• Introduction <br />Mine water inflow results were consistent with the predictions presented in the mining permit <br />application. No apparent measurable mine water inflow was detected during the 2001 <br />underground inspection of the Bowie No. 2 Mine on November 24, 2001. <br />Discharged Water <br />The mine has not dischazged any inflow water from the underground workings nor do the mine <br />portals contribute drainage to the permitted drainage system of the facilities area. <br />Sumps <br />Eight underground sumps were located during this inspection. Mine officials reported that these <br />sumps and their contents were the results of machinery washing and recovered water from belt <br />conveyors where water is applied to allay respirable dust at coal transfer points. <br />These belt line and wash bay sumps held insignificant water and were not tested. <br />Other Water Sources <br />A visual inspection of the lower entry of both the Main North Entries and gate entries of both the <br />D4, DS and D6 longwall panels produced no evidence of any other water sources or storage <br />areas. No significant pooling of water along the travelways or beltlines was found. <br />Consumptive Use <br />• The Bowie No. 2 Mine now extracts dust suppression and sanitary water from the Deer Trail <br />Ditch via the new pump station located on the Deer Trail ditch as shown on Map15-1 of the <br />permit application. During the first months of operation and while the pump station and water <br />line was constructed, water was pumped from this ditch into a water truck, hauled to the portal <br />area and stored in a temporary tank for fire protection and underground dust suppression. <br />Additional water from this source was hauled via the water truck for dust abatement on the mine <br />access roads. <br />The pump station is now fully operable and metered. This meter records the consumptive use of <br />water from the Deer Trail Ditch. During the 2001 calendar year, the Bowie No. 2 Mine <br />consumed 197.11 AC-FT of water in order to produce 5,434,000 tons of coal. Pond evaporation <br />is estimated at 2.0 AC-FT per yeaz. The addition of the estimated pond evaporation to the mine <br />consumption produces a consumptive use of 199.1 I AC-FT of water for the 2001 yeaz and is les< <br />than the estimated 234.6 AC-FT indicated in the permit application. This usage indicates that <br />water for dust suppression and fire prevention at the Bowie No. 2 Mine is currently averaging <br />approximately 36.8 AC-FT per million tons of coal. <br />Conclusions <br />It is reasonable to assume that during the 2001 Mine Water Inflow study season, less than 10 <br />gallons per minute are flowing into the mine workings of the Bowie No. 2 Mine, that <br />approximately 120 gallons of water per minute is introduced from the Deer Trail Ditch and that <br />any sudden increase in mine inflow values could be reasonable incorporated into the dust <br />suppression process, precluding the necessity for any mine discharges. <br />
