these two sealed gate roads is the water pumped into the area earlier in the year, working its way <br />down gradient to these two low points in the mine. <br />During 2006, the two seals noted above plus a third seal located in 4 West and 5 West panel gob <br />flowed a combined 17.2 gpm. All flows are collected and eventually routed to the mine sump. <br />In addition, a large perched, but temporary, water zone flowed in the west end of 10 West and <br />flowed into the gate road. It was also collected and pumped to the mine sump. By the end of <br />2006, the 10 west water flow had greatly diminished to where the entire flow is now pumped just <br />10 minutes a day to D2B2. <br />During 2007, a similar perched zone flowed temporarily in the west end of 11 West and pumped <br />to the mine sump. By the end of 2007, the 11 West water flow had greatly diminished. The 4 <br />West and 5 West seals still flow... 17.0 gpm. <br />During 2008 the 4 West and 5 West still flow at the same — 17.0gpm. Little other unusual <br />perched water zones were encountered. <br />During 2009 the 4 West and 5 West seals flow a combined 11.25 gpm. When measured in <br />October, 2009 the new Bear Creek Shaft produced —4.6 gpm, but later flow was reduced to 1.25 <br />gpm by early 2010. The 13 West entry #1 seal flowed —110 gpm. <br />During 2010, the 4 West and 5 West seals flowed at a combined rate of 8.96 gpm. The 13 west <br />entryl seal flowed — 72.86 gpm. A fracture was encountered at 4 North, entry 1, 14.75 crosscut <br />which initially generated substantial water. By fall, the flow has diminished to 103.8 gpm. <br />During 2011, the 4 West and 5 West seals flowed at a combined rate of 11.70 gpm. The 13 west <br />entryl seal flowed — 83.00 gpm. A fracture encountered at 4 North, entry 1, 14.75 crosscut <br />which initially generated substantial water is no longer flowing. <br />During 2012, the 4 West and 5 West seals flowed at a combined rate of 12.3 gpm The 13 west <br />entry 1 seal flowed —80 gpm. The 4B entry 10.5 crosscut flowed 2.69 gpm. The 4N entry, 3 E <br />crosscut flowed 23.08 gpm. <br />See the D2B and D2B2 well discussion above for information regarding the transfer of collected <br />Elk Creek mine sump water to the abandoned Somerset B/C seam workings. <br />Otherwise, the groundwater encountered in the mine is fairly minimal and randomly distributed. <br />Perched water bearing zones are sometimes encountered (as expected) with significant initial <br />flows, but they seem to dewater fairly quickly. <br />Outfall 011 — Sanborn Creek Mine Water Discharge <br />Outfall 011 was the OMLLC - CDPS mine water discharge point from Sanborn Creek Mine that <br />discharged into Sanborn Creek <br />The Sanborn Creek Mine water drainage system was decommissioned on May 21, 2003. Since <br />the mine completed the last panel, the underground hardware was removed and the entries were <br />sealed in accordance with MSHA requirements. <br />17 <br />
