rC /hr. divided by _� shifts/day = $ /y,,, pc average loader cost/hr.
MATERIAL QUANTITIES:
Bank volume = BCY x swell factor = 6 y�o o LCY
Verification methods used �,�„ w►� _ �_,�.
HOURLY PRODUCTION:
Haul distance = o0 o ft. , return distance = Q !2 ft. , altitude = boa ft.
Total resistance au a % rolling res -�% grade res. +or- = o %
Total resistance (return) : % rolling res. plus % grade res. (+or-)= f %
Note: for grade resistance, (+) = unfavorable, favorable (downhill )
Truck capacity = 12 LCY (nominal heaped)
Loader capacity = -7 LCY (nominal heaped) x bucket fill factor from
fill factor a jua' stment table in Section VII = ! LCY/bucket load (adj. cap'y)
No. of loader passes required to fill truck = ,3 (round to nearest whole no. )
Adjust truck capacity = /�2_ LCY
