1.4 Recent Study
During the week of June 24th 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. Also, since the prior study additional
