from the two sources provides a method for estimating inflows which cannot
be measured in the mine due to safety constraints. From the meter records
(refer to Table 3) it can be seen that the discharge ranged from 732 to
810 9pm for the period of January 3 to June 25, 1984.
In the prior study three illared areas had be n identified. Those being:
G2 West, 1 left Pane 10, 11 North; ani~6 East. Since that time,
Empire 1 Left Panel and 7 and 8 East Panels have•beeri pillared. Also,
during this study a measurement was obtained from the 2 West 1 left panel
which had been reported as a pillared area in the 198:5 study. However,
the 7 and 8 East panels were dry, and it was not possible to obtain a
measurement from Empire 1 Left Panel._ ~ ~~

Table 3 provides average weekly and year to date discharge in gpm from the
No. 5 Mine for the period January 3 through June 25, 19I34. These data are
generated from the weekly readings of the No. 5 Mine de~watering pumps for
that period.
