Spring 2018 Subsidence and Geologic Field Observations <br />South of Divide and Dry Fork Mining Areas <br />9. Subsidence -related effects were observed during the spring 2018 field visit at various <br />locations above recently -mined E -seam Longwall Panel E7 (i.e., from MVB E7-7 to E7- <br />10). All subsidence -related features were within the expected angle of draw for the E -seam <br />and were generally focused in areas of maximum temporary tensile stress, such as above <br />current or recent longwall mining activities. <br />831-032.900 Wright Water Engineers, Inc.
