(Ripping Road)
EQUIPMENT: D-8K Dozer with ripper
ASSUMPTIONS:
Efficiency = 80°.6
Altitude Adjustment = 93%
RR = N/A
Seismic Velocity = 4,000 fps (estimated)
Conditions =Medium
Reclamation of the haul road will require ripping the top 3 feet of mate-
rial prior to removing any surfacing material.
Maximum length of haul road = 2,640 feet
• Average haul road width = 30 feet
PRODUCTION = 1,250 cubic yards/hour (ripping -Cat Handbook, p. 60)
ACTUAL PRODUCTION = Ideal x Alt. Adj. x Eff.
= 1250x.93x.80
= 930 cubic yards/hour
VOLUME 2640'L x 30'W x 3'D
27 cu. ft. cu. yd.
= 8,800 cu. yds.
TIME = 8,800 r 930
= 9.5 shifts
• COST= 9.5 shifts x $994.28/shift
_ $9,445.66
