Mayo and Associates, LC <br />~~ <br />~~ <br />I~ <br />I <br />In July 2003 an exploratory horizontal borehole HDH 16 penetrated the 14 HG Fault <br />about 2,000 feet south of 22HG XC32. The 14HG Fault was crossed in 22HG XC 32 <br />during mined development work the 22 HG in August 2003. Groundwater inflow was <br />100 gpm and declined to 35. <br />Each of the fault-related groundwater inflows is the result of pressure release from <br />hydraulically distinct groundwater system associated with individual fault-related damage <br />zones (Mayo and Associates. 1998; Mayo and Koontz, 2000). The pazallel damage zones <br />are about 2,000 feet apart. The general absence of grotu~dwater inflows from the coal <br />seams or mudstone overlying the B Seam indicate that the Rollins Sandstone waters aze <br />not in hydraulic communication with coal seams Located above the B Seam. <br />Evaluation of Potential Groundwater Inflows 56 <br />Associated witL E Seam Mining, <br />West Elk Mine, Somerset, Colorado <br />February 24, 2004 <br />
