MINE INFLOW STUDY <br /> In August, 1989 a mine inflow study was conducted to <br /> determine the quantity and quality of water flowing into the mines. <br /> No new point sources were identified at the New Elk Mine during the <br /> 1989 survey. Four existing points were eliminated and nine new <br /> points were identified in recently mined areas at the Golden Eagle <br /> Mine. Areas which were examined included all active and inactive <br /> underground mine workings. Figures 1 and 2 present the mapping <br /> results of each point source inflow (faults, fractured roof, <br /> fractured floor, exploration drill hole, etc. ) and each area wide <br /> inflow (drainage from seals to abandoned mine workings; areas of <br /> weeping coal faces, roof, or floors; unsealed mine areas; etc. ) <br /> that were encountered during the survey. <br /> GOLDEN EAGLE MINE <br /> At the Golden Eagle Mine (Figure 1) , twenty-eight sources <br /> have been identified in the 1989 mine inflow survey. Table 1 <br /> presents the location, probable water source and estimated gallons <br /> per minute (gpm) for each of these sources. Major sources were <br /> measured volumetrically while seepage and weeping faces were <br /> estimated. A total of 176 gpm inflow was estimated, of which 160. 0 <br /> is routed to the discharge pumps. This relates to 163 gpm measured <br /> and 160 gpm discharged during the 1988 survey. Approximately 110 , <br /> gpm is related to the fault system encountered during early 1988 <br /> while 27 . 5 gpm is from the air shafts, the slope and drill holes <br /> (sources 2 , 6, 7, 8 , 9, 12 , 14 , 15 and 28) and the remainder is <br />
