Using the data of Problem 7, calculate the expected production and unit cost of loading and hauling if the truck fleet consists of five trucks.
Â
Problem 7
A hydraulic shovel will be used to excavate sandy clay and load it into 12-BCY (9.2-BCM) dump trucks. The shovel's production at 100% efficiency is estimated to be 300 BCY/h (229 BCM/h), and job efficiency is 0.80. Truck travel time is estimated
a. How many trucks are theoretically required to obtain maximum production?
b. What is the expected production of the system in bank measure using this number of trucks?
c. What is the expected unit loading and hauling cost ($IBCY or $IBCM)?
