and Dry Fork Mininq Areas <br />Figure 13. Northwestward view of a Figure 14. Southeastward view of a <br />subsidence crack along the access road subsidence crack along the access road <br />between MVB E6-10 and MVB E6-11. between MVB E6-10 and MVB E6-11. <br />4.5.3 Location 9 <br />Location 9 represents a discontinuous set of subsidence cracks located approximately 60 feet east <br />of the MVB E6-11 pad (Figure 15). The maximum dimension of these cracks was about 25 feet <br />in length, 3 inches in width, and 24 inches in depth all with a general orientation of N70°E. The <br />relative location of these cracks is over the intersection between E -Seam Longwall Panel E6 and <br />its headgate entries. The E -seam overburden thickness at this location is about 1,200 feet. <br />831-032.799 Wright Water Engineers, Inc. Page 23 <br />August 2017 <br />
