The projected advances for the truck/shovel and dragline cuts are shown on <br />revised A1ap 23. A range diagram of the generalized dragline operation is <br />shown on t4ap 24A. <br />Coal Removal <br />There will be no changes to the current practice of coal fragmentation and <br />coal loading operations employed in the existing open pit mine. <br />Backfilling and Grading <br />The Section 11 X-Seam pit will be mined predominately by dragline methods. <br />Approximately 2,5 mm BCY of overburden will be mined by truck/shovel methods <br />and approximately 19.3 mm BCY of overburden will be mined by dragline <br />methods. Blast casting will be incorporated into the mine plan. <br />The volumetric balance for the Section 11 X-Seam pit will be accomplished by <br />hauling in backfill material from the existing open pit. Initial cut material <br />mined by truck/shovel in Section 11 will be hauled to dump areas in the <br />existing pit. The initial truck/shovel cut is estimated at approximately 1,3 <br />mm BCY, Therefore, to provide an overall spoil balance approximately 1,3 mm <br />BCY of material from the top benches of the existing Colowyo pit will be used <br />as final dump material in the X-Seam pit prior to topsoiling, The X-Seam pit <br />will be reclaimed in equilibrium with the backfilling and grading balancing <br />the pit advance once the initial boxcut development is completed. <br />Post mining contours for the revision area are shown in a revised Map 19 - <br />Post Mining Topography. <br />The operator is in compliance with this section. <br />XV, Explosives - Rule 2.05.3(6) <br />Tne operator is in compliance with the requirements of this section. <br />XVI. Backfilling and Grading - Rules 7_.05.3(6), 2.05.3(9). 2.05.4 (2 )(a ), <br />There have been no significant changes in the backfilling and grading <br />plan since the original permit review. The operator has been <br />performing annual post-mining topography surveys and swell factor <br />monitoring in accordance•witn the approved plan (see 1992 Findings page <br />37 ). M11onitoring data may be found in the annual reports. During <br />permit renewal the operator requested a decrease in the monitoring <br />frequency to every two and a half (2 -1 /2} years. Based on current <br />data, this request was approved. <br />Additional information on the backfilling and grading plan for the <br />Section 11 TR is given in Section XIV -Operations Plan - of this <br />Findings Addendum document. <br />The operator is in compliance with the requirements of this section. <br />-5- <br />
