<br />From the baseline data, all three zones should be classified as 'aquitards' in that they will yield <br />water but at very slow rates. Mining in the D Seam so far has encountered only small flows of water <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, etc., see Plate 1). The quantity <br />and quality of this water is discussed in Section 2.2.2.5. <br />' 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. A <br />description of how these numbers are arrived at follows. <br />1 <br /> <br /> <br />1 <br /> <br /> <br /> <br /> <br />1 <br />1 <br />TABLE 2-3 <br />MINE WATER BALANCE <br />WATER IN GALLONS/YEAR GALLONS/MIN <br />Production Equipment 26,394,000 50.22 <br />Ventilation Humidity 11,216,818 21.34 <br />Seeps 26,026,572 49.52 <br />Incidental (pipe leaks, road) watering, wash down 4,592,925 8.74 <br />.:. <br />TOTAL - `68,230,315 129.81 <br />WAT ROUT <br />Coal Surface Moisture 9,060,547 17.24 <br />Ventilation Humidity 24,736,068 47.06 <br />Pumped Out 34,433,700 65.51 <br />11 <br />1 <br />
