HARD DATA (CONTINUED)


GETTING A LOAD OF DATA


This is particularly important when the new crusher with its greater capacity comes into play. So currently we are looking at overall loading tool performance, analysing reports on three key outcomes for the Cat 992K units. These are the load time for every load, the average load time and the number of passes each loader puts onto the truck. 


 “Because we have on-board weighing and visible monitors on the outside of the Cat 777G trucks, the operators know when a load is complete. Equally we know that from the 10.7 cubic metre capacity of the bucket and material density, it should take on average five buckets to fill a Cat 777G skip. 


“So if we see an average of six bucket loads for each truck, we know we have an inefficiency in the process of up to 20 per cent, which increases fuel burn, ground engaging tool and component wear, cycle times for the trucks and ultimately adds cost to the extraction process. Often this type of scenario can be down to things like the blast and the fragmentation of the material from one bench to another. However knowing this information allows us to change operations, in some cases adding or removing trucks from the cycle to reduce idle times.
