An example computation is provided for the <br /> projected mine using the data for Case III. The results of all computations <br /> are summarized in Table 4. <br /> Example <br /> B = ( (1 .27) (225)) 1/2 = 1166 ft. <br /> �f 0.00021 ) <br /> q = (1 .27) (225) = 0.245 ft2/d <br /> 1166 <br /> Inflow from face = (0.245) (4.6x104) = 1 .13x104ft3/d = 59 gpm <br /> Inflow from roof = (2.1x10-4) (l .lx108) = 2.31x104ft3/d = 120 gpm <br /> Total Inflow = 59 + 120 = 179 gpm <br /> Table 4 Summary of Maxwell Mine Inflow Calculations <br /> Current Mine Projected Mine <br /> Roof Face Total Roof Face Total <br /> qpm qpm gpm gpm gpm gpm <br /> Case I 2 7 9 120 39 159 <br /> Case II 2 14 16 120 73 193 <br /> Case III 2 11 13 120 59 179 <br />
