2ule 2: Permits <br />Typical support equipment for the surface mines include the following (or equivalent): <br />• Dozers <br />Drill Rigs <br />Front End Loaders Backhoes <br />Haul Trucks <br />Road Graders <br />Mechanized Broom Maintenance Trucks Watering Truck <br />Portable storage facilities are supplied for bulk quantities of explosive materials and diesel fuel. <br />Surface Mining Sequence <br />Mining operations at the Jeff Canyon Mine began with the establishment of the haul road <br />up Jeff Canyon to access the mining areas. Existing access roads were upgraded wherever practicable to <br />minimise surface disturbance. The yearly-designated mining blocks are projected areas for mining by the <br />azea method on the N and higher seams. A railroad load-out facility will be established for the purpose of <br />shipping coal produced from this mine to the Picketwire Processing Plant for processing and unit train <br />loading. For times when railroad loading at the mine site is not feasible, coal will be trucked to the <br />Picketwire Processing Plant on State Highway 12. <br />Prior to mining in any given area, ponds and drainage structures are built per approved plans. Fill areas <br />upstream of the ponds are cleared and made ready for placement of excess spoil from the initial mining <br />cuts. <br />. The northeast end of the ridge between Cow Canyon and Jeff Canyon was mined first. The material from <br />this fast mining was placed in the fills on the southeast and northwest sides of the ridge. A contour cut <br />was made along the outcrop of the lowest seam to be mined (Ol). The material from this cut was pushed <br />with dozers or end dumped into adjacent or nearby fills. The highwall of the contour cut reaches the <br />outcrop of the next highest coal seam (0). Figures 2.05.3-1 through 2.05.3-4 reflect the mining sequence. <br />2.05-5 (revised 06/15/03) <br />• <br />
