~ total truck cost/hr. = s 97.
total loader cost/hr. = S ,tea f
/hr. divided by �_ shifts/day = S S o average truck cost/hr.
S � hr. divided by shifts/day - S 1yo dac average loader cost/hr.
MATERIAL QUANTITIES:
Bank volume = BCY x swell factor G C LCY

HOURLY PRODUCTION:
Haul distance = o ft. , return distance = ,Sam ft. , altitude = /v �,� ft.
Total resistance au : 2 % rolling res. % grade res. +or- _ /�
Total resistance (return) :z % rolling res. plus grade res. (+or-)= _ �
Note: for grade resistance, (+) = unfavorable, t-1 = favorable (downhill )
Truck- capacity = 30 8 LCY (nominal heaped)
Loader capacity = LCY (nominal heaped) x � bucket fill factor from
fill factor a justment table in Section VII = _ LCY/bucket load (adj. cap y)
No. of loader passes required to fill truck = y (round to nearest whole no.)
Adjust truck capacity = Jo. LCY
Loader- cycle time: basic cycle ( load, maneuver and dump) = min.
1st pass = 0.1 min (bulk of 1st pass completed during truck exchange time)
