the folding of the northwest plunging anticline located <br />,• southwest of the mine. The F seam is downdropped about <br /> 18 feet," (more recent investigation indicates that the <br />displacement is on the order of 33 feet), "on the <br />southwest side of the fault. Normally occurring drag <br />features were seen in a soft clay fault gouge within <br />the nearly vertical fault zone. A large volume of <br />water was issuing from open fractures associated with <br />this zone. Mine engineers had previously installed a <br />device to monitor water volume at this location and <br />have measured a decreasing flow over the past few <br />months. Strike direction of the major fracture sets <br />are parallel to the fault and the anticlinal fold axis. <br />(• "One day of the trip was used to study fractures along <br />surface outcrops of the Williams Fork formation of the <br />Eagle No. 5 coal mine property. A total of 225 dip and <br />dip azimuth measurements were recorded using a Cocla <br />'Stratum' compass. Extent and spacing measurements <br />were also noted. Fracture orientation were plotted in <br />the office on an upper hemisphere Schmidt Stereo Net. <br />Results of this work supported observations made underground <br />with the exception that the north-south features seen <br />underground were <br />north 30° west s <br />sample whereas a <br />Dips were nearly <br />\_ <br />north.
