Spring 2013 Subsidence and Geologic Field Observations <br />South of Divide and Dry Fork Mininq Areas (E -Seam) <br />observed on both pads and along the road near the MDW E4 -10 pad. This sites are discussed below <br />as Locations 1 and 2. <br />Figure 1. Northeastward view during spring 2013 site visit of subsidence cracks likely <br />exacerbated by differential settlement along the largest fill portion of MDW E3 -44 well pad. <br />Another small sub - traverse approximately 250 feet east of point A' leads to the MDW E4 -7 and <br />E4 -8 pads. No subsidence - related features were observed on the MDW E4 -7 pad. Subsidence <br />cracks were observed on the MDW E4 -8 pad and are discussed below as Location 3. <br />4.3.1 Location 1 <br />Several small cracks were observed on the MDW E4 -9 pad and along the crest of the fill slope on <br />the southwestern side of the pad (Figure 2). The maximum dimensions of these cracks were 6 feet <br />long, 0.5 inches wide and 2 inches deep. The E -seam overburden depth at this location is <br />approximately 1,000 feet. The longwall mining face had passed beneath this area a few days prior <br />to our spring 2013 field visit. <br />831 - 032.795 Wright Water Engineers, Inc. Page 11 <br />September 2013 <br />
