<br />REFERRAL CALCULATIONS <br />II-1 Dozer Calculation <br />1987 D9L <br />To: Push area 200' x 600' x 20' into pit for Smooth Grade slope to Contour <br />Average Push distance - 100' <br />1200 LCY /Hour Production <br />Use: 50,000 LCY (Gravel) for sloping <br />So: 50,000 LCY _ 1200 LCY/Hour = 41.667 Hour <br />Use 50 Hours at $141/Hour <br />COST: $7.050 <br />II-2 Shoot Highwall Calculation <br />To: Drill and shoot the highwall on the east side of the pit to rough grade into pit at 3:1 <br />highwall . Use 250 feet wide by 1000 feet long by 30 feet high. 138,889 BCY or <br />187,500 LCY <br />Contract Drill and shoot at $.20/BCY <br />COST: 138,889 at $.20/BCY = 27 778 <br />II-3 Rough Grade East Highwall Calculation <br />]987 D9L <br />To: Use 1987 D9L Dozer to push shot highwall to 3:1 slope in pit. Have 40% of Highwall <br />material shot to pit with blasting. Therefore 40% of ] 87,500 LCY is shot to pit leaving <br />l 12,500 to be moved with dozers <br />Push distance of 100 feet. <br />1200 LCY/Hour production <br />So: 112,500 LCY - 1200 LCY/Hour = 93.75 Hour <br />Use 100 Hours at $141/Hour <br />COST: 100 hours at $141/Hour = 14 100 <br /> <br />JAN ~ 5 1393 <br />
