HARD-LINE, aligning with its brand-agnostic prowess, has launched Bucket Assist at CONEXPO-CON/AGG 2023 in Las Vegas, USA, an add-on feature to its TeleOp systems that gives the TeleOp operator a visual representation of the position of the boom and bucket in relation to the ground.

The company’s current and new clients can opt for this feature that, HARD-LINE says, will bring the machine operator closer to the machine without leaving their TeleOp control stations, increasing productivity while continuing to keep the machine operator at a safe distance.

Phil Pelland, Vice President, Sales, HARD-LINE, says: “Tactile feedback from the machine is crucial for any machine operator to judge the position and placement for optimum productivity. This is a solution our customers needed, and we are pleased to deliver.”

In addition to this new feature, HARD-LINE has made an announcement on a new product that, it says, will revolutionise teleoperation. The new product is a compact box that CONNECTs everything from the machine to its operator by enabling successful collaboration between HARD-LINE and its clients. This new product will continue to keep safety at the forefront while also shining the light on a core company value – collaboration – it says.

Bell Equipment on its autonomous ADT transition with xtonomy, Pronto AI

Four years after commencing extensive testing, global ADT specialist, Bell Equipment, reports that autonomous technology is now at the adoption stage with more customers in the United Kingdom, South America and Australia set to introduce autonomous Bell ADTs on their work sites during 2023.

“We’re extremely excited to have reached the adoption stage,” Bell Equipment Product Manager, Brad Castle, said. “Right now we are working closely with one of our UK customers. They are a leading mobile plant supplier and earthmoving contractor that has a large existing fleet of Bell ADTs and is looking to initially install an autonomous system onto two B30Es for a quarry application. Initially, they will be introducing autonomous ADTs on two of its sites as part of a continuous drive to improve safety.

“At the same time, we have a mining customer in Australia who will be introducing five autonomous Bell ADTs later in the year. Both these customers have chosen xtonomy as their preferred guidance system.”

Castle explains: “Providing autonomous-ready machines will be a part of our core business in the future, but in terms of sensing and guidance systems we decided that it makes more sense to partner with market leaders and innovators, as we do with drivetrain, hydraulics and electronics technologies in our trucks. Bell currently has two approved service providers, xtonomy, based in Europe, and Pronto AI in the United States, both of which can work with Bell customers from anywhere in the world.”

Xtonomy has had B30Es operating autonomously in the Alps since 2020. Pronto has established two test sites in the US, one at a Texas sand mine and another in Reno, Nevada, where three autonomously operated Bell B45Es and a Bell B50E are working in a quarry. In addition, it will soon be establishing a demo site in South America.

“As part of our strategy to enable interoperability between our ADTs and various control systems, so that customers have a choice of third-party suppliers, we have recently engaged with a third supplier and hope to begin testing this system later this year,” Castle adds.

The xtonomy and Pronto AI systems, although both autonomous, offer different benefits depending on a customer’s needs.

“Xtonomy has vast experience in the autonomous field with years of stable testing. It offers a complex radar-based system, which is less affected by inclement weather, but requires higher upfront costs and relies on the loading tool operator to manage the operation,” Castle says. However, the continuous site and object mapping, with minimal manual interaction, makes the system well-suited to multiple load and dump sites. In addition, the advanced in-cab display and supervision screens allow for easily integrated with other equipment on-site to provide a fully autonomous offering, according to Bell.

“Pronto AI, on the other hand, offers quick deployment with a much simpler, integrated system that has subscription-based pricing with minimal upfront costs,” Castle says. “Theirs is a camera system and the non-dynamic site and object detection require manual interactions. However, it is controlled by a user-friendly mobile app and routes can be easily changed by manually driving them. It is also possible to run this system over a private LTE network.”

He concluded: “The beauty of both systems is the flexibility they offer our customers. Bell provides a standard cab with no extra hardware taking up space to create an environment where manual, remote or autonomous operation is interchangeable. This means that once an ADT has finished a contract on an autonomous site, the sensory and control system can easily be removed and the truck either fitted with a new system for another site or be used in a manual operation.”

Exyn and Easy Aerial join forces on new ExynAero EA6 flagship airframe

Exyn Technologies has announced it will be partnering with Easy Aerial to launch its new flagship airframe, the ExynAero™ EA6, integrated with ExynAI™ and optimised for Exyn’s diverse use cases.

Exyn has been using the DJI M210 as its main airframe for mining and commercial customers. However, with the M210 product transitioning to end of life, Exyn needed to source its new flagship airframe.

This airframe needed to continue to meet its commercial customer demands, and be US-made to comply with US Government customer requirements. Beyond sourcing a new airframe manufacturer, Exyn was searching for a new partner with a product that would be capable of evolving with the company, it said.

After an extensive evaluation of different airframe manufacturers, Easy Aerial was selected as the preferred partner. By stepping into a new, customised platform Exyn has greater flexibility on future adaptations of the product based on customer feedback, it said. Exyn also benefits from the option to expand its offerings to include Easy Aerial’s drone-in-a-box solution, automated charging and remote operations to further automate its autonomous robot.

Exyn said: “Easy Aerial and Exyn, both agile and dynamic startups, were able to quickly and nimbly adjust to customer feature requests, supply chain constraints, new sensors and specialised configurations. In addition, Easy Aerial and Exyn are ISO-9001 certified and Easy Aerial is AS9100 certified, which will help facilitate quality production of the ExynAero EA6.”

Nader Elm, CEO of Exyn Technologies, said: “We sought out to find a product partner that shared our mission and would be an active collaborator in building an ExynAI-specific robot to be used across the industry verticals we address. In our search, we found a compatible airframe in the Easy Aerial Osprey and an incredible team behind it that would jointly propel us forward.”

The Osprey platform is beneficial to Exyn in its business verticals like mining and construction. The Osprey is a hexarotor airframe that provides motor redundancy in case of failure. The platform offers longer airborne endurance, while maintaining a slightly smaller form factor than the M210 and accommodates increased thrust capabilities.

Ido Gur, CEO of Easy Aerial, added: “Exyn and Easy Aerial share a common vision of automating monitoring solutions. Many of our customers share the same operational needs of autonomous drone-based robotics to operate in the most demanding environments, so this partnership was a no-brainer. We’re ecstatic to be working alongside Exyn, supporting our enterprise and government customer base.”

The Komatsu AZPG: bringing unique mining concepts to life

Automation, Environmental, Equipment maintenance, IoT, Mining equipment, Mining services, Mining software, Power supply for mines, Sustainable mining, , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , ,

Seeing Komatsu’s Arizona Proving Grounds (AZPG) in person, it is easy to understand why the OEM is in a leading position when it comes to both surface mining automation and electrification.

The 660-acre (270-ha) facility is a living and breathing example of mining’s past, present and future; touring round, one can see 20-plus-year-old machines, the latest -5 ultra-class haul trucks and concept vehicles that will form the basis for future commercial autonomous and/or electric solutions.

These concept vehicles – at least when IM visited in November – included the company’s EVX battery proof of concept vehicle and the cabless IAHV autonomous mining truck concept.

The EVX is based off the basic 860E platform (a 254-t payload machine) and was shown off at MINExpo 2021. Prior to that, it had been testing out its all-battery power functionality at AZPG.

The IAHV, which debuted at MINExpo 2016, was developed by Komatsu as an unstaffed vehicle designed to maximise the advantages of such operation. It remains on show, with the company incorporating several learnings from this vehicle into its standard Electric Drive Trucks (EDT) and autonomous products.

Pat Singleton, Product Director, EDT, refers to AZPG as the “ultimate laboratory to be able to bring unique mining concepts to life”.

He added: “The testing we do at AZPG gives us the opportunity to reduce product development risk and take the validation process one step further before the products make it to the mine.”

The original focus at AZPG was the EDT product line, yet, as Komatsu has expanded its product offerings, more solutions continue to be tested or validated at the facility each year.

This testing is extensive, as was made obvious to IM while navigating an autonomous vehicle ‘assault course’ and hearing about new wet- and dry-disc brake trial combinations, higher speed tramming on autonomous haul trucks and more.

It is not just trucks subject to these try outs either, with hydraulic shovels, surface drill rigs, water trucks, dozers and other vehicles having a presence on site.

“If anything, the importance of AZPG has increased as technology has continued to evolve,” Singleton said. “AZPG allows for a single location to harmonise development efforts of all the Komatsu entities, providing research and development into our products.”

What’s more, the facility is located in Arizona’s renowned copper heartland.

This has been very useful for Komatsu, with Asarco’s Mission mine next door to the facility representing a real life mine site testing opportunity for solutions that have graduated from AZPG.

AZPG has 23 full-time staff, but its desk count is much higher, indicating the number of visitors and partners AZPG welcomes on a weekly basis from across the globe.

Some of these visitors include FrontRunner® autonomous haulage system (AHS) customers, who have, more recently, been invited to send operators to the facility for invaluable training ahead of planned autonomous deployments.

Anthony Cook, Vice President, Autonomous Systems, Mining Technology Solutions, told IM that this approach is enabling mining operations to leverage more of the benefits of AHS from day one of deployment, reducing the need to conduct a ‘soft start’ with the technology as operators come to terms with the transition from staffed to autonomous operations.

A representative from Komatsu’s dealer network was receiving training on the AHS system during IM’s visit, with Cook confirming another major mining customer and Komatsu distributors had sent operators to Arizona earlier in 2022 ahead of a planned deployment in 2023.

AHS developments are a key focus area for AZPG, with the on-site trucks testing out many different scenarios that customers could experience at their operations.

Software updates make up many of the ongoing FrontRunner AHS developments, but the company also continues to explore the use of more sensors and cameras on board its vehicles for obstacle detection and positioning. This is all geared towards improving visualisation, communication and safety, reducing potential false positives during operation and ultimately helping to improve productivity.

As for software upgrades to FrontRunner AHS, all developments are initially tested in a bench environment where the company can simulate the system. This may be within the former Modular Mining facility, also in Tucson, or at another one of Komatsu’s many testing hubs.

“Once it has passed virtual testing then final functional and stability testing is validated at AZPG before release to the customer,” Singleton said.

Some recent testing related to mixed fleet operations of staffed and autonomous trucks that originated in the lab to later emerge at AZPG has since led to a FrontRunner first at Anglo American’s Los Bronces mine in Chile.

The mining company only recently started its AHS deployment at the copper mine, initially going live with ten 930E-5 trucks, but Cook confirmed to IM that these vehicles are now interacting with staffed trucks in the mining environment.

“We’ve got off to a very strong start at Los Bronces, with Anglo American really embracing the technology and pushing it to its limits,” he said.

The full Los Bronces deployment could see 62 electric drive Komatsu 930E trucks running by 2024.

Those who visited MINExpo 2021 in Las Vegas will also remember the PC7000-11 shovel that was being teleremote operated live from the show, while the unit was over 600 km away at AZPG. This unit (above) is still positioned on site and the teleremote operation is continuing to be refined from inside the facility, with AutoSwing and AutoDump functions a few recent notable additions for improved operability.

Komatsu expects to replace this shovel with a backhoe version later this year, to also be teleremotely operated.

Trolley transformation

The first vehicle IM saw when driving up to AZPG was the EVX; its shiny yellow exterior providing the perfect contrast to the rich blue backdrop of the Tucson sky.

Since leaving Las Vegas in September 2021 and heading for Tucson, the company has made preparations to remove the small on-board battery which was displayed on the Komatsu stand and begin replacing it with a larger one from one of its integration partners.

The connectors for trolley were still on board and the team was awaiting final commissioning of the on-site trolley line ahead of further testing.

Singleton explained: “The EVX was a proof of concept to demonstrate that a large electric drive haul truck could be powered by a battery. Now that we better understand the ability of this technology to work in our EDT products, we must continue to advance the technology to drive increased performance and reduced operating costs.”

To date, Komatsu has continued with truck testing to learn how the various subsystems work with batteries while finalising its battery chemistry.

“We’ve also installed trolley infrastructure, which will allow us to conduct further testing on batteries and other alternative power sources,” Singleton said.

This infrastructure – made up of 39 poles that are ‘movable’ and ‘self-supporting’ – could support two 980E-5s running on the line at the same time.

Initially, it will support both the EVX and one 930E running in tandem.

The line itself is powered by a 9 MW substation, which Siemens and a local electrical and engineering company established.

The trolley course has been designed with a 60° corner to demonstrate to operators that this technology is for more than just straight hauls.

“This highlights the flexibility of the system and shows mining operators where the technology can already go today,” Cook said. “The concrete pillars, which can be moved with wheel loaders and other support equipment, are an indication that the trolley can ‘move with the mining’, too.”

Singleton said the next development for the EVX will focus on an increase in the battery capability and the investigation of proof of concept on a variety of static and dynamic charging options.

The trolley line will, no doubt, play a role in this testing, although it is not yet known if a single or hybrid power setup will be selected initially.

What is more certain, however, is the status of fuel cell electric vehicle (FCEV) testing on the EVX. Singleton said research into this area continues, yet a practical test where fuel cells and a battery were mounted on the chassis was some way off.

At this early stage, Singleton says the first commercial power-agnostic offering the company establishes will likely be diesel and/or diesel trolley.

He explained: “This approach delivers reduced risk to the overall portfolio by blending the power-agnostic chassis with a refined version of an existing technology (diesel engine + overhead dynamic trolley).”

“It also serves the secondary purpose of allowing battery technology the opportunity to mature from a performance perspective as we work to define overall truck fleet performance. Additionally, static and dynamic charging options (including development of an industry-standard connector) are within the scope of this product.”

And the first commercial power-agnostic truck will be in the 291 t (320 ton) class – the same size as a 930E – Singleton confirmed, adding that scalability was something being considered at every stage of the truck’s development.

“Scalability is the overall goal and is in alignment with the general power-agnostic approach to our design,” he said. “The major challenge will be the scalability of the energy storage componentry from a cost and performance standpoint. This is the primary driver behind the continued deliberate development cadence designed to give the battery technology time to mature over the intervening period before the design is finalised.”

When asked about fixed fast charging – a concept that has risen up the mine truck charging rankings of late with Charge On Innovation Challenge work from Hitachi Energy and a consortium led by Shell, respectively – Singleton referred to developments as a “two-way street” and a “work in progress”.

“Essentially those solutions need better definition and ‘mining proofing’ before we introduce them into AZPG,” he said. “Perhaps an opportunity exists to co-develop these technologies and improve speed to market but, again, this is still being defined.”

The trolley infrastructure at AZPG – made up of 39 poles that are ‘movable’ and ‘self-supporting’ – could support two 980E-5s running on the line at the same time, according to Komatsu

All this work sounds encouraging for those companies interested in adding to their ultra-size class truck fleets in the 2030s in line with industry-wide decarbonisation plans, but Komatsu customers looking to buy trucks today will be after future-proofed solutions.

Komatsu is all too aware of this and planning to provide a battery retrofit solution for its current -5 products, Singleton said.

GHG Alliance and beyond

As has been well documented, Komatsu has aligned with a core group of customers under its GHG Alliance to accelerate developments on the electric haulage front.

Rio Tinto, BHP, Codelco, Boliden, Teck, Antofagasta Minerals SA and Freeport-McMoRan are key stakeholders within the alliance and will be keen to see what testing emerges on that trolley line into 2023.

While Singleton said the communication process with these customers was still being refined, he acknowledged AZPG’s role in future developments.

“There is no question AZPG will provide a critical backdrop to accelerating our efforts and streamlining our ability to communicate and advance the development progress with our customers,” he said.

Whether the company chooses to initiate an early-learner program like the other big yellow equipment maker it competes with is yet to be seen, with Singleton saying its plans will leverage the “Komatsu approach” regardless of what the competition is doing.

What is clear is that AZPG will continue to keep Komatsu on the leading edge of mobile mining equipment technology developments.

As evidence, Cook reeled off several ongoing projects the company was engaged in, including an autonomous water truck in Australia, automated dozers in Brazil and plans to semi-automate electric blasthole drills.

Going forward, another consideration will be the ability to integrate AHS with trolley operations.

“Komatsu, as an organisation, is committed to solving our customer’s and the industry’s challenges, and we will continue to leverage AZPG and the wider Komatsu network to do this,” Cook said.

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.”

Navtech Radar out to reduce ‘single point of failure’ issue in mine automation

Automation, Communications in mining, IoT, Mining equipment, Mining events, Mining safety, Mining services, Mining software, , , , , , , , ,

Relying solely on one sensor-based technology for autonomous operation of vehicles is a risk most mining operators cannot afford to take, according to Navtech Radar’s Sam Wood.

This threat to operational continuity is likely to become wholly apparent in 2026 when an expected solar excitation event pushes many GPS-based systems offline, Wood says.

The Product Manager for Oxford-based Navtech Radar was speaking to IM on the sidelines of the recent Bauma 2022 fair in Munich, Germany; an event where the company launched its Terran360 single sensor radar localisation solution.

Terran360 leverages Navtech’s millimetre wave radar technology to, it says, reliably position a vehicle in its surroundings, particularly in harsh working environments such as mining and construction.

While Navtech is very much tied to radar-based solutions, it is focused on integrating its platform into multi-sensor fusion setups at mine sites, integrating with LiDAR, GPS and others.

“We see our solutions complementing and integrating with other technologies,” he said. “We feel mines and other industrial sites should not have a ‘single point of failure’ within an automated setup as this can lead to unnecessary downtime, or – in some cases – potential accidents or injuries.”

Autonomous vehicles in the mining and construction sectors typically rely on GPS sensors to report their location, but the ability to reliably maintain centimetre-level positioning required for autonomy, especially within developments with tall infrastructure, deep pits or at high latitudes, is often compromised, Navtech says.

“Terran360, on the other hand, draws on high resolution radar technology which penetrates the atmospheric and weather conditions to constantly deliver highly accurate, centimetre-level location data,” it explained.

Wood says increases in GPS attacks – through “jamming” and “spoofing” – means relying on GPS alone is becoming commercially risky for autonomous mine operators. This is on top of the solar excitation event expected in 2026.

“Terran360, and other examples of innovation developed by Navtech, aims to address these challenges,” he said.

Delivered in partnership with autonomous vehicle software specialist, Oxbotica, Terran360 is certified to IP66 standard, meaning the radar localisation technology is completely protected from water and debris, ensuring constant operation and minimal maintenance to enable 100% visibility of assets at all times, it says.

“Oxbotica’s world-class localisation algorithms are combined with Navtech’s ruggedised industrial radar sensors to provide a package that is resilient to weather and harsh environments,” Navtech added.

Oxbotica’s product portfolio for the mining sector includes software that spans the entire technological spectrum, from low-level sensor managers, through calibration, four-modal localisation (vision, laser radar and GNSS), mapping, perception (with vision, lidar or radar), 3D mapping and planning and control.

Navtech and Oxbotica have been partnering on solutions in mining, following several successful radar deployments. These include trials in one of Boliden’s major underground mines in Europe where the radar sensors are providing situational awareness to support equipment retrieval from smoke-logged mining tunnels.

Boliden is – independently from Navtech or Oxbotica – developing automation technologies for mines with the goal of maintaining round-the-clock operations, following the demonstrable improvements in safety shown using radar technology and various other sensors.

Further to this, Navtech has also partnered with Örebro University in Sweden where its radar-based sensor was trialled as part of a sensor fusion project within the university’s Centre for Applied Autonomous Sensor Systems. This has seen Navtech’s radar tested in both a teleremote and automated setup in applications such as mining.

Wood says more companies are interested in these types of automated solutions, but the company is also continuing to see demand for radar-based platforms in other mining applications.

Here he highlighted one example in Minas Gerais, Brazil, where the company’s CIR sensor-based solution is providing 3D stockpile management and anti-collision detection in a ship loader application at a port (pictured above).

Exyn’s drone-based mining autonomy ambitions taking flight

Automation, Communications in mining, Explosives and blasting, IoT, Mine surveying, Mining equipment, Mining services, Mining software, , , , , , , , , , , , , , , , , , , , , , ,

Having already achieved the highest documented level of aerial autonomy – level 4A – with its drone-based solutions, Exyn Technologies is striving for further industry firsts, Raffi Jabrayan, VP of Business Development and Commercial Sales, says.

One of its more recent breakthroughs came in Germany at the K+S’ Werra mine site, where a team demonstrated the use of the ExynAero™ and ExynPak™ at an underground salt mine.

Over the course of three days underground, Exyn’s field engineers successfully flew multiple autonomous missions in hard-to-reach areas while capturing rich, high-fidelity point clouds in a fraction of the time it would take traditional cavity monitoring systems, according to the company.

Jabrayan explained: “Several drone companies had previously attempted an autonomous mission to scan the immense cavities this specific site has, but the dust interference meant most of these missions ended within seconds.

“We were able to fly in some cavities completely beyond visual line of sight, mapping areas in a fraction of the time the teams would normally take for such manual inspections. In all, we were able to carry out a six-minute autonomous flight at the site.”

While the company did not carry out any specific modifications to its ExynAero platform to conduct such a flight, Jabrayan acknowledged that ongoing design and software improvements over the last year had enabled the company to accurately detect both dust and thin wires underground.

In addition to this, the company also displayed the capabilities of its handheld ExynPak solutions while on site in Germany.

The ExynPak, according to Exyn, can provide the world’s first real-time colourised point cloud visualisation on a handheld LIDAR scanner, capturing precise, colourised 3D models 20-30 times faster than a traditional stationery tripod or terrestrial scanner.

Powered by ExynAI™, the ExynPak ‘drapes’ real-time RGB information captured through two hemispherical fixed cameras onto point clouds created by a gimballed Velodyne LIDAR Puck LITE, providing operators a complete colourised 360° view of their environment, Exyn says.

At the Werra mine site, the Exyn team was able to capture a colourised cloud where the stratification of the rock could be clearly seen in the scan, enabling the K+S team to obtain data it would likely never be able to replicate in any other way, according to the company.

Jabrayan says such information could see operators plan their mining processes around the colourised captures, following mineralisation identified by the scans to ensure no economic ore had been missed after mucking out.

At the Werra mine site, Exyn’s field engineers successfully flew multiple autonomous missions in hard-to-reach areas while capturing rich, high-fidelity point clouds in a fraction of the time it would take traditional cavity monitoring systems

 

The ExynPak is likely to become a core part of Exyn’s next aerial autonomy offering for open-pit mining, powered by ExynAI, which enables safe flight in the most dangerous industrial environments.

“We have done some work in terms of moving our flights to the surface,” Jabrayan said. “It could cover various aspects – tailings monitoring, highwall scans…there are lots of requirements for it. We are actively working on integrating GPS into our ExynAI stack for outdoor autonomous flights, however, it’s not ready to be pushed to customers just yet.”

The company is currently working on surveys of ground-based resources, such as stockpiles, using a handheld ExynPak, plus carrying out aerial flights in manual mode.

Reaching the level of autonomy it has underground will most likely involve the help of its collaboration partner, EY, and a third company providing “software and visualisation input”, Jabrayan says, adding that he expects to see this autonomous solution come to light in 2023.

Earlier this year, Exyn, in partnership with Maestro Digital Mine, presented an aerial drone fitted with a Maestro gas monitoring Industrial Internet of Things (IIoT) device.

This new gas monitoring drone, which integrates critical gas sensors onto the ExynAero and ExynPak platforms, is effectively the “quickest and safest mobile gas monitor on the planet”, Michael Gribbons, CEO and Co-founder for Maestro, said.

Powered by ExynAI’s multi-sensor fusion capabilities, gas sensor readings are captured while the robot is in flight and displayed in real time via a ruggedised tablet, Exyn explained. These sensor readings are saved with precise coordinates in a high-fidelity point cloud that can be exported and examined in a variety of mining software.

Jabrayan says a lot of mines have reached out to the companies since first presenting the solution at the SME MineXchange Annual Conference & Expo in Salt Lake City, earlier this year.

“They are interested in the benefits such a solution could provide in terms of safety and productivity,” he said. “By flying the gas sensing drone underground soon after a blast, it could take the necessary readings and issue a notice to another system that it is safe to re-enter the area.”

This could see more mines shift away from re-entry processes based on out-of-date manual gas readings, to a system that is much more accurate and shaves – potentially – hours off operational downtime.

Exyn is closing in on a long-term trial agreement with at least one miner in Australia looking to test out this gas-sensing drone solution, according to Jabrayan.

“The long-term plan is to develop a drone-in-a-box solution that can reside underground and be flown immediately after a blast to offer the quickest possible readings,” he said. “Remote autonomous mapping of this type could see Exyn provide data to shift operators as they are heading underground, allowing them to get a picture of the environment ahead of reaching the location.”

The incorporation of such data into mine site operational processes could see drone-based solutions become vital to the running of mines in the future, and Exyn, through its post-processing pipeline, ExSLAM, is looking to enable this.

ExSLAM extracts the raw cloud from robot logs and refines it for third-party software, using a factor graph optimisation algorithm to create low-drift point cloud maps.

Jabrayan says the company continually receives plaudits from customers about the ease of use of this solution, explaining that Exyn is one of the few companies that georeferences its maps inside an existing coordinate frame.

“From there, we are able to detect all the survey points, download them, georeference them and push the data to any end-user software,” he said.

Exyn, Jabrayan says, is software agnostic when it comes to this process, but he did admit the company was in advanced talks with some leading mining software companies that could see its mapping data integrated directly into their platforms.

“We are also working with certain companies to use robotic process automation to make it a one-button process to scan, go directly into the end-user software, and create a mesh that can be used,” he said.

“We remain focused on using our technology and R&D to provide the best solution to customers in order for them to be as productive as possible and, of course, work in a more efficient and safe manner.”

Sandvik and FLANDERS to develop ARDVARC-iSeries drill rig digital interface

Automation, Explosives and blasting, IoT, Mining equipment, Mining services, Mining software, , , , , , , ,

Sandvik Mining and Rock Solutions and FLANDERS have agreed to develop a Digital Interface between FLANDERS’ ARDVARC® Autonomous Drill System (ADS) and Sandvik iSeries rotary blasthole drills.

The development of this digital interface is a direct response to growing customer demand for agnostic automation systems in surface mining, the pair say.

The digital interface will enable the operation of Sandvik rotary drills via the ARDVARC ADS system with no modification to the drill rig, effectively a plug-and-play solution that allows for easy deployment of Sandvik drills to mine sites, FLANDERS explained. This open-architecture approach simplifies the installation and commissioning process while ensuring the customer retains OEM warranty and aftermarket support.

This agnostic approach to delivering digital solutions allows customers to select the value-added solutions that best meet their needs, whether that be the drill or the operating system powering the drill, FLANDERS added.

ARDVARC improves drill productivity by up to 30% and provides a significantly safer working environment for workers operating in complex or hazardous conditions, according to FLANDERS.

With its autonomous operating technology, FLANDERS helps its customers pro-actively optimise drilling and increase plant availability. The introduction of autonomous technology at the mine adds significant environmental gains for diesel machines, reducing fuel consumption and CO2 by up to 7.3% compared with a manned operation.

With its autonomous operating technology, FLANDERS helps its customers proactively optimise drilling, improve fragmentation, improve loading and hauling productivity and increase plant throughput.

The first deployment of the FLANDERS/Sandvik Digital Interface is scheduled for the December quarter of 2022 with further deployments being scheduled soon after that.

Sandvik in its statement says it “will continue to develop and support AutoMine® Surface Drilling solutions for remote and autonomous operation of the full range of Sandvik iSeries drills”.

FLANDERS added that it has signed a deal with Anglo American to incorporate ARDVARC on all new and existing drills at Anglo’s Mogalakwena mine in South Africa, including the recently purchased Sandvik DR410i blasthole drills.

The third (of four) brand new Sandvik 410i drill is currently being converted to an ARDVARC Autonomous system at the state-of-the-art facility in Middelburg, South Africa.

FLANDERS has already deployed ARDVARC Autonomous drills to Mogalakwena, converting Epiroc Pit Viper 271 XC drills.

Sandvik Mining and Rock Solutions has received a large order in Chile for surface mining equipment and its AutoMine® Surface Drilling solution from Movitec, a contractor on Codelco’s Rajo Inca open-pit project.

The order includes two Leopard™ DI650i down-the-hole (DTH) drill rigs and two Sandvik DR412i rotary blasthole drill rigs, including AutoMine® Surface Drilling systems for fully autonomous operations.

AutoMine Surface Drilling is an autonomous solution for a wide range of Sandvik iSeries surface drill rigs, designed to improve safety, reduce costs and increase productivity. It enables an operator to control multiple rigs remotely from a comfortable location in line-of-sight or a distant control room – improving working conditions and safety, Sandvik says.

Sandvik iSeries drill rigs are equipped with iDrill technology, a scalable automation platform that provides automation options and digital services designed to speed up the production process and support mining operations. Performance and navigation iDrill technologies work together to produce accurately placed, consistently clean and precision-drilled holes – delivering improved fragmentation, downstream throughput and asset utilisation.

“We are pleased to work with Movitec and Codelco on this project,” Emilio Vega, Business Line Manager for Automation, Sales Area Andean and South Cone at Sandvik Mining and Rock Solutions, said. “The AutoMine Surface Drilling solution will enable the customer to use the drill rigs to their full potential and boost productivity with capabilities for fully autonomous operations.”

The new order also includes one Sandvik D75KX rotary blasthole drill rig with added intelligence and improved operator ergonomics. Delivery will take place in two phases before year-end 2022, with fully autonomous operations ramping up in 2023.

“We thank Movitec for their well-placed confidence in the Sandvik brand and technology,” Patricio Apablaza, Vice President Sales Area Andean and South Cone at Sandvik Mining and Rock Solutions, said. “We look forward to supporting them in increasing the safety, productivity, profitability and quality of their operations.”

In addition, Sandvik Mining and Rock Solutions will also provide contractor Movitec with remote operation training and six months’ on-site service to ramp up support as they transition to autonomous operations.

David Hallett, Vice President Automation at Sandvik Mining and Rock Solutions’ Digital Mining Technologies Division, said: “We are excited to partner together with Movitec on their journey to adopt AutoMine Surface Drilling at Codelco’s Rajo Inca open-pit project. This project will play a significant role in establishing Sandvik’s position as a leading technology partner for autonomous surface mining within the Chilean and South American market.”

Codelco officially began the works of Rajo Inca last year, moving from underground mining to open-pit mining.

Hitachi Rail says it and Rio Tinto have marked another significant AutoHaul™ milestone with the commissioning of the autonomous rail transport system for the new Gudai-Darri iron ore mine in Western Australia’s Pilbara region.

The greenfield mine development has involved the construction of a 166-km rail spur to connect the new mine to Rio Tinto’s existing AutoHaul rail network in the region.

The world’s first fully automated heavy-haul, long-distance rail system, AutoHaul enables 220 trains, which are monitored remotely from an operations centre in Perth, to travel safely and efficiently across more than 1,866 km of track from mines to ports – without the need for onboard drivers, Rio says.

Hitachi Rail, as the technical lead behind AutoHaul’s development, has provided the systems and software to connect the new section of rail for Gudai-Darri. This has included onboard and control centre technology, trackside equipment, radio base stations and automatic train operation interface software for locomotive control, level crossing safety and location tracking, Hitachi Rail said.

All systems and software are now operational following the first production test run and subsequent successful system commissioning .

Hitachi Rail Australia Senior Director, Roslyn Stuart, said: “The Gudai-Darri AutoHaul network expansion project is a natural extension of Hitachi Rail’s long-term collaboration to deliver innovative rail transport solutions for Rio Tinto. The project has seen Hitachi Rail and the Rio Tinto AutoHaul team deliver another ‘first’, with back-to-back loading (high performing automated train loading) to be introduced on the Gudai-Darri mine rail loop.”

The Gudai-Darri mine will also deploy autonomous haul trucks, fully autonomous water trucks and autonomous training solutions, and will be partially powered by a 34 MW photovoltaic solar farm solar plant.
