RCT develops agnostic speed limiting solution for underground trucks

RCT has devised an agnostic speed limiting solution for underground trucks following a recent approach from a mine in Western Australia.

The mine recently approached RCT for this for three of its newly acquired underground trucks and its operators at its mine site.

The trucks were equipped with seven gears from factory settings, and the client wanted to be able to control the speed of the trucks while underground to ensure safety of operators and the mine itself.

“In order to speed up trucking tonnes-kilometres the client wanted to speed limit the trucks underground but have the operators to still be able to utilise all of the gears at a higher speed while on the surface,” RCT’s Account Manager, Scott Phillips, said.

The state-of-the-art safety solution is fully programable with four speed settings available to suit individual needs to various situations and speeds. The tamper-resistant design also conveniently interfaces directly into a machine throttle circuit.

In addition, a Geo-Fencing kit was implemented on site to further control the trucks speeds in different locations and a proportional retarder control system to make sure the truck maintains a constant speed no matter the gradient it is manoeuvring on.

With speeding being widely recognised as a major contributor to light vehicle accidents in mine sites around the globe, this solution is well sought after in the mining industry, according to RCT. In addition to reducing incidents, it also helps to lower fuel consumption.

The client has been so impressed with the speed limiting solution that it has already ordered three more to be installed on more trucks operating on site, RCT says.

As with all RCT’s solutions, the Speed Limiter is agnostic and is suitable for all makes and models.

Epiroc focused on ‘connecting the dots’ to create mine of the future

Ahead of Epiroc’s Capital Markets Day (CMD) and MINExpo 2024 at a hotel just outside of Las Vegas, Helena Hedblom, Epiroc President and CEO, was happy to tackle the industry’s big three: automation, digitalisation and electrification.

Hedblom, like the heads of her fellow OEMs, has big ambitions for these three technology pillars, but the way Epiroc is looking to meet these ambitions is different.

The company’s “agnostic” philosophy has been a key differentiator for the past years, and even as more OEMs start to open up their architecture and platforms to the wider vendor marketplace, it is this attitude that is likely to help it lead from the front.

“Our ambition is to provide mixed fleet automation,” Hedblom told IM last week. “That is what we have invested in quite heavily over the last two years; we have acquired two companies in RCT and ASI Mining to allow us to achieve this.

“This is how we see the future of mining when it comes to automation, having the capabilities to operate whatever type of equipment there might be in that mine, including utility vehicles.”

Epiroc has, as of the CMD last week, 3,100 machines running without drivers. This is up 29% from the last CMD in June 2023, with the company noting that there was “great potential to connect an even larger fleet” via Epiroc machines and/or units from other OEMs.

RCT, underground, has a track record of achieving such autonomy on a wide range of machines, while, on surface, ASI Mining has proven it can do the same with the fleet at Roy Hill, in Western Australia.

Epiroc is currently converting Roy Hill’s mixed fleet to driverless operation in Australia, with 78 autonomous haul trucks made up of Caterpillar and Hitachi trucks, and over 200 utility vehicles.

Roy Hill remains the sole case study on surface, but Hedblom says the company will soon transition to the ‘scale’ of its “nail and scale” process that leads to adding more mine sites to its agnostic automation platform.

Hedblom is convinced the ability to automate the entire fleet – whether the machines are “digitally connected” or not – plus integrate the highest levels of collision avoidance solution, will go far in eradicating the need to allow autonomous and staffed equipment to operate in the same zones underground and on surface.

“If you have all the utility vehicles automated, that is the key,” she said. “It is more than just automation; through the Mernok acquisition, we’re now able to bring in Level 7, 8 and 9 collision avoidance technologies.

“Technology-wise, it is all coming together.”

Electrification

The big stats in terms of electrification include:

  • 42% of the offering in “fossil free” versions;
  • Battery-electric vehicles deployed at 34 sites;
  • An active electric fleet of rigs, loaders and trucks totalling over 600 units (of which a large portion is historical fleet, including cable);
  • Recurring battery-electric vehicle orders from 12 sites; and
  • A three times increase in the utilisation rate of battery-electric vehicles during the last 12 months.

The other statistic of note is that, as it stands, Epiroc group revenues related to electrification amount to just 4%.

This indicates both Epiroc and the industry are still in the initial stages of this transition; an opinion backed up by claims from the Electric Mine Consortium that Sandvik’s battery-electric truck population across the globe represents only 15% and, as it stands, no battery-electric load and haul equipment has been sold commercially in one of the biggest underground markets: Australia.

Hedblom, here, sees parallels with the automation uptick in the industry.

“This transformation is happening in the same way that automation evolved,” she said. “A couple of years ago, we had some customers that had greenfield operations and decided to go fully electric. Now we see more customers looking at repeat orders.”

The automation analogues also come with the fact that Epiroc – unlike other OEMs – is offering a mid-life rebuild option to convert some of its existing diesel-powered load and haul fleet to battery-electric operation.

Epiroc has plans to offer this conversion option across its full existing diesel-powered load and haul fleet by 2030.

The addition of ‘fossil free’ in the Epiroc lexicon over the last few years reflects the need to put multiple options on the table for miners.

“We see that there will be different types of solutions needed during the coming 10 or 20 years, depending on mining method, type of application, etc,” Hedblom said.

This was made apparent on the floor at MINExpo where Epiroc showcased the MT66 S e Drive, a Pit Viper 271 E and a SmartROC D65 BE. The former is a diesel-electric haul truck that uses both diesel engine and electric drivetrain to reduce fuel consumption and emissions, the SmartROC D65 is a battery-electric down-the-hole drill demonstrator that trams on battery yet is plugged in for drilling, while the Pit Viper 271 E is currently envisaged as a unit connected to the site’s renewable electricity infrastructure for that ‘fossil free’ operation.

The Minetruck MT66 S e Drive

“We believe there will be a combination of different energy sources in this mix,” Hedblom said, reeling off the likes of battery-electric, cable, trolley and hybrid options. Additionally, biofuel ‘drop-in’ solutions are already available for conventionally powered machines in its offering.

She added: “Sometimes the discussion is all about benchmarking diesel against a fossil-free machine, but the reality is that every machine we are developing now cannot just be on par with its diesel counterpart. It must be better – faster up the ramp, filling the bucket faster, etc – to ensure we provide productivity benefits and a lower total cost of ownership for customers.”

Digitalisation

From an M&A perspective, digitalisation has been a key focus area for Epiroc since the Atlas Copco spinoff in 2018, with many of the 27 acquisitions since listing tied to this trend.

This, as well as many organic initiatives, has led to the company building up a revenue base for its Digital Solutions division of SEK2.4 billion ($234 million).

“Our digital solutions are agnostic, working on different types of machines and systems, so this opens up many ways to engage with our customers,” Hedblom said, noting that the platforms it had created are being used by existing Epiroc equipment customers, as well as those with fleets from other OEMs.

“The areas of high interest are around collision avoidance, situational awareness and mixed fleet automation,” she said. “I see that digitalisation creates that transparency needed to drive productivity.”

Digitalisation, itself, represents an easier ‘sell’ for Epiroc due to its seamless nature – ie not creating multiple change management issues – when compared with adopting automation and electrification technologies, Hedblom added.

Going forward, she is convinced a digital backbone will become more important with the increasing uptake of automation and electrification.

“Today, a lot of the different tools mining companies are using – for the mine plan, for maintenance, etc – are still not connected,” she explained. “You don’t use all data at the same time for the best type of decision.

“A lost hour of productivity is a lost hour of productivity; we are seeking to avoid this through increased digitalisation.”

This is where the individual solutions Epiroc has acquired through the likes of Mernok (collision avoidance), RCT and ASI Mining (agnostic automation solutions), Meglab and JTMEC (battery-electric chargers and infrastructure) could combine with its digitalisation platforms to optimise the overall mining process.

“By connecting the dots, there are many more optimisation opportunities to be had,” Hedblom said.

The difference here is that Epiroc is willing to look outside of its own four walls to the broader industrial space to ‘connect these dots’, meaning the idea of a fully-electric, fully-autonomous, fully-digitalised mine could be much closer to becoming a reality.

RCT boosts automation capabilities of Jevons Robotics ARTEV6000 explosives/stemming unit

Jevons Robotics can now deliver explosives or stemming via its ARTEV6000 product using RCT’s remote control set either via line-of-sight or teleremote control, RCT reports.

Implementing this technology has eliminated the need for personnel to conduct quality assurance or load the blast holes manually, removing exposure hours associated with highwalls, cavities and fatigue. The company has been demonstrating this to interested parties via pilot unit at the Australian Automation and Robotics Precinct in Western Australia.

RCT’s Custom Manager, David Wright, said this project was different to any job done before and, therefore, its specialised bespoke department was given the job.

“It is the first time we have remote controlled this type of vehicle carrying out this job scope,” he said. “We were able to use standard loader code, getting it on the machine and talking to the machine.”

The job, in its manual state is well-known as being high risk, which also makes the role difficult to not only recruit for but then retain the staff.

“The great thing about the Jevons platform is that it can be used for a variety of applications on a mine site to remove additional hazards and its flexibility is something that will bring great value to the industry, so we were so pleased to be able to work together on it,” Wright added.

Jevons Robotics CEO, Todd Peate, said that when Jevons was looking for a teleop and line-of-sight capability, it was immediately drawn to the established competency of RCT and its deep experience in mining.

“We wanted a solution that eased our customers mind on automating this process and we certainly have that with RCT,” he said.

RCT collaborates with Barminco on latest automation project at IGO Nova

Today, RCT’s agnostic automation can be found at many of Barminco’s operations throughout the Goldfields region, and now there is one more to add with the completion of its most recent project at IGO’s Nova mine.

Despite the site’s existing automation infrastructure, when it came time for upgrading, RCT Automation was selected as the preferred supplier by Barminco, a subsidiary of global mining services group Perenti.

“Technology and innovation are a key focus for Barminco, and we appreciated the simplicity of the RCT Automation solution – quicker setup times and ease of use for our operators,” Darren Kwok, Head of Mining Electrification and Technology for Perenti Contract Mining, said.

The loaders are operated from the safety and comfort of Automation Centres, which have been situated both underground and on the surface of the mine.

To enhance sustainability and cost efficiency, existing cabins were repurposed, refurbished at RCT’s Kalgoorlie branch.

Kalgoorlie Branch Manager, Rick Radcliffe, said: “The cabins required sandblasting and painting before we lined them with fridge panelling and fitted them out with RCT’s state-of-art ergonomic chair and operations centre.”

In addition to providing agnostic automation, RCT was able to work with Barminco to use both the existing underground communications technology and supplement it with the RCT connect to ensure we provide the best and most cost-effective solution for the client. The team also provided extensive operator training to empower site and ensure self-sufficiency with the technology.

Kwok added: “We have a good working relationship with RCT, and this extends beyond just the service delivery and project delivery.

“Outcomes from the project have been positive and we have worked collaboratively with RCT to ensure any operational concerns raised were reviewed and their product offering improved based on our feedback.”

Radcliffe said: “When two companies have the same goal of implementing quality products into a technology focused operation, they will always be successful, and that was certainly the case at Nova.

“We are looking forward to working with Barminco over the coming months to assess the impact that the project has had.”

RCT supplies teleremote dozing solution to multi-metal mine in Finland

RCT says it has deployed a state-of-the-art teleremote dozer at a multi-metal mine in Finland looking to further automate the mine site and improve overall employee wellbeing.

The ControlMaster® technology on the Cat D11T dozer was chosen for numerous reasons, including its durability, interoperability and high level of customer support, RCT said.

“The site experiences extreme temperatures and has legislation in place surrounding dust control,” RCT’s BDM, Mike Thomas, explained.

This legislation, while necessary for operators’ health, significantly reduces the amount of time employees work each day while operating manually from the cab of the machine.

The mine site was after a solution, and they looked to RCT for one that addressed all their requirements, the company said. Implementing RCT’s ControlMaster Teleremote technology removes the operator from the machine itself and relocates them to a safe, ergonomic working environment. In this instance, workers are relocated to a state-of-the-art automation centre within the mine operations, keeping them safe from harsh weather conditions and exposure to dust.

“The technology is extremely robust, which means it can operate effectively in extreme weather conditions such as the -50°C experienced on site,” Thomas said. “It’s fit-for-purpose, designed to cater to mining clients, all over the world.

“In addition to this, ControlMaster is extremely flexible with third-party networks and other solutions which is what makes the technology stand out from competitors.”

The technology has been well received on-site with all operators very happy with the implementation, according to RCT, with the new way of working on site fully embraced by operators.

“They are investing in their future and the way to do work to look after their employees now and in the future,” Thomas added.

RCT leverages ControlMaster remote-controlled tech on Amphiroll Mud Scroller

RCT has found a new application for its ControlMaster® remote-controlled technology package after successfully deploying the solution on an Amphiroll Mud Scroller working on tailings ponds.

Operations are now more efficient and safer for the Western Australia-based earthmoving team using this equipment, according to RCT, now owned by Epiroc.

The mud scroller, used to aerate the caustic mud of the tailings pond to dry it out, was previously a manual operation requiring two machines operating at one time for personnel safety reasons.

The ControlMaster Line-of-Sight solution has removed the operator from the cabin and allows them to control the machine from up to 200 m line of sight, according to the company. This custom one-off kit was designed, supplied and installed by both the Perth Customer Service and RCT Custom team, the company’s designated bespoke solutions department.

“This solution removes operators from any potential danger that could arise from them physically being out on a tailings pond and allows them to instead carry out the task from the safety of a light vehicle located nearby,” RCT’s Account Manager, Phill Dean, said.

The introduction of this technology has also dramatically changed how the Mud Scroller is transported to various sites, according to RCT.

“Previously amphirolls were twice the size requiring oversize movement permits and weighed about 18 t, so moving this piece of machinery required large multi-lift crane operation,” Dean said. “Now, the logistics of moving the small unit is easier and only requires a large tile tray and this in itself reduces mobilisation costs substantially.”

As well as deploying the ControlMaster technology, RCT designed, manufactured and installed the EarthTrack® custom dashboard.

“This dashboard was designed to display all the integral information in an easy-to-read format,” Dean said. “It will let the operator know the pump pressures, engine temps, fuel level and an overall live health report.”

The new and improved mud scroller remote solution was deployed at the beginning of the year in trials and is being used today with great success, according to the company.

RCT equips Northern Star’s Ramone mine with autonomous and digital tech

RCT says it has partnered with Northern Star Mining Services (NSMS) to implement a digital autonomous mining fleet at the Ramone gold mine in Western Australia.

The Ramone mine, near Wiluna, is owned by Northern Star Resources, the parent company of NSMS. It is 35 km southeast of the Jundee Gold Mine, which Northern Star also owns.

The technology has significantly advanced autonomous fleet production activities and sets the underground operation on a pathway to full mine digitisation, according to RCT, which is now owned by Epiroc.

The rollout represents the latest in a long line of successful projects that has seen RCT automate NSMS’s underground mining fleets across the Kalgoorlie and Yandal regions.

At Ramone, machine operators will use RCT’s ControlMaster® Automation Centre and supervise two Sandvik LH517i underground loaders commissioned with the latest ControlMaster digital solution.

The technology significantly enhances production by enabling faster autonomous loader cycles and greatly reduces maintenance downtime associated with machine damage, RCT said.

Once RCT’s ControlMaster Automation Centre is relocated from underground to the surface on site, it will allow for fast “hot seating” and enable site managers to capture the time previously lost over the shift changes and continue production cycles during firing activities, it added.

The NSMS team at Ramone is benefitting from the rollout of RCT Connect, the only mine site communications network designed to accommodate autonomous mobile machine fleets, according to RCT.

RCT Account Manager, Scott Phillips, said: “Our digital automation technology will provide the Ramone operation with every advantage to mine safely, efficiently and continue to make solid advancements for years to come. Northern Star Mining Services’ investment in our specialised communications technology provides a strong foundation from which to grow autonomous operations as the mine evolves and site needs change.

“Our experienced Goldfields team has worked very closely with the Ramone site team to ensure this initial rollout goes smoothly and we are very pleased with the successful outcome.

“This is just the first chapter in what we hope will be a long and very productive working relationship between RCT and the Northern Star Mining Services crew at Ramone.”

RCT’s Remote Operations Centre advances Gold Fields’ Granny Smith mining ops

Gold Fields’ Granny Smith operators are now benefitting from the availability of RCT’s Remote Operations Centre (ROC) to manage some of its mobile equipment fleet from its Perth head office, some 740 km away from site.

This major advancement will revolutionise the way they do mining by allowing operators to control or supervise semi-autonomous fleet activities in real time from the comfort and convenience of a central office location, according to RCT.

The digital ROC’s deployment represents the next major development in Gold Field’s autonomous mining operations and enables personnel to work effectively from a major city, which makes the job more accessible to a wide range of workers and reduces the company’s carbon footprint.

The project is made possible by RCT’s ControlMaster® digital automation solution, which is already used by Gold Fields to manage its underground loader fleet from the mine’s surface.

However, the digital ROC technology means Gold Fields can offer significantly more flexible working arrangements and accommodate work/life balance requirements among their workforce.

Initial testing proved the ROC can instantaneously manage multiple underground loaders at one time operating in different locations within the underground mining complex, according to RCT.

The digital ROC technology means Gold Fields’ operators will be able to access ControlMaster’s latest features as they are released, helping enhance semi-autonomous fleet operations on-site.

RCT and Gold Fields’ engineers worked together to implement the ROC and link it with the mine site through Gold Fields’ secure, dedicated network.

Granny Smith’s Mine Manager, Michael Place, said: “The Perth ROC started as a proof-of-concept trial following the digital upgrades project in December 2021. The ROC was aimed at showcasing Gold Fields Australia’s network capability and RCT’s digital operating technology but has now opened the doors to exploring future avenues in how we work at our underground operations.”

RCT Account Manager, Scott Phillips, said the ControlMaster ROC incorporates RCT’s latest digital technology which will fully empower Gold Fields to fulfil its mining fleet needs going forward.

“We are pleased to help Gold Fields take this next major step in their autonomous mining journey and implement technology that brings about major operational efficiencies,” he said.

“This project is only the beginning, and we look forward to working closely with Gold Fields to advance their mining operations in the future.”

RCT turns Gold Fields’ Granny Smith mine into ‘digitally connected powerhouse’

RCT’s latest partnership with Gold Fields in Australia has seen, it says, the transformation of the Granny Smith mine and machine fleet into a state-of-the-art, digitally connected powerhouse.

The project, which RCT says embodies the mining company’s key value of innovation, is designed to increase productivity.

Gold Fields’ Granny Smith mine is no stranger to RCT, having been one of its technology partners for more than 20 years.

This latest project has seen the Eastern Goldfields underground gold operation become one of the most innovative, digitally-connected mines in the world, according to RCT. The project saw its Kalgoorlie-based team of innovative technicians upgrade the site’s six existing Caterpillar loaders from analogue to digital.

This required the Kalgoorlie branch team to design and build specialised mounts and overhaul the site’s existing cabins. In addition, a total of 11 Area Access Controls (AAC) were also converted from analogue to digital to facilitate the upgrade.

“We recognise that they made a significant investment into the original technology, and we wanted to find the most cost-effective and sustainable solution available,” RCT’s Kalgoorlie Branch Manager, Rick Radcliffe, said.

The team converted three of the site’s existing analogue TeleCabins and transformed them into digital ControlMaster® Automation Centres for underground use and two surface Automation Centres to digital, bringing them into the future.

The site chose to use RCT’s own full-scale digital communications solution – RCT Connect – to meet the demands of autonomous machines across the mine site. The technology will cater to Granny Smith’s current and future machines, according to RCT.

The Kalgoorlie branch finished the upgrades in December last year, and although the technology has only been in place for a few months, the site has experienced amazing results from day one, according to the company.

Granny Smith Mine Manager, Michael Place, said: “The ability for the operators to mine from the surface with a pristine picture/video thanks to the digital network has meant they have been able to increase the number of buckets per shift, while adding to the comfort of the operators.

“Implementing the new digital infrastructure RCT Connect has significantly improved both the availability and reliability of Granny Smith’s semi-autonomous remote production loaders and stoping fronts to date.”

The upgrade saw the popular analogue technology that uses the Yagi antenna replaced with RCT Connect.

Radcliffe added: “While the Yagi’s have been a tried and tested technology for many years, our digital RCT Connect Access Points has taken the Control Master underground communications system to another level. The system is now more reliable and provides a clearer picture and improved operator visibility.

“The feedback we have received from site is that the operators love the new technology and they wished they implemented it ages ago.”

As well as experiencing the significant benefits of digital technology today, Granny Smith is futureproofing its operations, allowing it to make small, incremental changes as and when they are ready, RCT said.

RCT Connect, RCT says, is a plug-and-play system, making it easy to install and maintain. The technology has produced a clearer picture, which has greatly assisted Granny Smith personnel to continue operating their machines safely in high-risk locations.

Radcliffe concluded: “Another added benefit to moving to digital is that RCT can now remotely support our clients to a higher level and are able to monitor and complete repairs in a short timeframe, as it eliminates the need for a technician to travel to site to troubleshoot in many cases.”

RCT automates underground loading cycle at Victoria gold mine

Thanks to the deployment of RCT’s market-leading digital automation technology, a prominent gold mine in Victoria, Australia, has been able to achieve major productivity improvements on site, according to the technology company.

This transformation has resulted in an upgrade to the site’s mobile equipment fleet capabilities, enabling fully autonomous production loader cycles as well as providing a pathway for future operational improvements, RCT says.

RCT’s latest ControlMaster® technology empowers site personnel to control the entire fleet from Automation Centres located on the mine’s surface and allows for rapid cross-shift changes, according to the company. With RCT’s digital automation offer, machine operators can supervise seven Cat R2900 underground production loaders from the surface, which significantly improves operations.

The ControlMaster Multiple Machine Control (MMC) feature means an operator can switch between production loaders during auto tramming and supervise specific elements in the load-haul-dump cycle.

RCT Account Manager, Wayne Carrington, said the team is pleased with the outcomes of this significant package of work on site.

“The project represents the next chapter in a longstanding relationship between the companies with the gold mine having used ControlMaster across fleet operations for many years now,” he said. “Our new digital offer will set the site on a pathway to advancing their entire operations and realising strong and consistent productivity gains over the life of the mine.

“With operators now relocated to the mine’s surface, the technology is demonstrating a new standard of safety for mining personnel.”

Carrington concluded: “Our technical team have supported the site throughout this transition and we will be here to support site personnel with any future needs as well.”
