• production blasting, loaded into haul trucks with hydraulic shovels or front end <br />loaders, and hauled to the appropriate location. The mine areas will be developed <br />in a series of benches. The height and the width of the benches will vary <br />depending on the local geology, stability of the wall material, and mining needs. <br />Discussion of wall heights, bench widths, and stability is contained in Section <br />5.4.5 of this Project Description. <br />The MLE is planned to be mined using existing equipment with replacement as <br />needed and the addition of up to five new haul trucks. Table 5-5 presents the <br />anticipated equipment list. <br />• <br />Table 5-5 <br />Antici ated Equipment List <br />Equipment Specifications <br />Drills Rotary/percussion with 6.75 inch hole diameter <br />Rubber Tire/ Track Loaders 12 to 25 yds bucket capacity <br />Hydraulic Shovels 18 to 40 yds capacity <br />Haul Trucks 85-ton, 95-ton, 150-ton, 240-ton, and 300-ton capacity <br />Dozers Caterpillar or equivalent dozers of D9, D10, and DI I class <br />Trackhoes Caterpillar or equivalent 235 or larger class <br />Water Trucks 13,000 and 18,000 capacity <br />Graders Caterpillar or equivalent 16G or larger class <br />Vehicle Maintenance Includes tire trucks, lube trucks, and service trucks <br />Miscellaneous Vehicles Crew vans and bus and various pick-ups <br />Miscellaneous subcontractor-owned earth moving equipment and maintenance <br />equipment may be on site at various times and in varying numbers during the <br />project. For the MLE, contractor activity would be utilized for utility support, <br />construction of the Phase 5 VLF, growth medium salvage, growth medium <br />replacement during reclamation and equipment maintenance as needed. <br />5.4.4 Drilling and Blasting <br />Overburden and ore will be drilled using track mounted drills. Individual drill <br />pattern spacing and depths may vary. The spacing will be determined by rock <br />characteristics as mining progresses and will change accordingly. Holes usually <br />are over drilled by approximately five feet to accommodate typical bench heights. <br />If bench heights vary, the depth of the drill holes will also vary. Drill holes for <br />• blasting are sampled and assayed to confirm ore from overburden material. <br />Cripple Creek & Victor Gold Mining Company <br />Cresson Project Mine Life Extension <br />5-9
