• within the delineated lifts of the pit area will be mined alternately in this sequence. <br />Please observe the photos of the model in Appendix 5-3. <br />Prior to any of the mining events, woody plant species, (e. g., pinyon pine juniper, <br />serviceberry, chokecherry, or other large shrubs or trees), will be bladed into a brush <br />pile, in advance of soil salvage and stockpiling. Next, all available topsoil will be <br />removed and stored for redistribution as per Section 2.05.3(5). <br />Mining will begin in the dip-slope area of the North Pit and proceed to the outcrop of <br />the Lewis ("C") seam in segment A-1 in the west portion of Section No. 1 as shown on <br />Map 5-2. There is very little soil in this vicinity, but all that is available will be <br />removed and stockpiled in the topsoil stockpile. (See Map 5-l and J-2 for soil location <br />stockpiles). The overburden has been placed adjacent to segment A-1 on the west side <br />in the drainage. The mine plan map shows this area. The creation of work benches in <br />each segment will facilitate the construction of haul roads and ramps into the active <br />pit(s) above the coal seams on which the mining equipment will work. The surface <br />area for these segments is described below. The present status of mining as of this <br />submittal has been shown on Map 5-7. <br />Coal Remove/ <br />• This section should be read and understood in conjunction with the discussion of <br />overburden movement. The wmbined area totals 14.4 acres and will require a span of <br />approximately fourteen months to mine. The time requirements to mine each segment <br />is: A-1: 2.2 months; C-1; 4.2 months, and portions of I-1 and I-2: 4.2 months. <br />An additional time span of about two to four months may be needed at this stage for <br />extraction of coal from segments D-1 and E-1 before segment C-1 is completely <br />backfilled, using spoil from segments E-1 and F-1. Phase I will carry over into <br />segment C-1 and D-1 until sufficient overburden and coal has been removed to <br />facilitate future haul road construction into segment D-1 and E-1, and segment C-1 can <br />be completely backfilled and regraded, as mentioned above. Thereafter, Phase [I will <br />begin. Phase II will continue to be bench mining in segments E-1 and F-1, with <br />concurrent backfilling behind the active pit. <br />Segment A-1 covers 0.8 acres, and C-1: 4.5 acres. Segment D-1 covers approximately <br />2.8 acres, and Segment E-1 covers 3.5 acres. The North Pit (coal Segments I-1 and I- <br />2) will be mined first and the reclamation will be complete when active mining begins <br />in the South Pit. Additional portions of Coal segment F-1 will be mined concurrently <br />with Segments C-1, D-1 and E-1 if the quantity of rock in those segments is not <br />adequate to complete the steady state pit. The balancing of the benches and pit size for <br />the desired tonnage dictates that the multiple segment be handled simultaneously. This <br />will conclude Phase I. <br />u <br />Technical Revision 08 (v 1.3) Sfi Revised 9/1997 <br />
