When mines are looking to increase haulage capacity, they typically consider adding more trucks to their fleet. But that may not necessarily be the most cost-effective solution.
Loadscan, the leader in Load Volume Scanning, has experienced numerous situations where mines have initially planned to buy extra haulage capacity in the form of new trucks. Additional trucks certainly add capacity, but not only are trucks expensive and consume a huge amount of valuable capital but running them requires additional driver resources as well as consumables such as diesel and tyres. In addition, every truck requires ongoing maintenance and servicing. This can add substantially to extraction and haulage costs.
The other issue is that an additional truck may provide more capacity than the mill can process, ending up being underutilized. In this situation the full capex cost has to be amortized against the apportioned usage and not against the truck’s full production capability, negatively impacting on the mine’s return on assets.
There is a way to substantially increase capacity without the need to acquire additional trucks and their associated costs. Based on experience, Loadscan has seen underloading of trucks in the mining industry ranging from 7.5% up to a whopping 25%! Underloading requires additional truck movements to shift the same amount of material, increasing the cost per ton hauled and reducing overall proﬁtability.
Automated Load Volume Scanning helps mines to optimize capacity by maximizing every load, thereby increasing trucking factors and improving proﬁts. The Loadscan Load Volume Scanner (LVS) accurately measures all loads and generates 3D scan images that clearly indicate underloading, enabling corrective action (including operator training and coaching) to be taken.
Hindustan Zinc, the world’s second largest zinc producer, has deployed four Load Volume Scanners across two of their mines. Pavan Kaushik, Vice President and Head of Corporate Communication at Hindustan Zinc said, “Loadscan has been helpful to improve operational performance by managing carryback and reveal our true shift tally. We can now accurately calculate net volumes delivered for processing. Time is also saved by minimizing paperwork – there is no manual data entry, driver records or after-shift record sorting.” All mining trucks in Hindustan’s fleet are fitted with RFID tags, allowing the tag reader in the LVS units to automatically identify each truck as it passes under the scanner, avoiding bottlenecks.
Loadscan has worked with numerous mines across the globe to cost-effectively increase haulage capacity. Every small piece of payload information miners can get from the Load Volume Scanners leads to increased trucking factors, which in turn lowers the cost-per-tonne hauled. Typical increases achieved have been anywhere from 7.5% up to 25%, adding millions of dollars to their bottom lines!
Loadscan LVS scanner systems are available in portable, semi-portable and fixed gantry models. The system can be configured to suit all site applications, be it a large-scale surface operation running large rigid dumpers, an underground mining operation or a remote mining operation utilizing standard on-road trucks.
