Spring 2017 Subsidence and Geologic Field Observations <br />South of Divide and Dry Fork Mining Areas <br />9. Subsidence -related effects were observed during the spring 2017 field visit at numerous <br />locations above E -seam Longwall Panel E6 (i.e., MVB pads E6-10 through E6-14, and <br />along some of the access roads between pads). All subsidence -related features were within <br />the expected angle of draw for the E -seam and generally focused in areas of maximum <br />temporary tensile stress, such as above current or recent longwall mining activities. <br />831-032.799 Wright Water Engineers, Inc.
