Caterpillar surpasses 5 billion tonnes of material autonomously hauled

Roughly nine months after reaching the 4-billion-tonne (4.4-billion-ton) autonomously hauled milestone, trucks equipped with Cat® MineStar™ Command for hauling have now moved over 5 billion tonnes (5.5 billion tons), the OEM says.

Cat autonomous trucks are on pace to eclipse previous record totals of materials hauled in a calendar year, projected to be more than 1.4 billion tonnes (1.57 billion tons) in 2022.

Currently, more than 550 mining trucks are equipped with Command for hauling, operating across three continents. Over the last nine years, trucks equipped with Command for hauling have journeyed nearly the average distance between the Earth and Mars with zero loss-time injuries, according to the mining OEM.

Denise Johnson, Group President of Caterpillar Resource Industries, said: “In 2013, we placed our first fleets of autonomous trucks in Western Australia at FMG Solomon and BHP Jimblebar. Since that time, trucks using Command for hauling have safely travelled nearly 200 million km, more than twice the experience in autonomous operations of any automobile manufacturer. Caterpillar has grown the number of autonomous trucks in operation by 40% in the past two years.

“We believe that automation is one of many keys to implement technology that unlocks the value miners need when it comes to the energy transition toward more sustainable operations.”

One of the company’s recent contract wins on the automation front relates to BHP’s majority-owned Escondida mine, in Chile.

Marc Cameron, Vice President of Caterpillar Resource Industries, said of this agreement: “The new Cat 798 AC electric drive trucks replacing BHP’s entire haul truck fleet at the Escondida mine will feature technologies that advance the site’s key initiatives, including autonomy and decarbonisation. The agreement allows Escondida…to accelerate the implementation of its autonomy plans by transitioning the fleet with autonomous haulage system (AHS) technology.”

Caterpillar has enabled 13 customers at 23 different locations to succeed with full site autonomous haulage solutions. Starting with iron ore at Solomon (Fortescue Metals Group) and Jimblebar (BHP), its solutions now manage oil sands, copper, gold, coal, lithium and phosphate. Spanning the 190- to 370-t class sizes, the Cat 789D, 793D, 793F, 797F, and electric drive 794 AC and 798 AC mining trucks are capable of fully autonomous operation. Retrofit kits allow miners to expand Command for hauling to existing Cat mining trucks.

Since 2019, Caterpillar says it has won eight of nine greenfield autonomy sites on offer.

Sean McGinnis, Vice President and General Manager for Cat Mining, said: “In 2023, we will expand Command for hauling to the 139-t truck class at ioneer Ltd’s Rhyolite Ridge lithium-boron mine. This is the first greenfield project in North America to use an AHS. We are now seeing a shift toward autonomy requested on new Cat trucks. Whereas large mines with fleet sizes of more than 70 trucks were the early adopters of the technology, we are seeing economic viability for autonomy at smaller mines with a fleet of less than 15 trucks.”

Caterpillar says it continuously monitors the industry for opportunities to broaden the use of automation to help drive safety and efficiency.

Beyond expansion of Command for hauling to the Cat 785 for ioneer, Caterpillar sees potential for Cat autonomy in quarry and aggregates. Additionally, Caterpillar’s AHS technology has been deployed on the Cat 789D autonomous water truck (AWT) operating at Rio Tinto’s Gudai-Darri mine in Australia, the world’s first AWT, for automated watering of haul roads.

Rio Tinto details technology leaps at Gudai-Darri upon official opening

A week after delivering first ore, Rio Tinto’s Gudai-Darri mine, in Western Australia, has officially been opened, marking a major milestone for the company’s most technologically advanced mine.

Pilbara Traditional Owners, the Banjima People, and Western Australia’s Minister for Mines and Petroleum; Energy, Bill Johnston MLA, today joined Rio Tinto employees as well as valued partners and suppliers to celebrate the official opening.

Since development commenced in April 2019, more than 14 million workhours have culminated in the delivery of Rio Tinto’s 17th and most technologically advanced iron ore mine in the Pilbara. Development of the mine supported more than 3,000 jobs during the construction and design phase with the operation requiring around 600 permanent roles.

With an expected life of more than 40 years and an annual capacity of 43 Mt, Gudai-Darri will underpin future production of Rio Tinto’s Pilbara Blend™ product. It’s expected to increase iron ore production volumes and improve product mix from the Pilbara from the second half of this year, the company says. The mine is expected to reach capacity in 2023.

To optimise mine safety and drive productivity, Gudai-Darri features an unprecedented deployment of technology, much of it industry-leading. This includes the use of robotics for the ore sampling laboratory as well as for distribution of parts in the new workshop.

This goes from autonomous trucks, trains and drills, standard across many Rio Tinto mines in the Pilbara, to a full digital replica of the processing plant which allows teams to monitor and respond to data collected from the plant. The same digital asset data is used to provide a feature rich, interactive 3D environment for virtual reality training. These autonomous assets are monitored remotely from Rio Tinto’s Operations Centre 1,500 km away in Perth.

The technology spread includes 23 Caterpillar 793F autonomous haul trucks and three Caterpillar MD6310 autonomous drills. The trucks, in this case, implement real-time ore tracking using sensors to provide live dig face progression, while data-informed modelling from the drills helps to build more accurate assessments of existing ground conditions and improve safety. In collaboration with Caterpillar, Rio Tinto is advancing the development of zero-emissions autonomous haul trucks. Once development is complete, it is anticipated the world’s first operational deployment of Caterpillar 793 zero-emissions autonomous haul trucks will be at Gudai-Darri.

Gudai-Darri also hosts the world’s first autonomous water carts.

The new vehicles, developed in partnership with Caterpillar, are primarily used for dust suppression on site, enhancing productivity by enabling mine operations to digitally track water consumption and reduce waste. 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.

And, of course, it has autonomous trains under its AutoHaul™ system, which has been fully operational since June 2019.

The company has also invested in what it says is its first “rotable bucketwheel reclaimer”.

It explained: “Traditionally reclaimer maintenance requires a prolonged shutdown while several components are removed. This patented world first will enable the entire bucket wheel module to be changed out for maintenance, improving safety and efficiency.”

With the help of Scott Automation, the company has also introduced a robotic ore sampling lab on site, while its heavy mobile equipment warehouse is the home to four automatic guided vehicles.

Rio Tinto Iron Ore Chief Executive, Simon Trott, said: “We’ve worked closely with both the Banjima and Yindjibarndi People through the planning and development stages of Gudai-Darri and we look forward to partnering with them into the future to ensure the project achieves significant social and economic benefits.

“Gudai-Darri represents a step-change in the deployment of automation and technology within our iron ore business and a fantastic demonstration of the talent, ingenuity and capability that exists in Western Australia, a region which is now known globally for its technical excellence and innovation. Gudai-Darri’s combination of data and analytics, machine learning and automation, will make this mine safer and more productive.

“Gudai-Darri is our first greenfield mine in the Pilbara in more than a decade and a multi-billion-dollar investment in the State of Western Australia that will operate for decades to come.”

Western Australia’s Minister for Mines and Petroleum; Energy, Bill Johnston MLA, said: “I’m impressed by Rio Tinto’s innovation and sustainability; this is a prototype of the mine of the future. Once the new solar farm (a 34 MW farm consisting of about 83,000 panels) is complete it will be able to power one-third of Gudai-Darri’s operational needs with renewable energy.”

A total of A$3.2 billion ($2.2 billion) in goods and services were sourced within Western Australia during the construction phase of the Gudai-Darri Project with contracts valued at A$1.5 billion awarded directly to Western Australia-registered businesses such as NRW, Primero, DTMT Construction Company, Southern Cross Electrical Engineering and Monadelphous Engineering Associates.

This includes over A$100 million awarded directly to local Aboriginal businesses including White Springs, Lorrex Contracting, Hicks Civil & Mining, Brida, Karijini Development, Yurala Contracting Services, and Karlka FenceWright WA.

Hastings Deering tunes up New Acland coal mine’s Cat 793F fleet

Caterpillar dealer Hastings Deering has recently completed a full component change out on five of New Hope Group’s Cat 793F haul trucks working at the New Acland coal mine in Queensland, Australia.

The miner used the local Hastings Deering workshop in Toowoomba, Queensland, for the six-month undertaking, New Hope said.

“At A$2.2 million ($1.6 million) per truck, it sounds an expensive exercise but, with each truck costing almost A$5.5 million new, it was worth the expense,” New Hope said.

New Acland Maintenance Supervisor, Rob Trapp, said it was the first time the company had sent an entire fleet to the Toowoomba workshop.

“The guys and Hastings Deering have done work for us before, but this was by far the biggest job they have done for us,” he said. “It was a huge job, replacing basically every component on the truck. The fleet is only six years old but each had done about 24,000 h of work at the New Acland site. That’s slightly above industry standard so they were due for a tune-up.”

Service Manager at Hastings Deering Toowoomba, Justin Butcher, said: “This was a great win for us. We have around 100 workers at the Toowoomba Service centre and, of that, about 12 worked on this project basically around the clock.

“Each truck took three weeks and we had a week break in between each truck. We did what is known as a certified power train rebuild, which means we effectively stripped the trucks bare and replaced all the drive train components including the engine.

“In fact, apart from the cabin, tray and tyres, there isn’t much we didn’t either remove or replace.”

To get the 170 t trucks from Acland to Toowoomba, the company took off the cab, tray and wheels and loaded it into another big truck, according to Trapp.
