1 <br />The two remaining upper facies holes with water (29-4U and 33-SU) experienced drops in <br />' water level. 33-SU showed a noteworthy drop of 9.0 feet. This drop is potentially due in <br />part to the close proximity of longwall mining but more significantly the continuing effect of <br />' a prolonged dry cycle. Longwall panel LWB-6 was mined out in early April 2005 and was <br />located as close as 1400' from this hole. <br />' Water levels in monitoring hole 29-4U decreased 5.1 feet from the prior year. We may be <br />starting to see a slight influence from the mine workings. However, most of the effects are <br />probably due to the continuation of drier than normal conditions. Longwall panel LWB-7 <br />' was within 3200 feet of this hole and the development section for the next panel mined <br />within 2100 feet. <br />' Monitoring hole 22-3U was completed in November 2005 for monitoring future mining <br />expansion. While not yet required by the existing permit, data for this well is shown in <br />Appendix C. <br />The middle "siltstone-coal facies" monitoring holes are designated by an "M" following the <br />hole number. These monitor holes are open through the interval containing the D Seam <br />and B Seam. <br />' Monitor hole TW2-17M was surrounded by mining first in November 1985 but was not <br />intercepted in the workings. It is apparently located in a pillar completely surrounded by <br />' open workings. At that time it showed virtually no response to room-and-pillar mining. In <br />February 1988 longwall panel 1 was mined to within about 900 feet of this hole. <br />Obviously, longwall mining disrupts the mined zone more than room-and-pillar mining, <br />' and the water level in TW2-17M did show a response to mining at that time. The water <br />level has steadily decreased since 1988 with a decrease of 7.7 feet since the last <br />monitoring period. <br />' Water levels in monitoring hole 29-4M decreased 5.5 feet from the prior year, similar to <br />' that of 29-4U. Most, if not all, of the effects are probably due to the continuation of drier <br />than normal conditions. <br />' The water level in Hole 30-8M decreased 19.3 feet. The cause of this decrease is most <br />likely the advancement of mining development nearer to the well. This well is scheduled <br />' to be mined through in December 2006. Qualitative sampling of this well will take place <br />prior to being mined through. <br />' Hole 31-7M decreased in water level 2.2 feet. This well is up gradient from mining <br />activity and the water level fluctuation can be attributed to the prolonged dry period. <br />5 <br />
