1 <br />and the mine is essentially dry. Water leaking out of caved areas is routed to the sumps at the end <br />of gateroads. From there it is pumped to the surface through a borehole and discharged. The <br />' boreholes are designated as sump dewatering holes (SDH2, SDH3, SDH5, etc., see Plate 1). The <br />quantity and quality of this water is discussed in Section 2.2.2.5. <br />1 2.2.2.4 Bedrock Water Ouallty Water sampling and analysis are no longer required from the <br />bedrock monitoring holes. However, prior to entering Federal leases C-8424 and C-8425, one <br />water quality sample will be collected and analyzed from each of the monitoring holes in those two <br />leases. <br />' The Deserado Mine First Annual Hydrology Report (December 1985) contains baseline water quality <br />data for the bedrock zones. <br />' 2.2.2.5 Mlne Water Balance Table 2-3 shows the water balance for the Deserado Mine. The total <br />' water quantity in the water balance decreased by about 19 million gallons since water was not <br />pumped from SDH2 during this water year. The SDH2 sump serves longwall panels one through <br />five (LW1-LWS) and this disVict (District 1) has been sealed and is no longer accessible. Pumping <br />' will resume in late 1994 to keep the water level to an acceptable point in District 1. A description <br />of how these numbers are arrived at follows. <br /> <br /> <br />1 <br /> <br /> <br />1 <br />1 <br /> <br />1 <br />TABLE 2-3 <br />MINE WATER BALANCE <br />WATER IN GALLONS/YEAR GALLONS/MIN <br />Production Equipment 27,224,400 51.80 <br />Ventilation Humidity 11,216,818 21.34 <br />Seeps 5,727,513 10.90 <br />Incidental (pipe leaks, road) watering, wash down 4,822,571 9.18 <br />-_ <br />TOTAL 48,991,302 -_ 93.21 <br />WATER OUT <br />Coal Surface Moisture 9,814,964 18.67 <br />Ventilation Humidity 24,736,068 47.06 <br />Pumped Out 14,440,270 _ 27.47 <br />11 <br />1 <br />
