PERTH (miningweekly.com) – Diversified major Rio Tinto this week revealed that it would deploy the world’s first fully autonomous water trucks at its $2.6-billion Gudai-Darri iron-ore mine in the Pilbara region.

The new vehicles, primarily used for dust suppression on site, will enhance productivity by enabling mine operations to digitally track water consumption and reduce waste.

Developed through a successful collaboration with leading equipment manufacturer, Caterpillar, three water trucks will join Gudai-Darri’s fleet of Caterpillar heavy mobile equipment including autonomous haul trucks and production drills. The vehicle’s intelligent on-board system detects dry and dusty conditions on site, triggering the application of water to roads to keep them in good condition.

The refilling process is also completely automated with the water trucks recognising when it is time to refill, prompting them to self-drive to the water stand, park and top-up before returning to the field. They boast a 160 000-litre tank capacity, a 33% increase on Rio’s largest water truck which has a tank capacity of 120 000-litres.

Once deployed, the water trucks will be integrated into Rio’s existing Autonomous Haulage System which has been shown to significantly improve safety by reducing the risks associated with operators working around heavy machinery.

“We have worked closely with Caterpillar to safely and successfully deploy the world’s first fully autonomous water truck. Water spraying is a vital part of mining operations and this new technology will improve productivity and reduce water usage across our operations” Rio iron-ore CEO Simon Trott said.

“The continued expansion of our autonomous fleet helps improve safety and continues Rio’s efforts to adopt world-leading technology to enhance our operations and realise our vision of making Gudai-Darri one of the world’s most technologically advanced mines.”

Construction at Gudai-Darri continues to progress with production ramp-up on track for early 2022. Once complete, the mine will have an annual capacity of 43-million tonnes, underpinning production of the Pilbara Blend, Rio’s flagship iron-ore product.
