2.04.7 Hydrology Description <br />Mine inflows in the D -Seam subsided when mining was complete in the down <br />dip portions of the mine and production shifted to the west panels. See the <br />Map 14, D -Seam Mine Plan for timing. <br />The B -Seam hit steadily increasing water inflows in the northeast section of <br />the mine beginning in 2008. The inflow is predominantly from sandstone <br />channels. As of the end of May 2008, the mine inflow was about one million <br />gallons per day ( -700 gpm). Much of the inflow is from sandstone channels <br />around the B -8 panel. As of August 2008 the mine inflow has reduced to <br />about 350 gpm. <br />The northeast section of the mine has been abandoned. Mining to the west <br />has not produced significant inflows. No significant water was encountered <br />in the mains that were developed under Terror Creek. Water inflow into the <br />mine west of Terror Creek is associated with sandstone channels. The <br />pattern of water inflow is one of steadily decreasing flow as the face mines <br />through an area and advances away from it. <br />PR -14 2.04-64- 03/14 <br />
