Spring 2014 Subsi nce and Geologic Field Observations <br />South of Divide and Dry Fork Mining Areas (E -Seam) <br />Another sub - traverse leaves the main traverse (Dry Fork Road) near the extreme eastern, and <br />mined, end of E -seam Longwall Panel 145. This traverse heads northward to several two MDW <br />pads; one containing MDW E5-1/2/3 andl another containing NOW E5 -4. The E -seam overburden <br />depth in this area is about 1,200 feet. Muting had recently occurred beneath both MDW drill pads <br />at the time of our spring 2014 field visit. The pad containing MDW E5 -1/2/3 showed evidence <br />that it had been the collection point for decent runoff in that desiccation cracks were observed at <br />numerous locations across the pad (Figure 1). Recent regrading around portions of the pad <br />perimeter appeared to have resolved this, issue. Only minor subsidence cracks were observed on <br />the road leading onto the MDW E5 -1/23 pad. Small subsidence cracks were observed on the <br />MDW E54 pad. These cracks were primarily oriented in a north/south direction and observed to <br />have the following maximum dimensions: length - 3 feet, depth — 0.25 inch, and width — 0.25 inch. <br />The MDW E54 pad is depicted in Figui* 2. <br />Figure 1. Spring 2014 image looking south lat the drill pad for MDWs E5- 1/2/3. This area had been mined <br />under recently but showed very little subsid4nce- related evidence. <br />831 - 032.795 Wright Water Engineers, Inc. Page 11 <br />September 2014 <br />
