Revised 12/21/82 <br />strutting ground. Native grasses will also be included for <br />livestock, deer, and antelope, which frequent the area. <br />Backfillinq and Grading <br />The proposed post-mine contours for the Bourg property are <br />illustrated on Plate 20. This final surface will be established <br />after Sfoge I and during Stages 4-10. Backfilling will include <br />returning overburden to the pit, in order to construct a minor <br />drainage, and reconstruction of a small ridge. <br />All spoil shall be Transported, backfilled, and compacted in <br />a manner which will ensure stability, minimize off-site effects, <br />and support the post-mining land use. Scrapers and bulldozers <br />will be used to conduct earthmoving activities and final grading <br />will be done by a motor grader. <br />As seen on Plate 20, Walden Coal Company will be relocating <br />• a ridge approximately 200 yards northeast of its original <br />position. The relocated ridge is called the "East Dump" in the <br />mining plan. Although the backfilling plan necessitates this <br />minor displacement of a ridge, the final graded slopes will <br />aproximate the general nature of the pre-mining topography. <br />A swell factor of 23 percent was assumed (using information <br />obtained from nearby mines which are mining the same formations), <br />in developing the proposed contours (Table 4(0)). By following <br />this backfilling plan, approximate original contour will be <br />achieved and all highwalls, depressions, and spoil piles will be <br />eliminated. <br />` _ 9- <br />F-~ <br />
