With a Vancouver-based headquarters and operational mines in the Philippines, the US and New Zealand, access to – and sharing of – data for decision making is critical for the optimisation of OceanaGold’s various operations and processes. It is also proving equally important for the company’s pursuit of recruitment and upskilling.

OceanaGold’s vision is to be a company people trust, want to work and partner with, supply and invest in, to create value. This vision comes alongside a plan to grow its gold production from 460,000-480,000 oz, to 580,000-600,000 oz in 2025, all while lowering its all-in sustaining costs.

Data is playing an increasingly important role in achieving this vision, with the company having invested heavily in digital and networking technology in the last few years.

For example, the company has made investments in industrial Wi-Fi across its operations – at the Golden Point underground mine (part of the Macraes operaton in New Zealand), Didipio (Philippines) and Haile (USA) – to improve access to data and company systems.

Michelle Du Plessis, Chief People & Technology Officer, told IM: “This investment is improving operational efficiency by reducing the need for people to leave operational areas of the mine to access data and systems.

“This also enables more of our equipment to be operated more safely and remotely.”

And remote operation of equipment has been growing with the installation of these network backbones, with teleremote underground drilling, loading and hauling in place at Golden Point with Sandvik fleets, plus teleremote loading and hauling – with Sandvik AutoMine®-equipped LH517is and TH551is – occurring at Haile.

There are also plans to switch to teleremote operations from a surface cabin at the Didipio underground mine.

The company is completing the real-time data process loop, with tablet-based mine operation control software – Digital Terrain’s Simbio solution – being implemented at all of its underground operations to, Du Plessis says, more accurately and effectively control underground mine planning based on what is happening in the mine at that time.

At the Horseshoe underground mine at Haile, the newest underground mine within the group, the company is also using digital and data platforms for its mine planning and short interval control systems, with the API-enabled integration coming into the Snowflake cloud-based ecosystem.

Du Plessis says these platforms are fully integrated with shift plans uploaded onto tablets and updated digitally if plans change through the shift.

On surface at the Macraes open-pit operation in New Zealand, the company is also working on the effective digital transfer of data, having recently migrated away from an older version of the Cat® MineStar™ Fleet FMS to MineSense for Miners’ (MS4M) FMS. “The main benefits were more accurate management of the fleet in terms of efficiency and maintenance planning,” Du Plessis explained of this change.

On surface at the Macraes open-pit operation in New Zealand, OceanaGold is now using MineSense for Miners’ (MS4M) FMS

Data access and availability is having a positive impact on operational productivity at OceanaGold’s operations, as well as enabling the company to confront the skills shortage it and every mining company is facing at the moment.

Du Plessis said: “At OceanaGold, we are taking a systematic and multi-pronged approach to skills development across the talent lifecycle. This guides the way we prepare our workforce for the future opportunities by building the data and technology capabilities across the company.

“We also have a distributed operational footprint, which allows us to draw on, and foster, talent in multiple jurisdictions and we can take advantage of workforce mobility between the operations.”

Some of the company’s operations are in regions where mining is not the major employer, and there are plenty of people with skills but no mining-specific experience. With OceanaGold prioritising a residential workforce and local employment over fly-in, fly-out options, skills development is crucial for resourcing its operations.

“To help us develop these skills and provide people an opportunity to build a career and have sustainable employment in mining, we partner with experienced training providers and contract mining companies,” Du Plessis explained.

For example, in the Philippines, OceanaGold has partnered with Site WorkReady (Philippines) Pty Ltd to use the Site Skills Training Center in Clark Pampanga. This facility allows the company to train new employees to work in an underground mining environment, with a focus on safety. “We are also looking at the opportunity to extend this partnership to include additional skills, such as automotive and heavy diesel mechanics, to continue to upskill our local workforce,” Du Plessis said.

In South Carolina, where the company has recently commenced mining from the new Horseshoe underground mine, OceanaGold has engaged Redpath Mining Inc in a similar skills development role.

“In addition to their mining contract, Redpath provide training and resources to develop the underground mining skills of the local workforce, allowing us to transition to a full owner-operator model over time,” Du Plessis explained.

The company has also invested in an underground training simulator at the operation, offering potential recruits exposure to the underground environment and building the operating skills of new trainees.

Thiess turning autonomous mining opportunities into reality

Thiess may have deliberately started small with autonomy, however, 10 years into its journey, the company is now being recognised as a mine automation leader in the ever-competitive mining services space.

Whether it is drilling, dozing or haulage, Thiess has plenty of autonomy expertise to offer.

The company started off in 2013 with maintenance and service work on the autonomous haulage fleet a major producer had assembled at its iron ore operation in the Pilbara. This has since broadened out to semi-autonomous tractor system (SATS) operations at major coal mines in Australia, autonomous drilling advances using Epiroc and Caterpillar platforms and, most recently, autonomous haulage and drilling operations at Pembroke Resources’ Olive Downs Complex greenfield operation in Queensland.

Trent Smith, Head of Autonomy and Operations Technology at Thiess, says the company seeks to involve itself early on with autonomy projects to ensure benefits can be realised.

He explains: “We like to help identify the opportunity for automation, which initially involves answering two big questions: is the application suitable? And does it deliver a financial benefit to the project? If there are positive answers to both questions, we try to work with those potential clients on how to bring the vision to life.”

Thiess’ involvement in this process is extensive, looking at network options, OEM selection, the “people element” and more, according to Smith.

“Our strategy was a bit different to others, where, aside from the work at our first autonomy project in the Pilbara, we started with small pilot projects on drills and dozers,” he told IM on the side lines of IMARC 2023 in Sydney earlier this month. “This enabled us to establish some solid foundations, understand the significance of the required changes, understand what the key enablers like networks were and put support models behind those aspects.”

To date, the mining services provider has worked closely with OEMs Epiroc and Caterpillar on modifying their autonomy platforms to fit its clients’ operations to improve safety and efficiency.

“With Caterpillar, we were able to take an emerging technology platform like Cat® MineStar™ Command for drilling and ensure it was fit for purpose for the coal environment we were planning to deploy it in.

“With Epiroc’s solution, we took a mature and proven product from the iron ore environment – equipped mainly for single pass, vertical drilling in competent ground with big and open drill pads – and tailored it for a coal application. This application required the introduction of autonomous rod changing and angle drilling for drilling in varied ground within tighter working areas.

“We worked hand-in-hand with Epiroc to understand the complexities of translating the solution for this environment, utilising all of the on-board data in the early trial stages and filtering that down to identify areas of waste and opportunity that could be used by the OEM and ourselves to realise an improvement in performance within that new environment.”

This evidently worked, with the companies, earlier this year, achieving the significant milestone of drilling more than one million lineal metres at the Lake Vermont coal mine in Queensland.

Pembroke Resources’ Olive Downs Complex has become the world’s first mining operation to deploy Command for hauling and Command for drilling solutions simultaneously

Thiess is also expecting to later this year reach the same autonomous drilling milestone with Cat’s Command for drilling platform; this time at a major coal mine in New South Wales.

The company has also helped achieve an industry first at Pembroke Resources’ Olive Downs Complex, with it becoming the world’s first mining operation to deploy Command for hauling and Command for drilling solutions simultaneously.

This assignment, which moved from concept to implementation of autonomous trucks and drills within a matter of 18 months, will ultimately include the deployment of 21 haul trucks (15 Cat 794 ACs and six Cat 793Fs) and three drills (Cat MD6310s) fitted with autonomous technology. Additionally, Thiess has established a private LTE network on Pembroke’s on-site communication infrastructure, enabling the safe operation of more than 85 connected assets within the autonomous operating zone. It has also upskilled more than 280 team members to, Thiess says, support the delivery of autonomous operations at Olive Downs to enable improvements in safety, operating hours, cycle efficiency and cost.

There is potential to add Command for dozing at Pembroke Resources’ Olive Downs Complex in future years, according to Smith.

“We have built the network and control room with the anticipation that this will be used,” he said. “We are already the first company in the world to have all three Caterpillar autonomy products running at operations, but Pembroke Resources’ Olive Downs Complex would be the first operation in the world to have all three Cat autonomy products operating at one mine.”

Thiess now has six autonomy projects out in the market, all of which are performing well against industry automation benchmarks, according to Smith, who says this capability is being recognised within the mining company community and OEM space.

The company has already announced its first automation project outside of Australia – at a coal mine in East Kalimantan, Indonesia, where it will deploy autonomous drilling operations – and Smith says the company is exploring further autonomous drilling opportunities in Latin America.

As well as continuing to engage with the wider OEM market on automation options, Thiess is working on different automation applications for existing products.

“With the SATS Command for dozing product, for instance, we are looking to take the platform and work with Caterpillar to move it towards a rehabilitation application,” Smith said, referencing the Thiess Rehabilitation business the company launched last year. “The requirements in mine rehabilitation are somewhat different to standard dozer push and stockpile applications, with multi-push vectors and the ability to potentially control several small-scale projects from one centralised hub.

“This is an example of where we work with an OEM, bring our knowledge of working with the product, identify a new application for the product, and then lay out what new set of capabilities need to be addressed to meet the requirements and fulfil that market opportunity.”

The company has a track record of proposing and advancing such autonomous dozing opportunities in certain niche applications, Smith said, adding that it recently achieved the 10 million cubic metres push mark with SATS.

The first rehabilitation application for SATS could end up being at a project in central Queensland – a project the Thiess Rehabilitation team started work on last year.

Thiess recently achieved the 10 million cubic metres push mark with SATS

Against this advancing autonomy backdrop, Smith says the company continues to be asked about combining the “decarbonisation” and autonomy pieces of the mine operating puzzle, with a staged approach typically being recommended.

“At the moment, these two (autonomy and decarbonisation) are a little bit separate, but they will converge at some point,” he said. “I imagine artificial intelligence and predictive capabilities will play a role in that – evaluating when the truck might run out of charge, when is best to pull that truck out of service for a 30-minute fast charge, etc.

“What I would say is if you have taken a step in either direction (autonomy or decarbonisation) already, you are well placed for this convergence.”

Smith offered up one last piece of advice to any company looking to take its next automation step: “Don’t forget the people and process part.”

He explained: “Most organisations know how to deliver a technology project, but I think the real value in automation is bringing the people and process along with that. Automation is a business transformation.

“We worked with Pembroke Resources’ at their Olive Downs Complex to ensure the appropriate change management process to enable automation was implemented across all business functions. Each function was reviewed to understand what needed to change to bring in automation and create a cohesive environment.

“It’s already starting to pay off at that project, where we exceeded our target of 6,500 annualised hours within two months of commencing autonomous haulage operations.”

Bingham Canyon to become first Rio Tinto site equipped with Cat MineStar Fleet

The Bingham Canyon copper mine in Utah, USA, has selected the Cat® MineStar™ Fleet management system as part of its plans to optimise open pit operations at the mine, owned by Rio Tinto, Caterpillar says.

Caterpillar Inc and Wheeler Machinery recently completed installation of a Cat MineStar Fleet management system at the mine, which, rather than upgrading the mine’s previous fleet management system, chose to deploy MineStar Fleet. This switch has, Caterpillar says, optimised the mine site’s equipment tracking, production recording, material management and truck assignment, and it has further expanded the technology relationship between Caterpillar and Rio Tinto.

Ryan Howell, Mining Technology Commercial Product Manager at Caterpillar, said: “For 15 years, Rio Tinto has used MineStar Terrain and has expanded its MineStar capabilities in recent years at locations like Gudai Darri and Marandoo, autonomous mine sites in Western Australia. Bingham Canyon Mine is the first MineStar Fleet site in Rio Tinto history, and this extends the company’s application of MineStar capabilities. Our team is proud of this MineStar Fleet system installation. We are honoured to be there to support the mine site’s fleet management needs.”

Joshua Wood, Principal Advisor, Surface Mining Centre of Excellence at Rio Tinto, added: “The close collaboration between the Rio Tinto Group team, Caterpillar, dealer and Kennecott ensured a successful deployment at Kennecott and their desire to be the flagship for future MineStar sites.”

Even though it wasn’t the easiest route for the mine, the cost-benefit analysis showed significant benefits long term using MineStar Fleet, including seamless integration with MineStar Terrain currently used by the mine, Caterpillar said.

Mike Gray, General Manager for Wheeler Machinery, said: “A true partnership with the supplier, dealer and customer allows for large-scale technology projects like this to be completed successfully with minimal impact to production.”

An incremental approach was devised to minimise the system installation loss-time impact on mining operations for bringing nearly 100 trucks, plus more than 40 supporting dozers, shovels and drills, online with MineStar Fleet. Caterpillar and Wheeler worked together to provide a quick turn-around time with best-in-class implementation, Caterpillar said.

Bryce Olson, Mine Monitoring and Control Superintendent at the Kennecott Bingham Canyon Mine, said: “We have been impressed with the partnership, and we share the same vision and have the correct team to get us there. We flipped the switch, and we haven’t gone backwards. We immediately started using MineStar Fleet’s open assignment, load-haul-dump and auto fuel advanced features.”

Cat MineStar Fleet automatically records and tracks data up and down a mine’s value chain, providing insights that help miners identify what is working and fix what is not to meet production targets, Caterpillar says. Fleet allows miners to view the entire operation at a glance on a computer and gain insights into key cost drivers – such as fuel, tyres, service parts and idle time – and improve haul fleet production and shovel utilisation.

Caterpillar boosts payload and speed with lower-emission R2900 XE LHD

The first diesel electric underground load-haul-dump (LHD) loader from Caterpillar, the new Cat® R2900 XE LHD, has officially been launched with a goal of meeting the underground mining industry’s needs for bigger payloads, faster loading and reduced emissions.

Built on the platform of Caterpillar’s most popular underground loader, this new LHD – which was previewed at MINExpo 2021 in Las Vegas – features optimised lift arm and component geometry plus load-sensing hydraulics to improve breakout force by 35% over the Cat R2900G, the company claims.

The world’s first R2900 XE has already been delivered to Western Australia-based gold miner Westgold Resources.

The R2900 XE works faster in tough conditions, delivering 52% quicker acceleration and improved machine response over the R2900G. It accelerates from 0-24 km/h in 6.4 seconds and achieves a 7% higher speed on grade, according to Caterpillar. Variable piston pumps deliver higher flow rates for faster hydraulic cylinder cycle times and powerful lift forces. Boasting a higher, 18.5-t payload for faster load times, the new LHD model offers a 3- to 4-pass match to the Cat AD63 truck for greater efficiency. Combined, these features deliver a 20% increase in productivity for the R2900 XE, Caterpillar says.

The loader’s redesigned buckets are available in four sizes with capacities ranging from 7.4 to 9.8 cu.m to match material density needs for a variety of loading, hauling and dumping conditions. Offering an optimised balance between productivity and bucket life, the full range of Cat ground engaging tools (GET) includes Modular Weld-on, Bolt-on Half Arrow and Durilock™ mechanically attached shrouds. To further protect the bucket, a range of heel shrouds, wear plates and bars are available in weld-on or mechanically attached designs.

The Cat C15 engine on board offers a variety of emission reduction and aftertreatment options, including an EU Stage V/US EPA Tier 4 Final configuration and diesel particulate filter. It delivers the power needed – up to 335 kW – with greater than 31% increased fuel efficiency compared with the R2900G. Its lower engine revolutions per minute results in reduced fuel burn, heat, noise, vibration and exhaust emissions, while offering an increase in power and productivity, according to Caterpillar.

High-efficiency electric drive

Drawing from decades of experience, the new R2900 XE LHD features a switch reluctance electric drive system. It is Caterpillar designed, integrated, validated and supported, and its continuously variable speed control delivers improved power and cycle times, Caterpillar says. With no driveline or powertrain shock loads, it offers smoother directional changing and implemented virtual gears for machine controllability. Automatic retarding controls maintain speed on grade. The drive system prevents coasting in neutral and combines with the anti-rollback feature to further increase operating safety.

Its new axle design offers increased component size and, together with the four-gear planetary final drive groups, provides greater strength and longer life. Larger wheel bearings and increased brake sizing further increase final drive life. Flange-mounted rims allow for safer tyre and rim changes. The differentials and final drives are built to withstand the forces of high torque and impact loads, providing high torque multiplication to reduce drivetrain stress. The traction control system, meanwhile, reduces tyre spin in difficult underfoot conditions to improve productivity, increase tyre life and reduce consumable costs.

The operator environment is built on Caterpillar’s R1700 platform, incorporating the latest improvements in productivity, safety and comfort. The cab’s enclosed design provides fresh, pressurised, temperature-controlled air circulation with air conditioning to enhance operator comfort and decrease fatigue. Resiliently mounted to the frame, the ROPS/FOPS structures isolate the operator from vibration for a more comfortable ride. The cab design incorporates two emergency exits, while available rearview and forward- and rear-facing side-view cameras help to improve visibility around the machine to enhance safety for operators and other workers.

Combining selection of direction, virtual gears and steering into a single lever, the standard STIC™ steering and transmission integrated control delivers maximum responsiveness and machine control, Caterpillar says. Low-effort, electric-over-hydraulic joystick controls feature simultaneous lift and tilt functions to optimise operating efficiency, while a two-pedal design with improved spacing and position facilitates more efficient foot control.

Caterpillar adds that the optional ride control improves cycle times and load retention when operating in rough terrain. By engaging/disengaging the ride control system at preset speeds, the system automatically dampens bucket forces and stabilises the machine, reducing fore and aft pitching motion. It incorporates a nitrogen/oil accumulator system in the lift circuit to act as a shock absorber.

Scalable technology solutions

The new R2900 XE ships from the factory equipped ready for Cat MineStar™ solutions, a comprehensive suite of technology offerings. From machine health monitoring to fully automated haul and dump cycles, scalable levels of technologies can be tailored to meet each mine site’s unique needs, Caterpillar says. Standard Product Link™ Elite boosts machine connectivity by enabling the loader to collect and transmit health and condition monitoring information into locally or cloud-hosted applications.

Mine sites can choose between a range of available MineStar technologies, including:

  • Command for underground – enables remote operation of LHD machines, from line-of-sight to full autonomy, allowing operators to be relocated to a safe, comfortable location to improve productivity, efficiency and safety;
  • Detect for underground – uses peer-to-peer proximity detection to reduce the risk of unintended interactions between people and machines by “seeing” in the dark;
  • Fleet for underground – gives real-time access to accurate information such as cycle time, payload, machine position, and other key operational parameters and automatically tracks and records data up and down the value chain; and
  • Health – collects and transmits equipment data necessary for proactive maintenance services and predictive equipment analysis.

New Autodig technology optimises loading by automating crucial parts of the digging cycle, Caterpillar says.

“When combined with Command for underground, Autodig offers a true automated machine, providing high-speed auto tramming and full cycle autonomy,” the company explains. “Featuring an onboard payload weight scale, Cat Payload Management provides material management, cycle count and timing recording, and wireless production detail reporting capabilities. Optional tyre pressure monitoring is fully integrated into the R2900 XE, allowing operators to determine on-the-fly if the tyres are properly inflated.”

With more robust structures, increased powertrain durability, longer lasting components, improved maintenance and extended service intervals, the new R2900 XE can be maintained in less time, helping to lower cost-per-tonne operation, Caterpillar says. The machine’s electric drive reduces the number of moving parts compared with traditional mechanical drive systems. Extended oil change intervals, together with the electric drivetrain, reduces the amount of oils used. Sight gauges visible from ground level simplify fluid level checks, and all filters are positioned vertically to provide spill-free servicing, Caterpillar claims. Electrical connectors are sealed to lock out dust and moisture, while harnesses are covered for protection.

Machine design eliminates castings and reduces weight to increase the life and strength of the frame without sacrificing performance. The frame, powertrain, engine and components are built to be rebuilt using new, remanufactured, or rebuilt parts and components, allowing mines to take advantage of multiple lives of like-new performance to lower operating costs.

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.

Caterpillar to introduce battery-electric and autonomous haulage tech at Newmont ops

Newmont has announced a strategic alliance with Caterpillar Inc to deliver a fully connected, automated, zero carbon emitting, end-to-end mining system that will see the introduction of first-of-a-kind battery-electric haulage technology and automation at the gold miner’s Cripple Creek and Victor and Tanami mines in the USA and Australia, respectively.

The announcement comes a day after Newmont’s Executive Vice President and Chief Technology Officer, Dean Gehring, told the Energy and Mines Virtual World Congress that the company’s primary focus for decarbonising its mobile mining fleet was on battery-electric options. It also follows the deployment of autonomous haulage solution technology at the Boddington mine in Australia (control room, pictured).

Together, the two companies will collaborate to create a safer, more productive mine, and substantially support Newmont in reaching its 2030 greenhouse gas (GHG) emissions reduction targets of more than 30%, with an ultimate goal of being net zero carbon by 2050, the companies said.

Tom Palmer, President and CEO of Newmont Corporation, said: “A year ago, Newmont announced industry-leading emission reduction targets because we understand the human contribution to climate change. We followed with a commitment to invest $500 million over five years to identify pathways forward as we firmly believe that we must make bold, lasting commitments to achieve the necessary change for a bright, healthy future.

“Today, we furthered that commitment by announcing a new strategic alliance with Caterpillar to address climate change by fundamentally changing the mining industry through the rapid development and implementation of a comprehensive all-electric autonomous mining system to achieve zero emissions mining.”

Newmont’s surface and underground mining fleets are responsible for approximately 40% of the company’s carbon emissions, and building a new model for surface and underground mining is critical to delivering on Newmont’s emissions reduction targets, the company said.

Newmont will also be supporting Caterpillar’s validation of evolving features and functionality within the MineStar suite to be deployed across Newmont’s surface and underground assets globally. This deployment facilitates centralised production and asset management.

“Caterpillar is committed to providing transformational advancements in safety, sustainability and technology,” Jim Umpleby, Chairman and CEO of Caterpillar Inc, said. “We share Newmont’s dedication to a reduced-carbon future, and we’re honoured to work together on this industry leading effort.”

(From left to right) Rob Atkinson, Executive Vice President and Chief Operating Officer, Newmont, Tom Palmer, President and CEO, Newmont, Jim Umpleby, Chairman and CEO Caterpillar Inc, and Denise Johnson, Group President, Caterpillar Inc

Under the agreement, Newmont plans to provide a preliminary investment of $100 million as the companies set initial automation and electrification goals for surface and underground mining infrastructures and haulage fleets at Newmont’s Cripple Creek and Victor (CC&V) mine in Colorado, USA and Tanami mine in Northern Territory, Australia. The goals include:

  • Introduction of an automated haulage fleet of up to 16 vehicles at CC&V planned through 2023, with a transition to haulage fleet electrification and implementation of Caterpillar’s advanced electrification and infrastructure system with delivery of a test fleet in 2026. Actions include validating first-of-a-kind battery-electric haulage technology in the years prior to full production of autonomous electric haulage equipment;
  • Caterpillar will develop its first battery electric zero-emissions underground truck to be deployed at Tanami by 2026. The deployment includes a fleet of up to 10 battery-electric underground haul trucks, supported by Caterpillar’s advanced electrification and infrastructure system. This includes first-of-a-kind battery electric haulage technology for underground mining in 2024, the introduction of battery autonomous technology in 2025, with full deployment in 2026.

Together, Newmont and Caterpillar plan to validate equipment, infrastructure, technologies and processes to transform both surface and underground mining, focusing on safety, automation, decarbonisation, optimisation, data and asset management across Newmont’s global operations, the miner said.

“Leveraging Newmont’s scale and operational capabilities, the alliance sets the stage for the rapid development and deployment of the technologies, ultimately improving safety, productivity and energy efficiency across the mining industry,” it added.

Cat to bolster MineStar Edge platform with Guide and Surface Management additions

Automation, IoT, Mining equipment, Mining safety, Mining services, Mining software, , , , , , , , ,

Caterpillar has added two new capabilities to its cloud-based MineStar™ Edge platform – MineStar Guide and Surface Management.

Accessed alongside Equipment Tracking and Production Recording data from the same office computer or tablet in the field, the additions further augment the Cat® MineStar Solutions suite of technologies.

Edge, Cat says, features the latest technology advancements to measure, manage and optimise mining operations. Using data fusion, machine learning and artificial intelligence, it continues to grow as it collects data, identifies patterns and learns to make decisions.

Guide, available in early 2022, serves as a new platform for high-precision on-board, while Surface Management is an enhanced office platform for Guide, which is currently in development.

Using the advanced capabilities of the Edge platform and the most advanced GNSS technology, MineStar Guide provides the next generation high-precision system for grading and loading operations, according to Cat. Real-time feedback improves operator efficiency and increases machine production.

Featuring a new user interface inside the machine’s cab, Guide offers intuitive operation, which makes it easier to train new operators. Its on-board, dual-receiver system offers improved machine heading and data to increase grading and loading efficiency.

Working through enhanced 3D grade control and design visualisation, Guide provides high-precision block and material identification that is automatically provided to the operator and operations. Grade, block and material designs are also automatically sent to the machine, based on location, to ensure compliance to plan, increase productivity and reduced rework.

Guide offers “stakeless” ore control and regular elevation updates, reducing the need for surveyors in the field to improve safety, Cat says, with the company claiming the enhanced level of automatic blade control provided by Guide will help reduce operator fatigue when grading to design.

Operator and production key performance indicators are sent to the machine through MineStar Edge, empowering operators to stay on schedule.

Guide demonstration units were installed on the Cat 992 wheel loader, Cat 6060 hydraulic mining shovel cab and Cat 24 motor grader displays, as well as inside the technology area, at the recent MINExpo 2021 event in Las Vegas.

3D planning with MineStar Surface Management

Accessed through the integrated MineStar Edge platform, new MineStar Surface Management delivers to the field planning and material information created in the office, Cat says. The next-generation grading and loading platform leverages data provided by Guide-equipped machines for precise execution of planned versus actual production.

With the new Edge platform, Surface Management allows reports to be viewed on office computers or in the field on laptops and mobile devices. Its 3D visualisation of virtual and augmented reality substantially improves project progress viewing, Cat says. The mobile platform gives users the ability to zoom and rotate on particular areas of the site for a more detailed view.

“A powerful material management tool, Surface Management automatically generates fused digital modelling from multiple data sources for improved accuracy,” the company said. “It tracks haul roads, dumps, loading areas and other truck destinations.”

Users can review designs, blocks in progress and as-built areas. Reporting capabilities include timeline advance and comparison with swipe to previous or future and volume calculation. Increasing program flexibility, Surface Management gives customers the freedom to choose the reporting method, according to Cat.

Cat says dozens of mine sites rely on Edge’s Equipment Tracking and Production Recording capabilities with fleet installations ranging from fewer than five to more than 80 machines.

Caterpillar has updated its 7495 and 7495 HF electric rope shovels with the result being an up to 10% increase in operating efficiency.

Drawing from more than a century of rope shovel innovation, the 2021 Cat® 7495 and 7495 HF Electric Rope Shovels (ERS) combine multiple standard feature upgrades to improve machine productivity, while component enhancements, increased frame durability and improved serviceability help reduce cost per tonne of material moved by as much as 15%.

Dan Wyatt, ERS Product Value Stream Manager, said: “Consistently, our customers tell us machine availability and productivity are primary contributors to their operation’s success. From the full adaptive control system for HydraCrowd™ to more innovative technology and data security, the advances made to the 2021 electric rope shovels reflect our commitment to meeting their needs.

“Many of these improvements are compatible with shovels in the field, so customers can realise these gains through upgrades to their existing fleets as well as new machine purchases.”

A new propel gear case for the 7495 and 7495 HF models nearly doubles the life of propel gear cases in some extreme operating conditions, Cat claims. Precise adjustments to gearing geometry and advancements in tooth hardening enhance gear case durability and productivity. The result is lower total cost of ownership of as much as $8/h when the drive system is replaced at one scheduled time.

Additionally, an ecology drain simplifies oil draining and enables kidney-loop flushing, which reduces abrasion-causing contaminants and oil change frequency.

Updates to the 7495 AC electric drive system deliver greater reliability, improved maintenance access, enhanced safety, and expanded high altitude and temperature capabilities, the company says. A liquid-cooled motion regulator cabinet efficiently dissipates heat generated by electrical components and enables operation at -40°C to +50°C and altitudes as high as 5,250 m without derating.

A faster propel transfer switch cuts lag time by 75% to improve productivity, while common motors in multiple applications means fewer parts to stock, improved parts availability and simplified maintenance, Cat says.

A reconfiguration of the crawler carriage allows drive shaft and tumbler replacement from the outboard side without removing the propel transmission. This slashes maintenance time by days while enhancing safety, Cat says. With this design, thrust loads are evenly distributed on large, tapered roller bearings rather than bronze thrust plates, increasing durability to align with 25,000-hour planned rebuilds, even in harsh environments.

Stress from every load passes through the shovel’s swing rack. This is where an enhanced design includes a single-piece rail casting that eliminates vertical segment cracks to increase durability. The rail provides a uniform path for roller movement, preventing rollers from coming loose and creating irregular wear patterns. The upgraded third rail improves access for inspection and retightening, in addition to providing added support to the thrust rail during operation. New swing girder bushings and girder-to-chassis shim designs offer improved access, reducing service time.

“All major rope shovel structures are built with high-strength steel and rugged castings, joined and thermally stress relieved to deliver reliable operation in harsh mining conditions,” Cat says. “Full penetration, profiled and ground welds are made at critical junctures, and MT, UT and X-ray inspections ensure weld quality. Structures are stress-relieved to prevent cracking, and white painted interiors facilitate inspection.”

Both the 7495 and 7495 HF ERS models now offer a full Cat bill of materials, streamlining the parts ordering process and improving parts availability, the company says.

Technology increases efficiency

Both the 7495 and 7495 HF come standard with Product Link Elite™, which transmits critical machine operating data such as utilisation, location and condition via cellular or site internet connection. Added router functionality helps to protect data security. Advanced productivity tools within Product Link Elite enable a cycle segmentation algorithm, and the combined data allows for advanced analysis of productivity, Cat says.

When linked with the available Cat MineStar™ Fleet, real-time machine tracking produces a comprehensive overview of all equipment assets to assist with fleet management and productivity.

Providing real-time feedback to improve loading efficiency, available MineStar Terrain uses guidance technology and an in-cab display to deliver precise dipper position guidance. Optional MineStar Health delivers critical event-based machine condition and operating data, while its advanced diagnostic and analytic tools improve service efficiency, the company says.

The standard Operator Assist – Enhanced Motion Control simplifies machine operation to promote high production while protecting the machine. This system is designed to yield more reliable crowd rope replacement schedules, full design life for hoist ropes, reduced wear on crowd brakes and longer life for hoist gear case components, according to Cat

HydraCrowd

A new adaptive control system (ACS) – a final piece of a multiphase enhancement initiative for HydraCrowd – delivers up to 25% cost savings on the ACS valve, resulting in up to 5% total cost of ownership saving for the entire system, Cat says. Lower initial costs, rebuildable elements and improved accessibility combine to reduce the time required for replacements. The new design also increases reliability without significantly changing the HydraCrowd maintenance schedule, according to Cat.

The new circulation filter employs two smaller, easily accessed filters that do not require roof panel removal for replacement. More affordable than the previous single-filter design, the new configuration also reduces replacement time, Cat says.

A new filter placed at the pump drive transmission improves filtration of the lubrication fluid, helping to extend the life and reliability of the system by reducing contaminants and decreasing wear. The new pump drive transmission filter assists in reducing unplanned maintenance events to decrease downtime.

Caterpillar says it is leading the way in the next generation of productive hauling through game-changing efficiency advancements with the Next Generation of Cat® Mining Trucks.

The 785 large mining truck was Caterpillar’s first entry into the mining industry more than three decades ago and, the company says, has been a top performer on sites around the world ever since. It is fitting, therefore, that it is the first of a new generation.

Designed by operators, for operators

“Where does the next generation of productive haulage begin? It all starts with operators, who work in an environment designed for them by other operators,” Cat says.

Truck operators provided input, worked alongside Cat’s large mining truck design team and shared feedback to help create a state-of-the-art environment on board the 785 designed for efficiency and ergonomics, and equipped with features that increase comfort, automate functions and boost confidence, from the smallest operator to largest operator around the globe, the company said.

The next generation operator experience is safer, more consistent, more predictable and more intuitive, shortening the learning curve and boosting productivity of less experienced operators, according to the company.

The new speed coaching feature gives operators real-time feedback on how to operate the truck to maximise its productivity, Cat told IM. In field trials, the new AutoHoist controls, meanwhile, have shown reductions of up to 12 seconds in the dumping cycle. “This feature can also reduce fuel burn during this portion of the haul cycle,” the company said.

Features such as Hill Start Assist, Anti Roll Back, Enhanced Traction Control, Dynamic Stability Control, Anti-lock Brake System, Machine Speed Limiting and Cruise Control improve machine responsiveness and controllability, while improving cycle times and reducing operator fatigue, the company added.

Serviceability and reliability

In addition to enhancing the operator experience and efficiency, the next generation truck platform delivers significant improvements in serviceability and reliability, according to Cat.

“We’ve worked to reduce key contributors to downtime with features like the new modular HVAC (heating, ventilation and air condition) system, which improves reliability and consolidates components so the entire system can be removed and replaced quickly,” Cat said.

Field studies have shown this modular element alone can improve physical availability by up to 0.5%.

New “Remote Flash” and Remote Troubleshooting capabilities reduce downtime and maximise machine availability, according to Cat, providing the ability to troubleshoot the machine remotely or update the software of an electronic control module on an engine or machine through cellular service.

“A manager in the back office can securely push machine software updates over the air to the truck,” Cat explained. “This feature reduces machine downtime and technician time, allows updates to be performed when most convenient, and keeps the machine up to date with the most recent software.”

Connectivity and technology integration

Mine sites have access to real-time information and analytics that improve their total cost of ownership, the company claims, with these next gen pre-production machines “quantifying the full value of new features” at multiple customer sites right now ahead of the start of manufacturing in the March quarter of 2021, Cat says.

Cat says it will be easier to integrate Caterpillar and certain third-party current and future technology solutions on the next generation platform, with offerings such as Cat MineStar™ – which includes fully autonomous haulage with Command – able to deliver a step change in productivity, efficiency and safety.

This integration can provide valuable data and analytics to enable near real-time decision making, maintenance troubleshooting, and the ability to predict and proactively prevent failures, according to the company.

Included on the truck is an improved payload monitoring system that comes with more accurate measurements, improved monitoring and an improved interface, according to Cat.

“Information is more accurate and the system provides access to more data,” the company said of this system. “The new system also provides accurate dipper counts, reduces false loading triggers and overload detection, while carryback calculations are more accurate.”

The system also provides detailed haul cycle segmentation and remote access through telematics, Cat added.

The backbone of advanced connectivity on the Next Gen truck platform is the ability to communicate through dual mode cellular 4G/LTE and Satellite, or local Wi-Fi networks – “whatever benefits the mine plan”, Cat says.

“Next generation connectivity delivers faster data transfers, better access to data, consistent and reliable data communication, more insightful and actionable data, improved data analytics and new diagnostic capabilities,” the company explained.

“The NextGen telematics systems can collect and transmit information securely into locally-hosted or cloud-hosted applications, such as Cat MineStar Fleet, MineStar Edge, and Health Equipment Insights. These applications boost productivity and improve maintenance and machine life.”

Built on a solid foundation

With nominal rated payload of 138 t or higher with optional larger tyres, the 785 has delivered lowest cost per tonne in a wide range of mining applications ranging from flat hauls to deep pits, and solid roadways to challenging underfoot conditions, the company said.

Its 3512E engine offers selectable power options so miners can either match the speed of their current fleet or speed up their cycle times, according to the company. The optional Tier 4 engine has shown a reduction in fuel usage by as much as 9%, while advanced electronic transmission controls deliver faster cycle times, faster acceleration, less spillage and reduced haul road maintenance, on top of improved engine and powertrain life. Longer-life components, extended service intervals and easier maintenance contribute to higher mechanical availability.

“The individual features, components, software and systems that make up the Next Generation 785 have one very important thing in common: they are all manufactured by Caterpillar and supported by the Cat dealer network.

“This integration ensures that the entire truck, from tyres to transmissions, engines to electronics, can be fully optimised to deliver the lowest cost per tonne in any manned or autonomous site applications in the world.”
