Fall 2019 Subsidence and Geologic Field Observations <br /> Southern Panels Mining Area <br /> 9. Subsidence-related effects were observed during the fall 2019 field visit at various <br /> locations above recently mined E-seam Longwall Panel E7 (i.e., on the access road south <br /> of MVB E7-12 [Location 1] and on the access road south of E6-14[Location 2]) and mined <br /> E-seam Longwall Panel E8 (i.e., at MVB pad E8-6 [Location 3], at MVB pad E8-7 <br /> [Location 4], questionably at MVB pad E8-5 [Location 5], at the intersection of roads <br /> leading to MVB E8-7 and E8-8 [Location 6], at MVB pad E8-3 [Location 7], and at MVB <br /> pad E84 [Location 8]). All subsidence-related features were within the expected angle of <br /> draw for the E-seam and were generally focused in areas of maximum temporary tensile <br /> stress, such as above current or recent longwall mining activities. <br /> 831-032.910 Wright Water Engineers, Inc.
