Backfilling <br />• accomplished <br />construction <br />road. <br />of the mine access road and mine bench will be <br />by excavating material that was overcast during <br />and placing that material on the bench and access <br />The backfilling plan is shown on the Existing and Final Contours <br />and Sections Map, (Map 12). Because the access road and bench are <br />prelaw disturbances, no topsoil was salvaged so none is available <br />to be placed on the backfilled access road and bench slopes. The <br />sections shown on Map 12 indicate that approximately 7,932 cubic <br />yards of overcast material will be excavated and placed on the <br />bench and access road. Approximately 9,846 cubic yards of fill is <br />required. The excavated material will swell 158 to 208 therefore, <br />a reasonable material balance exists between cut and fill (7,932 X <br />1.2 = 9,518). <br />Reclamation work on the previously constructed face-up will be <br />implemented as part of the initial construction whenever possible. <br />For example, the slopes at the top of the portal face cut will be <br />rounded if possible. The benches and the portal face-up above the <br />• mine entries will be stabilized with netting and revegetated <br />shortly after initial construction. All slopes will be broadcast <br />seeded with cyclone seeders using a rate double that found in Table <br />10, Proposed Seed Mixture. A netting will be spread over the <br />slopes to anchor mulch and soil stabilization practice. Drainage <br />off the portal face cut will be treated similar to a contour furrow <br />with periodic baffles and with the bench sloping into the hill. <br />This configuration will prevent drainage from flowing over the top <br />of the bench. <br />• 2.05-35 Rev. 04-30-93 <br />i~ <br />
