Water was encountered in Well B-6 for the first time during the October 1987 sampling. The water level was recorded at an elevation of 5958.2. This level is approximately 60 feet below that recorded in Well H-10. Over time, it is anticipated that the water levels in both wells will equalize as the mine workings fill with water. Water quality collected in October is very similar with that of well H-l0 described above. Comparison of the 2 wells is presented in Table 1 and Appendix 1. The water has a slightly higher degree of mineralization. INFLOW TO MINE WORKINGS As part of the water management plan, Kaiser has monitored water levels in Wells H-10 and B-6 to assess the rate of mine flooding. From October 1986 to May 1987 water level in H-10 rose approximately eight feet. Water was also encountered in well B-6 for the first time in October 1987. However, as indicated on Map 2 and accompanying cross sections, water elevations in the two wells are not the same. The primary reason appears to be the hydraulic connection of the underground workings in some areas and unmined blocks of coal which separate the various mined areas. These unmined blocks act as barriers which allow lower areas of the mine to fill first and at different rates. Map 2 presents the water elevations as projected during April and October 1986 and October 1987. As displayed on the cross section maps, the mine workings follow the coal structure dipping to the north and east. The stabilization of water level measurements during 1987 over those recorded in 1986 may be due to the lower portion of the mine (in the area of Well H-10) being filled to a point where excess water would enter that portion of the mine where Well B-6 is located. This may also explain the immediate presence of water observed in Well B-6 from the third to the fourth quarter of 1987. Additional studies during 1988 will further confirm these projections. i
