A hydraulic shovel will be used to excavate sandy clay and load into a 12 BCY dump trucks. The shovel's production at a 100% efficiency is estimated to be 300 BCY/h. and efficiency is 0.80. Truck travel time is estimated to be 8.0 minutes, and truck fixed cycle time (excluding loading ) is estimated to be 2 minutes. Equipment cost for the shovel and trucks are $40/hr and $20/hr respectively.
Calculate the expected production and unit cost of loading and hauling if the truck fleet consists of five trucks.
