Spring 2014 Subsidence and Geologic Field Observations <br />South of Divide and Dry Fork Mining Areas (E -Seam) <br />Figure 2. Spring 2014 image looking west/northwest at the drill pad for MDW E5 -4. The observed subsidence <br />cracks were located on the pad near the fence enclosure. <br />4.3.1 Location 1 <br />Three prominent sub - parallel subsidence cracks were observed at this location on the northwest <br />corner of the MDW E4 -8 pad each with a general north -south orientation. Maximum dimensions <br />on these cracks included 1.25 inches in width and 8 inches in depth. Two of the cracks were within <br />the level portion of the pad (Figure 3) while the third was located on the crest of the loose berm <br />material at the edge of the pad. Weathered remnants of these cracks were present at the time of <br />our spring 2014 field visit (Figure 4). Differential settlement was apparent along the outside edge <br />of the pad where arcuate - shaped cracks were evident (some up to 5 inches wide and 8 inches deep). <br />Longwall mining occurred beneath this location in late March 2013 (prior to our spring 2013 field <br />visit). The E -seam overburden depth at this location is approximately 1,050 feet. <br />831 - 032.795 Wright Water Engineers, Inc. Page 12 <br />September 2014 <br />
