412 believed to be a function of fracturing. The corresponding hydraulic <br />. conductivity for the Rollins Sandstone was found to range from 0.014 feet per <br />day to 4.34 feet per day. <br />Estimated actual quantities of water removed from the sub-areas of the <br />Roadside North and South Portals in 1994 are tabulated in Table 7-2. Based on <br />this data, approximately 792 acre-feet of water are removed from mine workings <br />annually. These estimates are expected to increase as ventilation volumes <br />increase, production increases and as exposed area increases. <br />i <br />• 7-6b (New 9/17/97) <br />
