On June 19th, 1986, a complete inflow survey was made in the Eagle No. 5
Mine. Map IV-11, which is attached, has been modified to show the present
sampling points and moisture conditions in the mine. Also, Map IV-11 has
been updated to show the extent of mining since the last study. The way
in which water is handled in the mine is similar to the manner presented
in the prior study, i.e. gravity flow in western parts of the mine and
gravity flow augumented by pumping in the eastern parts of the mine. The
existing sumps continue to be used, which makes it impossible to obtain
readings from the exact locations presented in the prior study. Those
sumps are in the northern and eastern portions of the mine. For example,
the northern sump, which is the main mine sump, has flooded approximately
85 acres, which automatically eliminates this and the adjacent area from
the study.
The survey was conducted by traveling along all of the accessible main
entries and noting the presence of measurable flows of water. Where
submains intersected the mains, the flows from the submains were isolated
and noted on the map. If the flow was substantial, it was traced to its
source unless safety prohibited. As in prior years, t:he largest single
source of water to the No. 5 Mine is from the first trio of three normal
faults encountered in the second west section of the mine. These faults,
plus flow from the west, are prcducing approximately 391 gpm.
