Reclamation will lag production by 2 production <br /> Blocks. This will allow a safe working space between production and reclamation activities. <br /> Mining <br /> • Loading & Screening. An excavator will feed material into the power-screen hopper. The <br /> excavator will be equipped with a 1.2 yd3 bucket. A small bucket was selected to allow for <br /> selectivity during mining. The power screen will be set a 2-inch. <br /> +2-inch material is generally development rock.Testing has shown this to be low grade considered <br /> to be waste. Waste will be stockpiled by the power screen waste conveyor, then will be used as <br /> fill for; (1) existing exploration holes, and (2) collapsed shafts, safety permitting. Waste piles are <br /> shown in Figure 6-7, Exhibit E Section 6.4. <br /> The power-screen "ore" conveyor will directly load 12yd3 tandem trucks for transport to the mill. <br /> • Hauling. The trucks will haul the material approximately 5.8 miles to the Leadville Mill for <br /> processing. <br /> • Utility. A small bulldozer and loader/backhoe will be on site for site clean-up, haul road <br /> construction and maintenance, and reclamation grading. A mulcher will be on-site to create the <br /> Mulch. <br /> • Water Truck The water truck will be used for on- and off-site road dust control mitigation <br /> Mine Equipment. The following equipment will be on site. <br /> Table 4-2: Mining Equipment <br /> Units Description Nominal Size <br /> 1 Excavator 1.2yd3, 159hp <br /> 1 Power screen double deck, 20hp <br /> 1 Dozer 10', 135hp <br /> 2 Haul Truck,Tandem 12yd3 <br /> 1 Loader 3yd3, 231hp <br /> 1 Water Truck 4,000 gallon <br /> 1 Mulcher - <br /> 4.1.6 Significant Disturbances <br /> 6.3.3(1)(f).
