WesTrac and its subsidiary Hushpak have delivered what they say is as an innovative sound suppression solution to The Bloomfield Group that has reduced the noise output of 19 Cat 793F mining trucks.

Managing the sound output from heavy machinery can be a challenging task on mine sites, but this is starting to become easier for many businesses, according to WesTrac.

“That’s thanks to a range of innovative sound suppression offerings from leading Caterpillar dealer WesTrac, which in the last two years has delivered 19 Cat 793F large mining trucks to Hunter Valley-based mining customer The Bloomfield Group showcasing these capabilities,” it said.

Using a combination of Caterpillar factory options and inhouse, customised solutions, WesTrac was tasked with reducing the noise of the Cat 793F trucks to levels that aligned to Bloomfields’ requirements at its Bloomfield and Rix’s Creek mines – in close proximity to Maitland and Singleton, respectively.

According to WesTrac NSW Strategic Growth Manager, Alan Corcoran, the solution achieved that goal on time, within budget and included several requested customisations.

“Working with our subsidiary Hushpak, we devised a solution that passed the sound output tests in the first instance,” Corcoran says.

Hushpak is a standalone engineering business specialising in sound suppression and attenuation on both mobile and fixed plant. WesTrac acquired the company in March 2022.

“Sound comes from various outputs, particularly on mobile plant,” he explains. “The engine, transmission, fan, hydraulic pumps and various other components compound to make these large machines quite noisy.

“Caterpillar offer ready-to-order sound suppression kits for mining machines, but, in some cases, there are gaps in the product offering. Many of our customers have unique needs, especially in areas like the Hunter Valley, where mine sites are in closer proximity to towns and residential areas.

“These customers have additional requirements that need further sound suppression. Meeting these unique needs, on all types of mining equipment, such as this customer’s 793F trucks, led to this project to bridge the gap.”

*“These 793Fs are a 20-year investment for our business and are setting the foundation for our haulage fleet moving forward,” David Worboys says*

Such is the case for Bloomfield, which produces around 2.5 Mt/y of saleable coal from its mines in New South Wales, where all haulage and ancillary machinery fleet are Cat products.

Following extensive market research carried out in 2020, Bloomfield Plant and Equipment Manager, David Worboys, and his broader team settled on the 220-t-class Caterpillar 793F truck and have since taken delivery of 19 units from WesTrac’s Tomago branch, now working at Rix’s Creek and Bloomfield mine.

Worboys says all trucks fitted out with the Hushpak-engineered sound attenuation package were contributing to ongoing site noise compliance and minimising impact to nearby communities.

“We pride ourselves on being good neighbours, and therefore we make every effort to minimise the noise impacts on them,” he says. “We use engineering best practice where we can, to achieve as high sound output reduction as we can.

“These 793Fs are a 20-year investment for our business and are setting the foundation for our haulage fleet moving forward.”

With that in mind, WesTrac’s equipment specialists and engineers worked with Hushpak and Bloomfield to develop a customised solution for the 793F that took airflow, weld locations, centre of gravity, visibility and access for maintenance into consideration.

On completion of the first 793F fit out, WesTrac engaged an independent tester to assess the noise output. Testing was carried out at WesTrac’s NSW headquarters in Tomago.

Following delivery of the first two trucks to site, WesTrac and Hushpak continued to work with Bloomfield to administer minor adjustments that have been carried through to other trucks delivered.

“Through collaboration, using expertise from us on site and working with WesTrac and Hushpak to come up with solutions introduced into the sound attenuation package has ultimately delivered a great product,” Worboys says.

Corcoran said WesTrac’s ability to tailor solutions to meet customer requirements as well as broader requirements such as emission reduction targets fuels the company’s continuous improvement program.

IAMGOLD has released its latest quarterly results, highlighting the significant progress it has made on its majority-owned Côté gold project in northeastern Ontario, Canada.

The company is the majority owner and operator of Côté, with the next biggest stake owned by Sumitomo Metal Mining. Côté has a mine life of 18 years, and will produce an average of 365,000 oz/y over this term. Some 236 Mt of ore will be mined, along with 568 Mt of waste, with an average processed grade of 0.96 g/t Au.

In the latest results, IAMGOLD said the project was estimated to be 85.7% complete as of the end of June. Since commencement of construction, $2.23 billion ($1.56 billion at the 70% held by IAMGOLD) of the planned $2.965 billion ($2.08 billion at 70%) of project expenditure has been incurred.

Autonomous operations have been incorporated into the Côté mine design with a focus on early operations readiness. The Autonomous Control Room equipped for Caterpillar Command for hauling was completed in mid-September and the project achieved a major milestone in January with the initial deployment of the autonomous 231 t Cat 793F CMD haul trucks working with Toromont Cat. On January 22, the mine saw the safe operation of a full load, haul, and dump cycle using autonomous dump trucks.

During the June quarter 2023, up to seven Cat 793F haul trucks have begun operating in autonomous mode and a total of 14 haul trucks have been commissioned. Autonomous drilling with two Epiroc Pit Vipers began in this quarter, with a third nearing commissioning completion. In total, the company is expected to operate six autonomous Epiroc Pit Viper 231 blasthole drill rigs, complemented by two Epiroc D65 SmartROC crawler rigs, which will be remote operation ready.

In addition it will deploy electric Caterpillar hydraulic shovels – namely two 6060FS units, AC-powered via tethered cable.

The company said owner mining has progressed well with nearly 1.1 Mt mined in the June quarter. The stockpile has approximately 2 Mt of material on track to the target build-up of 5 Mt by the end of the year. The IAMGOLD mine operations team started operating 24/7 effectively in July.

The project timeline remains in place, with production expected to commence in early 2024.

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.
