Kerr - Pum_n Test Results <br />12/21/79 <br />Page Two <br />The second test on well 028-79-19 :vas a drawdown test of the <br />siltstone layers lU0 feet benea <br />79-16 and 79-60 for observation <br />of these saturated rocks is 3.9 <br />These numbers indicate very low <br />well was only 20 feet away from <br />~h th_ ell <br />Graoh ~4 <br />ft2/day an <br />permeabiii <br />the oumoed <br />seam, using wells 02~-79-15, <br />shown that transmissivit~ <br />3,nermeability is 0.0? ft/day. <br />~y., The closest observation <br />well and di3 not react to <br />the test. Since the observation wells were finished in the ccal seam, <br />the saturated rocks underlying the coal seam must be confined b-: shale <br />layers and groundwater cannot .flo:v to or from the coal seam to the <br />rocks below. <br />In conclusion, the Sudduth coal seam is saturated and perneable <br />in the 22777 lease area, but it is confined above and below by shale <br />• layers. The rocks above the coal seam are apparently dry. The faults <br />encountered during the drilling program act as barriers to groundwater <br />flow. Therefore, when the pits are opened in the lease area, the <br />only groundwater aquifer to contend with will be the coal seam itself. <br />The east highwalls will be dry and the west highwalls should not <br />release water to the nit. Sums in the pit will be needed since <br />mining will dewater the coal aquifer. The water in the pits may have <br />to be Dumped continuously. More data is needed from the U.S.G.S., <br />and another pump test in the northern part of the lease area may be <br />needed to determine the rate and amount of water inflow to be handled. <br />G ~~- <br />GPSaunders <br /> <br />
