Fall 2014 Subsidence and Geologic Field Observations <br />South of Divide and Dry Fork Mining Areas <br />Figure 9. Example crack in brittle sandstone outcrop at Photographic Observation Point 5 that <br />occurred as a result of the mining of E -seam Longwall Panel E4 beneath this area. <br />3.15 Traverse J -J' <br />This is the fourth of four named traverses that originate from Traverse C -C'. This traverse allows <br />access to MDWs E5 -08 through and E5 -14. Several of the MDW pads (E5 -08 through E5 -11) <br />have been visited for baseline observation since spring 2013. As of the time of the fall 2014 field <br />visit, the longwall mining face was beneath MDW E5 -11. A relatively continuous feature was <br />observed on the south side of the cut slope located above the MDW E5 -9/10 pad. This feature was <br />first noted during the spring 2014 field visit and prior to longwall mining beneath this area <br />suggesting no connection to subsurface activities. This feature is discussed below as Location 3. <br />Small subsidence cracks were noted on the road near the access gate between the MDW E5 -11 <br />pad and the MDW E5 -12/13 pad. These cracks are discussed below as Location 4. No subsidence <br />features were noted on the MDW E5 -8 or MDW E5 -11 pads above mined E -seam Longwall Panel <br />E5. Visits to the MDW E5 -12/13 and E5 -14 pads were baseline visits prior to any mining <br />activities. <br />831 - 032.796 Wright Water Engineers, Inc. Page 18 <br />March 2015 <br />
