A shovel with a 4-cy heaped capacity bucket is loading poorly blasted rock. The average height of face is 16. 5 ft and the maximum digging height of the machine is 33 ft. The haul unit can be positioned only at 180 degrees swing angle. Assume optimum height for the machine as 50% and rock material swells 60%. If the efficiency is 50 min per hour, calculate: 1. The shovel production in bcy per hour ---- 2. The operation cost per bcy if cost of shovel including wages is $116.00 per hour -----
