Power for the Miner The miner can be powered from a utility grid or if being operated in remote areas, using a Cat generator set available from any Cat dealer. The machine is provided with our 2250 kVA “Global Transformer,” which accepts the following standard power supply voltages (+ and – 5%):

60 Hz: 7.2 or 4.16 kV 50 Hz: 6.6 or 3.3 kV

Water Consumption Water consumption for surface dust suppression during the mining operation is an average of 1000 L (264 gal) per hour (estimate).
