Fall 2015 Subsidence and Geologic Field Observations <br />South of Divide and Dry Fork Mining Areas <br />3.6.1 Location 1 <br />Location 1 is on, and in the near vicinity of, the MVB E5-16 pad (Map 1). Several subsidence <br />cracks were observed in this area beginning in spring 2015, both crossing the access road to this <br />pad and on the pad, itself These features were likely created as a result of the longwall mining <br />face passing beneath this area approximately one month prior to our spring 2015 field visit. <br />During the spring 2015 field visit, three subparallel cracks were observed crossing the northern <br />portion of this large pad with a N50°E orientation. The longest of these discontinuous cracks <br />covered a distance of 80 feet with a maximum width of 16 inches and depth of 36 inches. Fall <br />2015 observations were able to locate these same cracks but with some difficulty in places due to <br />weathering and healing. The maximum dimensions observed during the fall 2015 field visit were <br />about 8 inches wide and 22 inches deep. No evidence of these cracks was observed above the <br />access road or below the pad fill area. E -seam overburden depth at this location is approximately <br />800 feet. <br />Figure 1.
