RULE 2 - PERMITS <br />relnainino development. The sections x�Ill be a three entry system employing the proven geometry <br />of an abutment /vield pillar design. The rigid pillar will be 100 to 150 feet in width and 200 to 300 In <br />length. The yield pillar x�ill be 55 to 60 feet in \�idth and 100 to 150 feet in lem-th. For the <br />development phase, mining depth will range from 100 feet at the portal to 1.600 feet hear the end Of <br />the sections. It is expected that four continuous llllller sections NN-111 be developed. and the Illalns <br />will be extended to each section. 1 he gencral underground mine workings la} out relative to the <br />surface portal and sequencing is shox\n on Map 2.05.3 -M2, Mine Plan Mali, Operations lin-III10 <br />Portal facilities Construction is projected to occur in the first 1 -'/ years. <br />Using a Continuous 111111111` Method. the COntInLIOUS Miller Cuts coal as It moves into the Scalll. <br />discharging the coal into shuttle cars. As each shuttle car is filled, the coal is transported to the <br />feeder- breaker. Coal is emptied into the feeder - breaker hopper, crushed, and discharged onto the <br />belt tailpiece. The section conveyor transports the coal to the lnallllllle cO11vC}'01 -. which transports <br />the coal to the surface. Any significant quantities of rock material produced dllrlilg Millie <br />development «ill be loaded on the conveyor and transferred to the surface for separate handling as <br />waste rock. Prior to making each cut, a rootbolter installs rootbolts and supplementary roof support <br />according to the approved MSHA roof control plan and mine conditions. .Overall coal recovery for <br />a continuous miner pillar section seldom exceeds 50 percent. due to the necessity of leaving pillars <br />to support the overlying strata. The proposed initial development will be limited to advance mining, <br />with no plan for retreat mining or pillar recovery. <br />The PSCM permit area encompasses an area of approximately 10,164 acres. Of this total, <br />approximately 276 acres will be affected by surface disturbance and facilities construction <br />incidental to PSCM underground mining activities. Given that initial development will be limited to <br />main entry and section development with no subsidence predicted. 11m\ ever, a worst case <br />subsidence scenario ,vas developed and resulted in a 1264 acre potential affected area (see section <br />2.03.8 and Map 2.05.2-MI, Mine Plan Map. and 2.05.6(6), Subsidence Survey, Monitoring. and <br />Control Plan). Mine disturbance areas incidental to underground mining activities will be identified <br />by post or markers, with the upper 1 -1.5 feet of the post painted red, fir visibility, which will be <br />maintained until bond release per Rule 4.02.3. Annual production x\ill be dictated by market <br />demand and is subject to yearly adjustments. During the initial permit tern, all coal mined will <br />come from reserves that are either owned or leased by PSCM. Table 2.05.3 -T1, Production <br />Schedule Years 1 -5 shows anticipated production. <br />Labor Force - The anticipated PSCM labor force schedule is presented as Table 2.05.3 -T2, Labor <br />Force Schedule. Total employee members increase from an estimated six in Year 1, for initial <br />construction to approximately 195 in Year 5. <br />Table 2.05.3 -T1: Production Schedule <br />(000's tons) <br />Year 1* 2* 3 3/4 4/5 <br />Tons Produced 0 500 1,500 2,000 2,000 <br />* Years 1 & 2 are facilities construction.
