4.14 BACKFILLING AND GRADING <br />• <br />4.14.1 General Requirements <br />The mining operations of the Bear Coal Company will not employ the use <br />of contour mining, open pit mining, ur area strip mining techniques. <br />Rather, the mining techniques to be used by the Bear Coal Company will <br />be underground mining utilizing a room and pillar technique. <br />At the completion of mining activities, the surface areas disturbed <br />incidental to the underground mining will be backfilled and graded. The <br />disturbed areas will be returned to the approximate original contour by <br />grading and backfilling with the use of bulldozers. Additional detail <br />of the backfilling and grading for the surface facilities and portal <br />areas of the Bear operation is set forth in the discussion under <br />Sections 2.05.3 and 2.05.4. <br />• 4.14.2 General Grading Requirements <br />The final graded slopes of the surface facilities and portal entry <br />locations will be restored to the approximate original pre-mining slope <br />grades as shown on the Post-Mining Topography Map (Map 12). The Bear <br />Coal Company will retain all overburden material on solid portions of <br />existing or new benches. The face up area for the portal entries will <br />be eliminated by partial backfilling overburden and prompt revegetation <br />to control erosion. <br />Final grading before topsoil placement will be done along the contour, <br />unless a specific area would cause a safety hazard to the operator, in <br />which case grading would be other than along contour. Specific <br />discussion of the plan for and sequence of backfilling and grading is <br />set forth in the discussion under Section 2.05.4. Topsoil placement <br />will be stabilized in these areas with the use of farming equipment by <br />disking, chisel plowing, andJor furrowing. <br />• <br />4.14-1 <br />
