The 650 dragline is cimently excavating on the north pardon of this area, developing pits into a shallow J-shape in a northeasterly-westerly orientation. As the pit is further developed daring the 1992-1996 pP*~; t term, the pit orientation will gradually shift northeasterly-southwesterly and continue to generally progress southeasterly until anticipated cmnpletion of the pit in 1997. Some operational problems are anticipated along the northwest cropline in Section 2 where overburden depths approach 140 feet. If the excavation equipment is unable to effectively uncover the coal reso~sce, the pits may be chnrtnnc+r3 tp better aoooimnodate equipment capabilities or auxiliary equipment may prestrip a portion of the overburden. Scare minor quality and • coal removal scheduling difficulties may also be experienced due to a shale parting ooasring in a portion of the coal field. Should the opal be of inadequate quality, alternate haulage raags may be necessary on a tei[q~arary basis. The Wadge pit, south and east of the Wolf CreP]c pit, is identified on the Operations Plan map as the West arri East Wadge pit. Currently, these pits are generally located in the SF?; Section 11 and the N; Section 12, T5N, RB7W, respectively. The 77oB dragline has stripped in both pits. licxaever, west pit excavation has been oongrleted and final coal removal is oongrleted. Active minim is ongoirg in the east pit by the 650B dragline. This pit has developed into a nort2nrest-southeast arientation and will progress in a northeastpsly direction until the mining is completed in 1997. The 770 dragline is c~m~errtly operating at the Seneca II-W . Mine. The 650 dragline, at the Seneca II Mine, rrarst now work both the Wolf Creek opal seam arxi the Wadge coal seam simultaneously.
