Currently, all box cut spoil fr~n both the Wadge E~St and West <br />pits has been completely graded aryl reclaimed. <br />Backfillina Final Pit. As described earlier in this docurmnt, <br />minirx3 operations are wnducted from recovery line to <br />cropline. Ammxl other reasons, this method reduces the ammmt <br />of final pit highwall reduction that must be performed. <br />Because of the anticipated recovery depths, theoretically, <br />little highwall should be available after backfilling. <br />However, a final pit highwall may need to be reclaimed along <br />both the Wadge aryl Wolf GYeek recovery lines. In on9er to <br />reclaim the final pit to approximate original cnntois, a <br />number of mining operations must be conducted as generally <br />shown on Figure 12-9 and described below. <br /> <br />~~ <br />12-54a Revised 10/01/86 <br />
