Currently, the pumps in the two de-gas holes are not being <br />run and all water being released by the fault is flowing into the <br />mine and being pumped to the surface. The present inflow is <br />calculated at 150 gpm. When the de-gas holes are shut off, there <br />is an immediate increase in gas and water in the mine workings. <br />An exploration hole (GE 32-88), drilled 100 feet ahead of. <br />the fault contact, encountered little gas or water in the Maxwell <br />seam, indicating that the fault structure could be less than 100 <br />feet wide. No surface expression of the fracture system has been <br />found by field observation or on any maps and it is believed that <br />the system was formed before the unconformity in deposition <br />believed to exist above the overlying Red Seam (approximately 100 <br />ft above the Maxwell seam). Other earlier exploration holes, <br />east of the fault zone, have no anomalous indications of water <br />and gas bearing fracture systems. <br />In conclusion, evaluation of the data indicates that the • <br />water inflow has occurred because mine workings connected a fault <br />system that has no surface contact but is in contact with <br />deep-seated connate water under artesian head, which will <br />progressively reduce by draining into the mine and/or being <br />pumped from de-watering holes. The analyses of water and the <br />decreasing flow pattern indicate no effect on surface hydrology <br />from this inflow and there is no reason to believe that further <br />contact with the fault would change that opinion. <br />1 <br />2.04-6(n (Revised 09/01/89) <br />
