Spring 2017 Subsidence and Geologic Field Observations <br />South of Divide and Dry Fork Mining Areas <br />f �- <br />Figure 8. Northwestward view of a subsidence <br />crack on the MVB E6-14 pad. Note the small <br />graben -like structure in the right foreground <br />where materials between two cracks have <br />fallen. <br />4.4 Traverse D -D' <br />Figure 9. Southeastward view of the same <br />subsidence crack shown in Figure 8. Note the <br />continuation of the crack across the pad and <br />onto the soil stockpile. <br />This traverse originates along the south side of the Dry Fork Road (Traverse A -A • D Q G <br />southward up Poison Gulch (drainage east of Deer Creek) to a location above the headgate entries <br />above unmined E -seam Longwall Panel E7. This traverse crosses mined portions of E -seam <br />Longwall Panels E3, E4, E5, and E6, as well as unmined portions of E -seam Longwall Panel E7 <br />(see Map 1). The E -seam overburden depth along this traverse varies from slightly less than 700 <br />feet to almost 900 feet. <br />The portion of this traverse south of Dry Fork currently provides access to three MVB pads above <br />E -seam Longwall Panels E5 and E6 (i.e., E5-15, E5-16, and E6-12).
