Testing: the secret sauce of Sandvik R&D

Jani Vilenius has his plate full at Sandvik Mining and Rock Solutions. As Director of Research and Technology Development, he is brought into most conversations the business area has about future mining products.

In fact, he even works across the Sandvik Rock Processing business area on occasion, as well as overseeing the design centre in Bangalore, India, which provides “value engineering” across Sandvik Mining and Rock Solutions divisions.

“We coordinate research programs and projects, not products,” Vilenius told IM recently in the company’s newest office in Tampere, Finland. “This may be overseeing the concept machines that we have been producing for several years, as well as technology partnerships with universities.

“We aim to think long term within the Research and Technology Development and Services team, but not too long term as the world is much more agile nowadays than it used to be.”

This means Vilenius’ team has to coordinate all of the activities taking place at the Test Mine in Tampere, provide a ‘steer’ on engineering services and safety processes needed to satisfy today’s and tomorrow’s requirements and regulations, drive cybersecurity and sustainability developments across Sandvik Mining and Rock Solutions in the R&D phase, plus integrate the thinking between the rapidly-expanding Digital Mining Technologies division within Sandvik Mining and Rock Solutions and the R&D team.

And, as of a month ago, his team also coordinates testing at the new Surface Test Pit: a new surface mining test bed being developed 40 km northwest of the underground test mine.

This is all underwritten by the strategic priorities across the business area he primarily works in, as well as the Sandvik group goal of ensuring 25% of revenue comes from products that are less than five-years-old.

To tackle these tasks, he has a sandbox (soon to be two) that all equipment providers would like to have.

The Test Mine in Tampere comes with 6 km of tunnels at a depth of 40 m, with potential to expand further. Positioned beside a glass factory and close to the company’s rock drills factory, this test mine offers the company and its customers everything they need to make strategic business decisions in an environment that can, for instance, replicate the heat and humidity of a deep underground mine in South Africa, as well as the biggest and widest mine galleries the industry has on offer.

This facility – which has everything your typical underground mine has except a daily throughput target – allows the company to run all its underground drills through a rigorous testing procedure prior to customer dispatch. It also allows the various divisions under the business area a chance to test out prototypes, applications and products from time to time.

For the concept machines Sandvik is becoming renowned for, the test mine acts as a place to validate conceptual thinking in a real-life environment, helping engage customers in detailed discussions as to what on-board and off-board technology elements would provide the greatest value to their operations in the near-, medium- and long-term.

The aim is to replicate this process on surface with the Surface Test Pit, providing the catalyst the company needs to reach its ambitious surface drilling market goals over the next several years.

IM sat down with Vilenius to find out how he coordinates all this R&D work, and how day-to-day testing works from a practical perspective.

IM: I imagine your department is inundated with requests from various business lines when it comes to testing. How do you go about prioritising these requests and turning them into an easy-to-follow roadmap that can lead to commercial solutions?

JV: I’ll answer that by taking a step back.

We have a technology focus built on supporting both Sandvik Mining and Rock Solutions and Sandvik group strategy. We then have roadmap items where we try to leverage technologies across many applications. These technology platforms are not always 100% suitable for both surface and underground mining, but there are elements that have similarities. For example, our latest electric concept surface rig uses the same thinking and philosophy used on other concept machines for underground. Of course, there are new elements included, but the platform thinking remains in place.

Based on this, we have different forums and conversations with the divisions and the R&D heads, discussing together where we need to put the focus in terms of testing. There are, of course, differences in sizes of the division with those who invest a bit more in R&D entitled to more access, but we also have to remain strategic about how to capture the market attention within Sandvik Mining and Rock Solutions; knowing when and what to launch, as well as what developments will allow us to achieve the required technology momentum to support both our own internal goals and the goals set by our customers.

With all these technology developments – projects, concept machines, theoretical testing – there needs to be a value proposition. For the concept machines, for instance, there is value from a marketing perspective to showcase Sandvik as a technology leader, but there is also the value of engaging with customers in conversations that, through the actual machine development, allow them to comprehend what the technology may mean for them on a practical operational level.

This rapid agility – which I would say is unique to Sandvik – means we can receive valuable customer feedback on these concept machines before we commercialise certain elements. It allows us to effectively manage risk in a market calling out for technology breakthroughs to solve complex challenges.

IM: How many tests/trials can you have going on at the same time at the Test Mine?

JV: It varies. All underground drill products are tested there before they go out to customers, which puts a lot of load on the facility, while ensuring that when customers get these units, they have been run in an environment similar to a real-life mining operation.

Then we have new prototypes not under my remit that are tested ahead of becoming ‘products’, for example in underground drilling. Then, we have several technologies we test on a daily basis with different types of test benches and subsystems.

The reality is that we would not be as agile as we are without this test mine. It is not easy to go to a customer site and get permission to test equipment as it can negatively impact their (the customer’s) production. The ability to test at our own facility gives us a layer of comfort and confidence ahead of getting to the customer site.

We cannot try or test every application in our test mine, but those scenarios we do test provide real value.

IM: Are there plans to expand the test mine further?

JV: We have a roadmap for our test mine, but this is determined with a cost versus value equation. We don’t want to have empty tunnels without testing going on regularly.

We have all the opportunities to have a third, fourth and fifth level at the Test Mine. We have, for example, recently expanded into a new area to support our underground drill products to allow testing for that. This is a function of the offering getting wider and the need to expand the tunnels to make sure the new products receive the same testing opportunities as the existing ones.

We have expansion plans focused on automation and electrification too.

IM: Speaking of automation, is fully automated (without any personnel involved) battery swapping one of the ongoing projects you are working on?

JV: I can say we have some ideas on this. It is a topic that needs addressing and discussing as automation is coming on all our equipment and all processes in the future.

Fully automated battery swapping testing is, of course, part of the roadmap.

IM: I also understand that your team originally came up with the MineGame tool for modelling battery-electric equipment fleets and infrastructure. What was this designed for?

JV: Yes, this is a tool we needed to develop to support fleet-wide electrification. It is not designed to recommend the type of machine you will get; it is more about how you implement the many electric machines in the mine, what impact this has on infrastructure, how many tonnes we can get out of different fleets, etc.

This modelling tool gives comfort to customers about the value proposition of fleet-wide electrification, while also showcasing how new, developing technologies can be implemented in greenfield and brownfield mines.

This tool – on top of those from Deswik and Polymathian within the Digital Mining Technologies division – will be a game changer for us.

IM: What about the interaction of manual and autonomous equipment? Is this something you are already testing at the Test Mine?

JV: This is an ongoing requirement from customers, who look to always alleviate production stoppages.

It is not an easy challenge to address though. Everyone knows we want to get safe systems in place with a mixed fleet as not all machines are currently automated.

There is obviously a value case for this, and the Test Mine is a good place to test it out.

All I can conclude with is to say we have many tests going on in the Test Mine…

IM: A cheeky question, I know…What will be the next concept vehicle? You’ve set yourself a big challenge with bringing one of these out every year. How are you keeping up with this?

JV: We have smaller concepts, and we have bigger concepts on the table. We need to ensure we develop the technology to get those concepts done in a timely manner and in a way that, as I keep saying, provides value.

Maybe the next one coming out will be one of those smaller concepts.

Then, of course, we have wild ideas for underground equipment further down the line.

IM: The Digital Mining Technologies division is becoming a much bigger part of SMR. Do you see a point where you will start using the day-to-day data coming off sensors on your machines to revamp existing machine designs and come up with new machines?

JV: Yes, this is mandatory for us to do at some point in time. Integrating data from the field and systems into the engineering process is a tried and tested policy in many industries – some of which Sandvik are serving – so we need to do that more in mining.

The big step I foresee on this front is when we truly understand the value of using artificial intelligence in mining. Leveraging these tools will ensure there is a continual optimisation loop that goes throughout our software, hardware and services.

LKAB bolsters automated, electric Sandvik loading fleet at Kiruna iron ore mine

LKAB has ordered 12 Toro™ LH625iE cable-electric loaders and five Toro™ LH621i loaders, all equipped with Sandvik’s AutoMine® solution, for its Kiruna iron ore mine in northern Sweden.

The order will more than double Kiruna’s electric Toro LH625iE fleet to 20, all of which will now be automated, and its total Sandvik loader fleet to 28 by the end of 2025, the OEM said.

The orders were booked in the June and December quarters of 2023, with deliveries scheduled from January 2024 through the end of 2025. The investment follows a study by Sandvik’s Trans4Mine team and calculations by Polymathian that identified opportunities for Kiruna to increase production by as much as 15% through automation of its large electric loader fleet.

“Sandvik and LKAB have a shared goal to boost production at the Kiruna mine,” Magnus Backe, General Manager LKAB Kiruna, said. “This is a true partnership to increase tonnage and improve safety through automation.”

Developed in 2020 as a collaboration between LKAB and Sandvik to replace Kiruna’s ageing fleet of 17 Sandvik LH625E loaders, the 25-t-payload Toro LH625iE is a revamped version of the industry’s largest-capacity underground loader.

“This investment supports our strategy towards a more electrified, autonomous and safer mine,” Joel Kangas, Mine Manager at LKAB, said. “We need to excavate an enormous volume of rock from depths of up to 1,300 m, and we will mine even deeper in the future. These depths present a prohibitive ventilation challenge for conventional equipment of the size we need to meet production demands. We worked closely on a daily basis with the Sandvik experts on site to ensure a seamless implementation.

“Ever since we put the first Toro LH625iE straight into a production environment more than three years ago, these loaders have been the backbone in our production system, exceeding our expectations, and we look forward to incorporating these new automated units into our operation.”

Kiruna was among the industry’s earliest adopters of cable-electric loading, trialling its first Sandvik unit in 1985. The oldest of Kiruna’s Sandvik LH625E loaders was 13 years old and had more than 40,000 production hours when what began as a project to modernise the loader and a side project to enhance its cable reeling system ultimately evolved into a completely upgraded loader model with the latest technology and new components.

Sandvik collaborated closely with LKAB to customise the design of Toro LH625iE to meet Kiruna’s needs. These included better energy efficiency than the original model with the same payload capacity and a larger, more ergonomic operator’s cabin with a turning seat that swivels 180°.

Mats Eriksson, President of Sandvik Mining and Rock Solutions, said: “[The] Toro LH625iE has proven itself at the Kiruna mine, delivering an unrivalled production capacity of up to 500 metric tons per hour. Not only are these automated loaders extremely productive, they improve underground conditions and operator comfort with less heat, fewer vibrations and lower noise levels. Our partnership will create value for LKAB for years to come, and we look forward to continuing to support LKAB’s goals to mine more sustainably and productively.”

The Toro LH625iE is 14 m long and features a 4-m-wide, 9 cu.m bucket and an energy-efficient, IE4 classified electric motor to deliver a low cost per tonne. It connects to Kiruna’s mine network via a 350-m trailing cable that enables an operating range of up to 700 m.

Sandvik completes acquisition of Polymathian, strengthens Deswik mine planning offering

Sandvik has completed the previously announced acquisition of Polymathian Industrial Mathematics, in the process becoming a part of its Sandvik Mining and Rock Solutions’ Business Unit Deswik.

Polymathian’s solutions for automated decision making and optimisation complements Deswik’s suite of mine planning software and consulting services while remaining OEM agnostic, the OEM said. Deswik, a leading mine planning software company, was previously acquired by Sandvik in April 2022.

Matt Chilcott, CEO of Deswik, said: “We are very excited to welcome Polymathian to the Deswik family. Our employees have been the driving force behind our success. Introducing the talent, experience, and innovative technologies of the Polymathian team will position us to deliver even higher value to mining operations globally.”

The addition of Polymathian to Sandvik Mining and Rock Solutions broadens the offering and is another step towards enhancing the productivity of the mining customers’ value chain, it said. Combined with Deswik’s software solutions, the acquisition creates a “unique digital portfolio” that will help customers optimise their data driven operations.

Polymathian’s co-Founders, Dr Ben Hollis, Jonathon White and Steven Donaldson, will join Deswik’s senior management team and continue to lead the development of Polymathian’s software suite and technology platform.

Hollis said: “We are thrilled to be joining the Sandvik Group and believe that our combined expertise will lead to great advances in the field of data analytics for the mining industry. We look forward to leveraging Sandvik’s global reach and resources to bring our software solutions to even more customers around the world.”

Sandvik to pair Polymathian portfolio with Deswik solutions for ‘unique’ combination

Sandvik has signed an agreement to acquire Polymathian Industrial Mathematics, an Australia-based provider of advanced mine optimisation software and services.

Polymathian will be reported in Digital Mining Technologies, a division within business area Sandvik Mining and Rock Solutions (SMR), Sandvik says.

Polymathian’s solutions for automated decision making and process optimisation complements the offering of Deswik, a leading mine planning software company which Sandvik acquired in April, the company added. Its product offering includes mining operations optimisation and simulation software for areas such as extraction process, material flow, energy and fuel consumption, and maintenance efficiency. It counts several of the world’s largest mining companies as customers.

Stefan Widing, President and CEO of Sandvik, said: “With the acquisition of Polymathian we continue to broaden our offering to enhance productivity in our mining customers’ value chain. Polymathian’s automated decision making and process optimisation, together with Deswik’s software tools for planning and managing production, represent a unique combination in the market.”

Polymathian will be a part of Business Unit Deswik and remain OEM agnostic, according to Sandvik.

The acquisition will enable Sandvik to further accelerate the development of its end-to-end optimisation, battery-electric vehicle (BEV) and AutoMine® offerings, by leveraging Polymathian’s unique skillset and platform, it added.

Mats Eriksson, President of Sandvik Mining and Rock Solutions, said: “Polymathian is a great addition to Sandvik Mining and Rock Solutions, and enables SMR to now have a unique digital portfolio that will help our customers to optimise their data-driven operations across the value chain and ensure their mine design is fully compatible with technologies like AutoMine and BEVs. I am very pleased to welcome Polymathian to the Group.”

Polymathian was founded in 2013, has 50 employees and is headquartered in Brisbane, Australia. The company’s annual revenues per June 2022 were around SEK100 million ($9.6 million). The transaction is expected to close during the March quarter of 2023.

Polymathian finds funding for automation work at OZ Minerals’ Carrapateena

Polymathian will be spearheading a A$2 million ($1.5 million) industrial mathematics project funded by industry partners and METS Ignited, and focused on OZ Minerals’ Carrapateena mine in South Australia.

This project will form part of the Industry Growth Centre’s latest Tranche 4 Collaborative Project funds totalling a combined investment of A$6 million, METS Ignited said.

The grant was awarded to Polymathian’s project at OZ Minerals’ Carrapateena copper-gold mine where, in collaboration with OZ Minerals, Downer, Deswik and others, the company is applying industrial mathematics to deploy the world’s first highly automated short interval control (SIC) system for the near real-time optimisation of sub-level cave development and production mining.

Project Lead and Partner at Polymathian, Steven Donaldson, said: “This funding allows us to marry industrial mathematics, automation and mine planning to optimise asset value at Carrapateena and explore how SIC can be done going forward.”

By applying industrial mathematics to the SIC process, the project collaboration automates the optimisation of the mine plan and autonomously dispatches tasks to the underground fleet by responding to live data.

Plans can be updated to respond to dynamic changes in the mine, as live data is received and assumptions change, according to the company. For example, at a weekly level, plans are updated as required for a rolling seven-day window, rather than on a set schedule for a fixed seven-day period. This avoids having fixed weekly plans that are at risk of becoming out-dated.

Matthew Fargher, OZ Minerals’ Senior Engineer for Long Term Planning at Carrapateena, said: “This project pursues a world first in mine planning where the mine plan is autonomously optimised and tasks dispatched in semi real-time to the underground fleet. By doing so, we can potentially remove value destroying constraints such as self-imposed time horizons and subjectivity in decision making to deliver the next best decision.

“We are excited to be a part of the team that’s delivering the blueprint for mine planning and executional change globally.”

Donaldson added: “The potential market for this tool is really quite large as the way we are solving the problem is very generic. We see this solution having potential to optimise operations across all hard-rock underground mines in Australia and globally.”

The project also has the potential to create new jobs at Polymathian including accelerating the growth of its newly opened Perth office.

METS Ignited Chief Executive, Adrian Beer, says the quality and capability of the funding applicants is becoming increasingly more sophisticated, with a number of the solutions having broader applicability across a number of sectors.

“This round of project fund recipients demonstrates just how capable our leading global METS sector is, and what is possible within our local technology sector,” Beer said.

“We are extremely proud of what has been achieved by the project fund recipients to date, and this new addition to the project funding shows that we have a huge potential to build upon.”

METS Ignited to fund four collaborative mining technology projects

In line with the Federal Government’s recently published Modern Manufacturing Strategy, METS Ignited has announced the latest award of projects as a part of its Industry Growth Centre collaborative project funds.

It has announced the award of METS Ignited Tranche 4 Collaborative Project Funds, with the combined investment of over A$6 million ($4.3 million) from METS Ignited and industry partners going to AMOG Pty Limited, Gekko Systems, Polymathian, and Universal Field Robotics.

The fourth round of the funds focused on the application of analytics, automation and robotics in the mining industry. The selected projects have originated in the local market, are industry-led, and are projected to deliver a high degree of global impact potential and substantial benefits to the METS sector, according to the group.

The success of these four projects with over 17 industry partners in total is projected to deliver almost two hundred new roles, and generate a combined revenue contribution of over A$100 million for the sector, it said.

“METS Ignited’s role as an Industry Growth Centre is to lead collaboration between Australian mining equipment technology and service (METS) companies, global suppliers, mine operators, research organisations and capital providers to support the improved productivity, competitiveness and innovative capacity of the Australia’s world-leading METS sector,” METS Ignited said.

METS Ignited Chief Executive, Adrian Beer, says the quality and capability of the funding applicants is becoming increasingly more sophisticated, with a number of the solutions having broader applicability across a number of sectors.

“This round of project fund recipients demonstrates just how capable our leading global METS sector is, and what is possible within our local technology sector,” Beer said. “We are extremely proud of what has been achieved by the project fund recipients to date, and this new addition to the project funding shows that we have a huge potential to build upon.”
