Both the Eagle No. 5 and No. 9 Mines require the discharging of mine waters to prevent flooding of the mine workings. The discharge rates of mine waters to the surface have been monitored. Based on hydrographs of mine discharge rates (Figures III-17h and 17i in the application), the applicant projects that the present approximate inflow rate to the Eagle No. 5 Mine is 830 gpm (1.85 cfs) and to the Eagle No. 9 Mine is 250 gpm (0.56 cfs). These rates of inflow will increase as mine workings are expanded in each of the mines. Empire Energy Corporation has calculated the pro3ected mine inflow rates over the 5-year permit period for both the Eagle No. 5 and No. 9 Mines. The projections are contained on Table II-20d, page II-74b. The applicant used values for transmissivity, permeability and storativity for coals obtained from the Northern Coal Company mines, Rienau No. 1 and No. 2. An average value of 225 gpd/ft for transmissivity, 19 gpd/ft2 for permeability and 0.002 for storativity were used in inflow calculations for the "F" and "P" coal seams. These figures seem to be representative of the "F" and "P" seams, and approximate values obtained for the coal seams at the Trapper Mine. The sources of mine inflows were tabulated (see Appendix II-Sb and Map IV-11 in the application for the Eagle No. 5 Mine). Identified sources of mine inflows to the No. 5 Mine were faults, pillared areas (areas subsided), and weeping coal faces. The major source of mine inflows are from faults. Two of three normal faults in the 2 West Mains produced 363 gpm. These two faults are located 125 feet below the Yampa River and approximately 3,600 feet from the center of the river channel on a line parallel to the fault trace. One smaller fault inflow produced 8 gpm. The total inflows from pillared areas and entry areas were 152 gpm throughout the mine. Pillared areas adjacent to the Yampa River in the 2W-ll area produced 30 gpm and represented the highest inflow from a subsided area. Coal mine faces were assumed to account for the remaining 305 gpm. An inflow study was also conducted for the Eagle No. 9 Mine (Appendix III-Bc and Map IV-lla in the application). Mine discharges at the time of the study were 279 gpm in 81 acres, or 2.70 gpm/affected acre. This mine receives inflows from both overlying and underlying strata. About BOX of the Eagle No. 9 Mine inflows is through faults, fractures, roof drips and floor seeps, while the remaining 2090 comes from weeping coal faces on the northernmost mains. The rates of inflow are highest in fault zones and areas beneath Big Bottom, adjacent to the Yampa River. The highest inflow was 61 gpm from a small fault in the 1 West Belt Entry. Not all faults produce inflows. Faults in updip areas which are not overlain by the stream/alluvial system are dry or produce sporadic minor inflows.
