Spring 2014 Subsidence and Geologic Field Observations <br />South of Divide a d Dry Fork Mining Areas (E -Seam) <br />unidentifiable during the spring 2014 field visit due to weathering, healing and regrading of the <br />road and pad. <br />This traverse includes drill road access to one MDW pad over E -seam Longwall Panel E3 (MDW <br />E3 -29), several pads over E -seam Longwall Panel E4 (MDW E4 -11, E4 -12. E4 -13 and E4 -14) and <br />a large new pad over E -seam Longwall Panel E5 (with no MDWs at that time). <br />The spring 2014 field visit found this area was being used to access and create additional roads <br />and MDW pads over unmined E -seam Longwall Panels E5 and E6. Access to this area was <br />restricted due to this road and pad constn4ction. <br />During the fall 2013 field visit, numerouIs subsidence cracks were observed in the vicinity of the <br />access road to MDW E4 -14 as it climbed out of the Dry Fork drainage to the west (Location 4). <br />At that time, this area was generally above the active longwall mining face. Also observed during <br />the fall 2013 field visit were additional subsidence cracks in the access road to MDW E4 -11 across <br />Dry Fork from the MDW E4 -12 pad (Location 5) and in the cut -slope above the access road where <br />it meets the MDW E4 -11 pad (Location 6). Details about these locations and follow -up <br />observations during our spring 2014 field visit are provided below. <br />4.7.1 Location 4 <br />Location 4 is on, and in the vicinity ofd the access road to MDW E4 -14 (Map 1). Numerous <br />subsidence cracks were observed in this $rea both crossing the access roads to this pad, along the <br />west side of the road leading to MDW E4-413 prior to the turnoff to MDW E4 -14, and on the hillside <br />to the west of the MDW E4 -14 access roadd. Two of these cracks were large enough to block travel <br />to the MDW E4 -14 well pad itself ( Figure 7) with a maximum width and depth of 18 inches and <br />36 inches, respectively. Both cracks could be followed discontinuously to the south onto the <br />hillside with a similar general orientation between the access road and the MDW E4 -14 pad for a <br />distance of about 200 feet. Figure 8 shows the same area as observed during the spring 2014 field <br />visit. <br />831 - 032.795 Wright Water Engineers, Inc. Page 17 <br />September 2014 <br />
