mar;mum. The Wadge Seam will be mined out and production will be gradually phased down during the last few <br />years. The estimated mine life, based on maximum annual peak production of 10,000,000 tons, is 11 years. The actual <br />• mine life is subject to extension in case of the sales market remaining soft, resuhing in a lower yearly production. <br />Productivity estimates were based on expected mining conditions and analysis of productivities at other westem <br />U.S. mines. It is expected that gradient and water inflows will significantly reduce down dip development <br />productivities. It is assumed that six continuous miners and two longwalls will be required to reach maximum <br />yearly production. The continuous miner productivities would vary from 200,000 to 325,000 tons per year per unit <br />depending on location. Longwall productivity is expected to be approximately 6,000,000-9,000,000 tons per year <br />per unit. <br />Labor Force <br />The Foidel Creek Mine Labor force schedule is shown in Table 47, Labor Force Schedule, Table 48, Hourly Labor <br />- Maximum Production, and Table 49, Salaried Labor -Maximum Production. The total number increases from an <br />estimated 47 in 1983, for a one section mine, to 497 in 1992, at full production. The current work force is <br />approximately 370 people (1998). ~ ~ 30o C~ooo~ <br />Mining Eauioment <br />The Foidel Creek Mine will use standard mining methods and equipment commonly used in the westem U.S. coal <br />industry. <br />A longwall section will contain the following representative list of equipment: <br />• 170 Shield Roof Supports <br />Armored Face Conveyor <br />Shearer <br />Stage Loader <br />Electrics <br />Hydraulic System <br />Miscellaneous Pumps and Tools <br />A typical continuous miner section will contain the following equipment: <br />Continuous Miner <br />Haulage Cars <br />Roof Bolter <br />Feeder Breaker <br />Electrics <br />Mantrip Vehicle <br />LHD Scoop <br />Parts Car <br />Continuous Haulage System <br />Rock Duster <br />Miscellaneous Pumps and Tools <br />The following types of utility and support equipment will be utilized in the Foidel Creek Mine: <br />Electrical Distribution System <br />Conveyor Systems <br />APPROVED JUN 2 8 2000 <br />PR 99-OS 2.05-10 8/27/99 <br />
