is the project ed final highwall IocaU On, and augeri ng areas will vary Lased on the enact <br />fr nal highwall locations and assocrated mining conditions. <br />3. Augeri ng operations will b= conducted dun nq da yl iyhr hours on a 5-C+ day/week schedule based <br />nn [he current anticipated mine production projections. If conditions, machine availability, <br />or coal demand requrres that the auger work. after dark, adeq uare rllumr nation for the work <br />areas shall be pcovrded. <br />4. Coal will be ea[racted utili unq the auger, starting within the coal seam [o ma:u nii ze <br />recovery and coal quality, wt[h a b-loot diameter cutting head and a pcten tr al penetration <br />depth of up to 600 feet. Only a single pass will be made. <br />5. Coal will etcher be conveyed cote [he pit floor or di rec[ly into the haulage trucks. If <br />cam veyed onto [he pct floor [he front-end loader will stack the c~ai away from the auger for <br />loading of a later rime. <br /> 5. Coal haulage ttaffir will be routed through the pit area using the established pct ramps <br />• traveling in a ono-way dir?ctronal flew F.a [tern only. <br />~. In the event of a blast eccurn ng within 1000 feet of the auyer operations, the auger will <br />cease operatton and bacY. away from the t~iyhwall a mtnt mum of 50 feet. Upon completion of the <br />blase and the all-clear signal given, the highwall shall he reexamined for any problems <br />r_a us ed by the blast, and rommence auge ci ny r[ [he hrghwall has peen deemed safe to proceed <br />agar n. <br />8.
