• Mine water importation is estimated from recorded flows and related tonnages at the <br />Mine from September of 1985 through April 1986. Calculations from recorded <br />measurements indicated approximately 2.5% by weight of imported water (in <br />relationship to the total raw coal tonnage) is used for face and roadway dust control. <br />This translate to an import water usage of approximately 3,200,000 gallons from <br />July, 1995 through June, 1996. <br />From historical detailed coal sampling at the face and on the surface, an <br />approximate 1 % moistwe gain from the in-place value to the train loadout point is <br />apparent. Consequently, approximately 1,275,000 gallons of water were imported <br />for face coal dust control. Therefore, approximately 1,925,000 gallons of water <br />were used for roadway dust control with a small percentage of this evaporating as <br />humidity into the air and being expelled from the mine. <br />I-I~drologic Impacts: <br />There was virtually no water inflow into the mine. Therefore, the hydrologic impact <br />caused by the mining operation is either non-existent or not measurable. <br />Conclusions• <br />Mine inflow into the Bowie No. 1 Mine continues to be low. The present estimated <br />inflow rate remains at less than 1,000,000 gallons anmially. The importation of <br />water continues to far exceed the occurrence of natural mine inflows. No mine <br />discharge is anticipated during the 1996 - 1997 reporting period. Therefore, the <br />quality and quantity of surface water adjacent to the West Mine will not be affected. <br />The operator will continue to submit the Annual Subsidence and Hydrology Report <br />which will summarize all subsidence and hydrology data. This study is part of that <br />annual report. <br /> <br />Page -4- <br />
