'' <br />The waterline will be re-routed through the South Subtnain in D Seam if deemed necessary. To this <br />date, no damage to the waterline has been observed. <br />' The transmission line will be monitored for any tilt of the poles. The poles will be properly guyed in <br />place. A plan for the same was designed in advance of mining underneath the transmission line poles. <br />' To this date, no damage to the transmission line has been observed. <br />' 4.2.5 Miningiggnence Mining sequence is shown in Plates 7 and 8. During 1991 about 800 feet <br />of East Mains will be developed. Approximately 3850 feet of the tailgate for longwall panel 6 (LW-6) <br />will be developed. LW-4 will be mined out in 1991. Approximately 3900 feet of LW-4 and 1500 feet <br />of LW-5 will be mined in 1991. In 1992 the LW-6 tailgate will be completed and about 5700 feet of <br />the LW-6 headgate will be developed. Approximately 4400 feet of LW-5 will be extracted. In 1993 <br />the headgate for LW-6 will be finished. The East Mains will be extended about 1000 feet. The <br />headgate for LW-7 will be started. LW-5 will be mined out and approximately 2400 feet of LW-6 <br />will be mined. In 1994 the headgate for LW-7 will be completed and approximately 2200 feet of LW- <br />' 8 headgate will be developed. LW-6 will be mined out and approximately 700 feet of LW-7 will be <br />extracted. In 1995 the East Mains will be extended and the headgate for LW-8 will be developed. <br />' About 4400 feet of LW-7 will be mined. <br />The following events take place during 1996-2000. Development of LW-9 through LW-14 will be <br />' completed. Longwell panels 8, 9, 10, and 11 will be fully extracted, and LW12 will be partially mined. <br />' The following events take place during 2001-2005. In the D seam, LW-15 through LW-20 will be <br />developed, completing all development work in the D seam. L.ongwall panels 12, 13, 14, 15, 16, and <br />part of 17 aze mined out. RP-1 and RP-2 aze fully mined. Development of the B seam access mains <br />begins in 2005. <br />The following events take place during 2006-2010. In the D seam, the remaining longwall panels 17, <br />18, 19, and 20 aze mined out and all mining in the D seam is completed. In the B seam, development <br />of the South Mains Left is complete. Part of the West Mains is complete and the first three longwall <br />' panels aze developed. Mining of LW-1B begins in 2010. <br />' The following events take place during ZOll-2015. The B seam longwall panels 1 and 2 aze mined <br />out and LW-3B is partially extracted. Development of the West Mains continues. Development of <br />LW-4B is completed and LW-SB is started. Room-and-pillaz azeas 1, 2, 3, and 5 aze mined out. <br /> <br /> 25 <br />1 <br /> <br />
