A comparison of tables 2 and 3 indicates that some of the mine inflow can not be measured directly. If one compares the total of the measured flows against the average year to date reading of June 25 it is seen that 181 gpm can not be measured. Again, It is assumed that this flow is associated with flooded and sealed areas of the mine. 1.6 Conclusions The study reveals that conditions within the mine are remaining essentially the same as during the prior year. That is the eastern portion of the mine is relatively dry, while the western portion of the mine produces the majority of the inflow. The major sources are the faults and 2 West, 1 Left Panel. The fault system produces water at approximately the same rate as measured during the previous year. The data indicates that tF~e inflow from the fault zone has not changed since May, 1983. This iindicates that the aquifer(s) supplying the fault has reached steady-state conditions. The relatively high temperature of the water issuing from t:he fault indicates that the source of the water is from below the coal seam, possibly the Trout Creek Sandstone which has a water temperature of approximately 17 degrees C (refer to 1983 data). The conductivity an•d pH of the fault water is higher than that of the Trout Creek Sandstone. This can be
