SPL: AGGREGATE HAULING/TIMESPOTTING

A. QUARRYING

Output of one (1) D4 Bulldozer 210 cu.m./day of unprocessed matl.

B. SCREENING AND STOCKPILING

GENERAL FORMULAFor Wheel Loader:

Q = q x (60/CM) x E

Where:Q Hourly production in cu.m./Hourq Production per cycle

CM cycle time in minutesE Job efficiency

q = q1 x k

Where: q1 Heaped capacity of loader

k Bucket factor

CYCLE TIME (Cm) FOR LOADER1. In a cross loading

Cm = D/F + D/R + Z

2. For V Shaped loading

Cm = D/F + 2 + D/R + 2 + Z3. In Load and carry

Cm = D/F x Z

Where: Cm cycle time in minutes

D Hauling DistanceF Forward speed in meters/minute

R Reverse speed in meters/minutZ Fixed Time (minutes) sum of gear shifting, loading, turning,

dumping and waiting time

Computation of screening and stockpiling output for wheel loaders (articulated), use job

efficiency (E) of 0.83 (83%) Cm = 1.00 Minute (Cycle time for screening 1 bucket ofunprocessed material)

GENERAL FORMULA:

Q = q x ( 60 / Cm) x E; use q = use struck bucket capacity= q x (60/1) x (0.83)

= 49.8 cm./hrwhere: q is the struck bucket capacity. However, for screening fine and course

aggregates, introduce (f) quarry factors to the general formula, therefore,1. For screening fine aggregates

Q = 49.8 qFf (cu.m./hour)

2. For screening course aggregatesQ = 49.8 qFc (cu.m./hr)

Where: Ff = quarry factor for fine aggregates

Fc = quarry factor for course aggregates

Moreover, in the screening process of fine and course aggregates, there is extra timerequired for stockpiling screened waste. Materials which needs to be determined as factor of

cycle time to be multiplied to the above formulas to arrive at the output.
