Newmont Corporation is expanding its use of next generation 5G wireless networks to improve safety in underground mining following trial results from its Cadia mine in New South Wales, Australia.

In February last year, Newmont (Newcrest as it was then) announced a trial of 5G in partnership with Ericsson and Telstra Purple at its Cadia mine – one of the largest underground gold-copper mines in the world.

Before the trial, Cadia was limited to upload speeds of 20-30 megabits per second (Mbps) using Wi-Fi to operate autonomous equipment such as ore loaders and remote-controlled mining machines.

These Wi-Fi connections were unreliable and unpredictable when under load, according to Newmont. There was insufficient capacity to operate the required number of machines in the one area at the same time, particularly with the amount of video upload involved, and automation safety stops were regularly falsely triggered due to network packet loss.

Using Ericsson Private 5G, Newmont was able to demonstrate the ability to achieve upload speeds of around 90 Mbps along access drives and declines throughout the underground complex, and 150 Mbps upload and 500 Mbps download on all-important extraction drives, it says.

The connections underground were found to be persistent and highly dependable, resolving historic limitations experienced with Wi-Fi and providing the consistent performance essential for remote control and autonomous mining systems.

Newmont Chief Safety and Sustainability Officer, Suzy Retallack, said: “The trial results show the extraordinary potential of 5G to improve safety, increase the number of machines that can be operated on a single network and boost production efficiencies in underground mining.

“These trials are part of the new frontier of technology in mining – using innovation to make our people safer and our mines more productive.”

Newmont will now use 5G to roll out more autonomous fleet like drill rigs, graders and auto haul trucks as part of future mining operations, relying on 5G’s unique capacity and capability to facilitate and streamline operational capabilities while deploying additional safety systems like radars and collision avoidance to improve overall mine safety systems, it says.

Head of Private Cellular Networks from Ericsson, Manish Tiwari, said: “5G is enabling rapid global transformation of industry, supporting digitalisation and movement towards automated, more efficient, and safer operations across a number of sectors.

“Ericsson is proud to be partnering with Newmont on demonstrating the potential of 5G to the global mining sector.”

Trialling 5G New Radio (NR) technologies on the surface at Cadia as part of the same initiative also demonstrated that new 5G innovations, such as 64T64R Massive MIMO, beamforming and beam-steering provided a leap forward in available throughputs at the extended distances found in surface operations.

Newmont says it uses technology to make workers safer while improving efficiency. On the basis of the trial, 5G now has a firm place in Newmont’s communications strategies for Cadia and its other Tier One underground and surface mines across the world.

Following support for the Cadia 5G trial from the Australian Communications and Media Authority (ACMA), Newmont has now applied to ACMA for Area Wide Licenses to extend and embed Newmont’s use of 5G technology across its Australian operations.

Newmont is now planning to expand the use of 5G networks across its global network of Tier One underground gold-copper mines.

Newcrest, Ericsson and Telstra Purple to trial 4G LTE and 5G tech at Cadia

Newcrest Mining will trial advanced 4G Long-Term Evolution (LTE) and 5G mobile technologies underground at its Cadia mine, in New South Wales, Australia, to assess the potential of cellular delivery of data and video to support a smarter, safer and more sustainable mine, it says.

In partnership with Ericsson and Telstra Purple, Newcrest will deploy a private 4G LTE and 5G trial network in its underground operations at Cadia in the coming months. This announcement follows previous engagements where the trio worked to improve communications coverage, performance and safety with private 4G LTE at its Lihir mine in Papua New Guinea, and more recently for surface operations at the Cadia Valley Operations (CVO).

Speaking at the Sweden-Australia Sustainable Mining Summit in Sydney, Australia, today, CVO General Manager, Aaron Brannigan, said modern mining is a data-driven business, with technology and digitalisation creating new levels of productivity and safety, greater efficiency and reduced environmental impact.

“In the ongoing quest for productivity, efficiency and safety, Newcrest must use every tool at our disposal to boost performance at site while continuing to ensure that everyone at our mines gets home safely at the end of the day,” he said. “With 4G and 5G mobile technologies potentially offering better performance and capabilities than Wi-Fi, this trial will help Newcrest to assess its viability for greater coverage, capacity and functionality to support advanced underground automation, our Connected Worker strategy and future growth at Cadia.

“It’s an exciting time for Newcrest and for Australian mining, and this is a great practical example of how Australia’s biggest industry can leverage Australia’s position as a global 5G leader to further drive digitalisation in the mining sector and help develop a smart, safer and more sustainable mine.”

The trial will use Ericsson’s Private 5G (EP5G) solution for Industry 4.0 enterprises to assess different cellular approaches for coverage and capacity needs and deployment economics. It will include the use of various 4G and 5G radio types, massive- and multi-user MIMO (multiple-input-multiple-output) advanced antenna systems for high density and high capacity connectivity requirements, and Uplink Booster technology derived from custom-made Ericsson Silicon system-on-a-chip 5G processors to increase uplink signal strength and data throughput, Newcrest explained.

Ericsson’s Head of Australia and New Zealand, Emilio Romeo, said: “5G connectivity will be instrumental in enabling advanced teleremote and autonomous technologies, which are integral to industries such as mining. We’re delighted to be working with Newcrest and Telstra Purple to trial Ericsson’s 4G LTE and 5G solutions, and enable Newcrest to develop know-how on how to best deploy them underground.”

Telstra Purple Digital Transformation Executive, Paul Nicholls, said: “We’ve been thrilled to see what our 4G LTE and 5G mobile network technologies have been able to do through this project, from supporting wireless mining applications underground, to boosting safety for the local team. These technologies are absolutely transformative for a broad range of industries, and it’s exciting to be part of industry 4.0 innovation in Australia.”

EU competition, collaboration and connections helping Epiroc solve mining challenges

Epiroc’s start-up mentality is enabling it to continue to solve the mining industry’s biggest challenges, but it is not doing this alone, according to Katarina Öquist, R&D Manager of Technology and Innovation in the Underground Division.

Speaking ahead of her appearance at the EIT Raw Materials Summit 2022 in Berlin, Germany – taking place on May 23-25 – Öquist said access to other industry partners, academic institutes and start-ups through initiatives like EIT Raw Materials continues to help the company overcome challenges the sector throws at it.

“Specifically on the EIT Raw Materials project, there is the possibility to take in young start-ups and academic institutes, which can prove key when considering the ‘kicks‘ the funding can provide such companies and initiatives,” she said. “It is important for these young technology companies to have a connection to applications, being able to test out concepts and ideas in a real-world environment with companies like Epiroc, and, at the same time, introduce new thinking into industries such as mining.”

This wide scope of participation is increasingly required when considering the future direction of the mining industry, according to Öquist.

“If you look at the mining industry, and the part I am in with Epiroc, we are experiencing the biggest technology shift ever,” she said. “We are looking at electrification, autonomy and digitalisation all at the same time. All of these have interdependencies and connections in between, which make it quite complicated.

“When I started in the start-up sector some 15 years ago, you often were looking to solve one problem, but, today, you are not offering the sole solution; you must interact with a much bigger technology ecosystem.

“For this, collaboration is very important.”

In this regard, EIT Raw Materials and European Union Commission funding are more important than ever, ensuring all stakeholders are connected and focused on coming up with workable solutions for industry to achieve their lofty ambitions.

While not tied to EIT Raw Materials, the NEXGEN SIMS project is a good example to highlight here.

NEXGEN SIMS builds on the EU-sponsored SIMS (Sustainable Intelligent Mining Systems) project, which aimed to demonstrate new technology and solutions for the mining industry. Running from 2017 to 2020, the SIMS project resulted in, among other things, the Epiroc line of battery-powered mining machines.

NEXGEN SIMS, meanwhile, is a consortium of 13 partners collaborating in an EU-sponsored project to develop autonomous, carbon-neutral, sustainable mining solutions, building on the SIMS success. The partners are Epiroc Rock Drills, AFRY – ÅF Digital Solutions, Agnico Eagle Finland, Boliden Mineral, Ericsson, KGHM Cuprum, KGHM Polska Miedź, K+S Minerals and Agriculture, Luleå University of Technology (LTU), LTU Business, Mobilaris MCE, OZ Minerals and RWTH Aachen University. The project, led by Epiroc, has a budget of €16 million ($16.8 million) and will run from May 2021 to April 2024.

“In the case of NEXGEN SIMS, it is built on a known partnership including new partners,” Öquist said. “After being involved with the majority of these partners since SIMS, we build from a high level of trust, which increases the possibility of success, especially concerning integration.

“Europe, in general, is very good in facilitating these type of collaborative projects that involve all segments of the innovation ecosystem – start-ups, industry partners and academics.”

According to Öquist, the NEXGEN SIMS project remains on track, with the integrations between electrification, automation and digitalisation likely to hold the most exciting outcomes for the wider mining industry.

For its part, Epiroc is also helping accelerate the development of start-ups of its own, taking stakes/interests in key technology providers and allowing them access to its much larger network.

ASI Mining, FVT Research and Mining TAG represent just a few examples here.

Öquist expanded on this with a reference to Mobilaris MCE, a company Epiroc acquired outright just last year, after five years of holding a 34% stake.

“They (Mobilaris MCE) started off in 1999 as a start-up from the telecoms business,” she said. “Due to them being in the northern part of Sweden, they tagged onto the mines and we ended up acquiring a minority interest in them.

“In the five years since, they have had a nice journey under the guise of Epiroc. They represent a local small start-up growing by going under the wings of a much larger industry partner.”

Epiroc, too, has benefitted from this collaboration, with Mobilaris MCE’s situational awareness technology recently becoming a key part of the OEM’s 6th Sense digital solution.

Not all OEMs would be willing to facilitate the growth of other companies in such a way, but Öquist, who has only been in her role with Epiroc for two years, puts this down to the company‘s unique culture.

“We call ourselves a 150-year-old start-up,” she said. “Regardless of how big we grow, that mindset remains – if someone highlights a problem, we set out to solve it through both internal and external collaboration.”

MTS, Ericsson deploy Russia’s first commercial 5G-ready private network at Polymetal’s Nezhda

Mobile TeleSystems PJSC, a leading provider of media and digital services, has completed the construction and launch of operations of what it says is Russia’s first commercial 5G-ready Private network at Polymetal International plc’s Nezhdaninskoye gold deposit in the Republic of Sakha (Yakutia).

The planned installation of the network, built on the Ericsson Dedicated Networks solution, was announced last year.

Within the project, MTS deployed a wireless network for Yuzhno-Verkhoyansk Mining Company JSC, affiliated with Polymetal. The network supports integrated mining dispatching systems, positioning, remote and automated control of various equipment, including excavators, drilling rigs, measuring devices, monitoring systems for remote equipment and video monitoring.

Within the project a full range of turnkey works and services has been implemented, including site inspection, network architecture design, supply and installation of radio base stations, network core and auxiliary equipment, network testing and commercial launch, MTS says. At the first stage, the network built on Ericsson solutions will operate in the LTE standard with the possibility of smooth and fast upgrade to 5G, according to the company.

The network is built on Ericsson Dedicated Networks solution, which complies with the 3GPP standards and includes a full-fledged carrier-grade network core. It supports 4G and 5G Non-Standalone (NSA) simultaneously and allows dual-mode core capability to support 5G New Radio Standalone (5G NR SA). An enterprise can use all the carrier grade packet network functions for its own mission-critical applications, MTS says.

Georgy Dzhabiev, Director, Digital Solutions, MTS, says: “We are grateful to our partner Polymetal for cooperation that resulted in the creation of the first commercial Private LTE network in Russia for remote monitoring and managing critical processes in difficult geographic and weather conditions. I am sure that the competence and experience of MTS in the implementation of unique network and IT solutions, digitalisation and automation of production processes will help our customers to increase their business efficiency and improve the working conditions.”

Alexander Laguta, Head of Information Technology and Communications department, Yakutsk branch of Polymetal, says: “The system is already showing its effectiveness and is ready to move to next stage of introducing innovative technologies in production. The Private 5G-ready network will significantly increase the speed of transferring large amounts of data and reduce the cost of maintaining the technological network. One of the first projects on the basis of this network will be launch of dispatching systems, remote control of drilling rigs and video monitoring.”

Alexander Romanov, Head of Private Networks, Ericsson Russia, says: “The Private Network is the backbone of critical communications infrastructure and the Industrial Internet of Things, not only in mining, but also in other industries with a high demand for seamless coverage, performance, security and reliability while supporting mission-critical business processes in a new digital reality.”

At the next stages of the project, the implementation of a dispatch radio communication system based on MC-PTT (Mission Critical Push-to-Talk) over LTE network is planned, along with integration with the internal telephone network of the enterprise.

Intent on “mastering the latest technologies” in its domain, Mobilaris says it will focus on the use of next-generation communication technologies such as 5G and Wi-Fi 6, and artificial intelligence, to build out its new safety solutions in 2021.

Mobilaris says it is building a device using 5G technologies that will be used in a new offering for Mobilaris Industrial Solutions.

By leveraging these new technologies, it will bring Industry 4.0 digital workforce safety to all its customers, it said.

To ensure this new device is “truly world-class in terms of safety, performance and resilience”, Mobilaris has partnered with Sigma Connectivity and Ericsson to leverage their expertise in this domain. It says it is the first company to use the new reference cellular IoT design from Ericsson called Ardesco.

The company said: “5G and cellular IoT are technologies that will open up new possibilities, but they need connection to existing public mobile networks, or private networks. Therefore, Mobilaris has partnered with Telia to bring our new solution to the market.”

Earlier this year, the company joined Telia’s 5G program as a new member and, after that, secured a commercial partnership to bring solutions to the market while at the same time tailor its use of the Telia network to maximise performance and efficiency.

Another key technology for next generation communication solutions is Wi-Fi 6.

Mobilaris has been deploying Wi-Fi-based solutions for many years, with 2021 representing no change to the status quo.

“Many of our customers have Wi-Fi networks, and we are continuing to invest in this technology to secure our capability to meet all customer demands and to innovate, leveraging the new additions coming in Wi-Fi 6, 6E and beyond,” it said.

This is where a partnership with Aruba will bring best-in-class, real-time situational awareness to industry customers around the globe, Mobilaris said.

The use of artificial intelligence is also nothing new for the Sweden and US-based company. It has already deployed its Mobilaris Onboard product in several mines across the globe and, at its core, machine learning is creating “value for our customers” that would not have been possible just a few years ago, it says.

It concluded: “Moving ahead, we are continuing to invest in AI to further accelerate our products and solutions and we expect to announce several new research partnerships here within the near future.”

Boliden, Ericsson and Telia celebrate world first 5G underground mine network deployment

Automation, Communications in mining, IoT, Mine operation news, Mining equipment, Mining services, Mining software, , , , , , , , , ,

SIMS project partners Boliden and Ericsson, together with Telia, say they have deployed the world’s first 5G network using New Radio in an operational underground mine, the Boliden Kankberg mine in Sweden.

The deployment comes less than a month since Telia and Luleå University of Technology, in Sweden, inaugurated a 5G-testbed as part of its Wireless Innovation Arena project.

The Kankberg mine is located around 10 km west of the Boliden Area Operations process plant in Boliden, and produces gold and tellurium. The mine has been in production since 2012 and has since then increased the annual production capacity to around 450,000 t. In 2018, the mine produced 456,979 t grading 4.4 g/t Au, 10.7 g/t Ag and 188.3 g/t Te.

SIMS, or Sustainable Intelligent Mining Systems, is part of the Horizon 2020 program, the biggest EU-backed research and innovation program ever with nearly €80 billion ($90.1 billion) of funding available over seven years (2014 to 2020).

“Productivity and safety requirements are very high in the mining industry. This customer configured network can function standalone, allowing mining operations to continue even if communication is disrupted to the mine,” SIMS said.

The 5G technology is superior to other communication solutions for connectivity in demanding environments like mining and manufacturing where continuous operations and close monitoring of processes are required, according to SIMS. With characteristics like very low response times and the option for local data handling, 5G is the best suited technology to meet the safety and efficiency requirements of the mine, it added.

Magnus Frodigh, Head of Ericsson Research, said: “5G is designed to support industry automation and industrial IoT and will be a platform for innovation in industries. The Boliden underground mine is a great example of a sector with tough requirements that will benefit immediately. [This technology]…will ensure connectivity for applications with high performance requirements.”

Magnus Leonhardt, Head of Strategy and Innovation at Telia, said: “Industry 4.0 is becoming a reality. This is another good example of how 5G can be used to build networks adapted to the customer’s operations. To guarantee safety in the mine, for example, the network must function even if communications to the outside world is disrupted. Reliable communications can now be secured with the network we have built.”

Peter Burman, Program Manager at Boliden, said: “We work actively with robotisation to improve productivity and safety in the mine which requires future proof communication solutions. 5G is an important component enabling advanced automation and by that, a safer and more sustainable mine.”

Volvo CE staying connected to automation trend with 5G collaboration

Automation, Communications in mining, Equipment maintenance, IoT, Mining equipment, Mining maintenance, Mining services, Mining software, Sustainable mining, , , , , , , , , , , , , , , , , , , , , , ,

As the application of automation in underground mines accelerates, several companies have started exploring 5G communications developments in order to handle the massive amounts of data that is being generated from autonomous equipment.

One company interested in exactly this is Volvo CE, which earlier this year, in co-operation with Telia and Ericsson, launched Sweden’s first 5G network for industrial use at its facility in Eskilstuna. The partnership could see the mining and construction equipment company become one of the first in the world to use 5G technology to test remote-controlled machines and autonomous solutions.

IM, as part of its annual focus on Nordic Suppliers (to be published in the June print issue), put some questions to Calle Skillsäter (pictured below), Volvo CE’s technical specialist for ‘Connected Machines’, to find out more about this collaboration and understand what hurdles companies are facing when trying to implement such communications solutions.

IM: What is the justification for investing in 5G technologies with Telia and Ericsson? How much of your equipment is currently controlled remotely or autonomously?

CS: Connectivity is a crucial enabler for automation, which is why this 5G project is so significant for us at Volvo CE and for the construction industry as a whole. We also believe that automation technology is at its most efficient when it is run hand in hand with electromobility – as we demonstrated through the Electric Site quarry project.

Thanks to a prior research collaboration with Telia and Ericsson, in the Pilot for Industrial Mobile Communication in Mining (PIMM) project, and now this established Telia Journey to 5G Partnership Program, we have the possibility to test future connectivity solutions for our machines in mining applications, as well as other potential applications.

Currently we are focusing on our L180H wheel loader remote-controlled prototype, but will soon test 5G on the HX2 concept (pictured above) autonomous hauler as well. There are no autonomous or tele-operated machines from Volvo CE available on the market today.

IM: Most of the 5G investment in mining has, so far, come from the Nordic region; why is this?

CS: That’s right, we do have a rather unique setup in that many Nordic companies are at the absolute forefront of their industries with this technology. Mining companies like Boliden and LKAB are driving the business to be more intelligent and automated, Ericsson & Telia bring the connectivity perspective, ABB bring their experience of automation into the process industry, and Volvo CE and Epiroc bring the machine perspective. It’s certainly the case that the Swedish engineering mindset is very open and collaborative, which is what you need to be if you are to explore the potential of new technologies and new ways of working. We are a small country and we need to collaborate and be on the edge of technology to stay competitive.

IM: Do you expect this region, in addition to Canada, to offer the most immediate potential for 5G automated and remote-controlled technologies in mining?

CS: As I’ve mentioned earlier, we have all ingredients available in the Nordics to succeed in this transformation towards more connected and automated mining solutions. Another strong reason is that we have high demands on health and safety for the people working in the mines. Automation is a key way to improve site safety and reduce the dangers and accidents associated with mining. In addition, automation is our key to staying ahead of our competitors.

IM: What testing have you so far been able to carry out at Eskilstuna? What results have been achieved?

CS: We quite recently inaugurated the new test area for automation and tele-operations, so we are still in the early phase. The initial focus is on the tele-operation of the remote-controlled wheel loader L180H, but we will very soon start testing 5G for the HX2 autonomous hauler concept machine. At the moment, it is too early to reveal any results.

IM: When do you expect to be able to test this out in a real-life underground mining environment?

CS: Tests have very recently been performed within the PIMM Digitalized Mining Arena (DMA) project in one of Boliden’s mines, using LTE wireless 4G communications, the results of which will be announced next month. Testing on a customer site with 5G is not planned yet.

IM: When comparing 5G to 4G technologies, what are the main benefits for mining companies when it comes to using this newer communication infrastructure (aside from lower latency, bandwidth, quality of service, positioning, etc)? What sort of impact could it have on operating costs considering the improved accuracy/responsiveness it brings to automated and remote-controlled operations?

CS: The main benefits are, as you say, lower latency, bandwidth and the quality of connection. But lower latency will also mean that tele-operated machines are more responsive, therefore resulting in much higher productivity. Higher bandwidth also means better video quality, which means a better work environment for the operator. Better video quality also creates a better feeling of presence, which helps to improve productivity. Quality of Service will mean machines are up and running for longer.

IM: How far is the industry away from employing these 5G solutions commercially? What are the three biggest hurdles to achieving this milestone?

CS: It’s too early to say when we think customers will be ready to see 5G solutions available commercially. But the biggest hurdles are:

  • Legislation related to the radio frequencies. There are still a number of open questions here; for example, will there be space for local industrial solutions, or will everything be dedicated to the mobile network operators?
  • Hardware availability. For example, there are not many 5G devices designed for demanding mining environments available right now on the market.
  • Business models. The new technologies will push us to review our business models. Should we continue to sell machines like we are used to?

IM: Do you expect underground mines of the future to be run solely off 5G networks? Or, do you expect a combination of 5G/Wi-Fi?

CS: There is a potential for mines to be run only on 5G in the future. But this is one of the questions that we hope to be able to answer in our coming tests and collaboration with our partners.

Ericsson and Ambra expand 5G partnership for mine automation

Automation, Communications in mining, IoT, Mine ventilation, Mining equipment, Mining safety, Mining services, Mining software, , , , , , , , , , ,

Ericsson and Ambra Solutions have announced a global cooperation agreement to lead automation for the mining industry, providing 5G-ready network solutions to automate ventilation systems, real-time personnel and vehicle tracking, and remote control of machinery like LHDs, haul trucks, drills and other mining equipment.

Ambra has selected Ericsson as a radio partner of choice, with the 5G-ready Ericsson Radio System portfolio enabling Ambra, a turnkey engineering services systems integrator, to simplify network deployments and replace up to 60 Wi-Fi access points with a single Ericsson solution, it said.

Eric L’Heureux, CEO, Ambra Solutions, said: “We are excited to expand our partnership with Ericsson to a global footprint. The Ericsson products are optimal to deliver the most demanding applications used by the mining 4.0 industry. The reliability of Ericsson products enables more predictable, secure and lower-cost connectivity, and mining companies want to use a reliable product that is available worldwide.”

Mission-critical Private LTE, deployed for Ambra’s mining customers, provides new capabilities and possibilities to cost-effectively enable digitalisation of mining-related tasks for open-pit or underground mines, Ericsson said. “Prior to this modernisation, specialised tasks and applications were difficult or simply impossible to achieve across the entire mining coverage area when using legacy ‘leaky cable’ or Wi-Fi connectivity.”

Shannon Lucas, Head of Customer Unit Emerging Business for Ericsson North America, said: “The global mining industry has been vulnerable to challenges of energy consumption, equipment loss, and human safety. We have designed an easy-to-use cellular connectivity solution to address these issues and deliver efficiency through digital transformation, while creating a path to 5G.

“Ambra will sell this solution as part of its portfolio and will partner with Ericsson customers (global service providers) to deliver it, which opens up exciting new opportunities and revenue streams for the service provider.”

Ericsson and Ambra partnered last year to deliver the world’s deepest underground LTE network for the Agnico Eagle mining complex, LaRonde Zone 5, in Abitibi, Quebec, Canada. Located 3.5 km below the surface, the mission-critical private network provides data and voice services across the LaRonde mine site and enables several internet of things (IoT) use cases to improve safety and mining operations. Since then, several applications have been deployed using Ericsson solutions to deliver automation of ventilation systems, real-time personnel and vehicle tracking and remote controlling of machinery like LHDs, haul trucks, drills and other mining equipment.

Agnico said recently that it was looking to expand this 5G network in the ramp area from level 269 to surface and at LaRonde 3.

Epiroc and Ericsson connect on 5G and LTE technologies for mining

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

Epiroc has signed a cooperation agreement with leading communications technology provider Ericsson to jointly help mining companies achieve optimal wireless connectivity in their operations through Long Term Evolution (LTE) and 5G technologies.

Key advantages of LTE and 5G solutions compared with other wireless solutions include better coverage, higher reliability and stronger security, especially when machines are in the same area and share information, according to Epiroc.

The technology, which is for both underground and open-pit mines, has already been tested on Epiroc’s machines at the company’s test mine in Kvarntorp, Sweden, with further testing scheduled before providing solutions to customers.

Epiroc said: “Mining companies are increasingly seeking to digitalise and automate their operations to increase productivity, enhance operator safety and lower cost. This includes, for example, remotely operating machines from a control room, and collecting machine performance data to optimise use of the equipment.”

All of this creates a need for reliable, high-performance wireless connectivity at the mines, it said.

Helena Hedblom, Epiroc’s Senior Executive Vice President Mining and Infrastructure, said the mining OEM is happy to team up with Ericsson so that its mining customers can get the most reliable and high-performing wireless connectivity possible.

“This is a crucial step in our ongoing work to ensure mining customers reap all the benefits, including higher productivity and better safety, made possible by digitalisation and automation,” she said.

Åsa Tamsons, Ericsson’s Senior Vice President and Head of Business Area Technologies & New Businesses, said cellular technology and the introduction of 5G is critical to realising the full value of digitalisation and automation “for smart industries”.

“By combining our expertise in connectivity and Epiroc’s cutting-edge technology in mining equipment, we will be able to ensure stable and secure mining operations, leading to increased utilisation, improved productivity and reduced costs.”

This connectivity tie-up follows a recently-signed agreement between Sandvik and Nokia to further develop solutions for private LTE and 5G technology.

Aitik gets connected to LTE network as Boliden looks at 5G future

Boliden has, for the past few years, been testing out 4G and 5G networks at its mines in the Nordic region and recently went live with 4G (LTE) network services at its Aitik open-pit copper mine in Sweden, Fredrik Kauma, Project Manager, told attendees at the recent Mines and Technology conference in London.

The company, one of the mining sector’s leaders when it comes to employing innovative technology, installed its first underground Wi-Fi network in 2013 and has since come a long way on this connectivity journey.

Today, all of Boliden’s mines have complete Wi-Fi coverage, with the network consisting of some 3,000 installed access points and additional hardware, Kauma said. The company uses this for voice communication and positioning, but also other services such as remote control, machine-to-machine interactions and general data or information access.

In 2016, the company installed a small 4G network in one of its underground mines. Now, multiple upgrades later, the network includes the latest 4G features, in addition to elements considered “borderline” 5G, Kauma said. He credited a close co-operation with Ericsson and its research organisation for this installation as well as the Swedish mobile network operator Telia.

The 4G/5G network covers about 1.8 km of tunnels plus 10,000 m² of other areas (production/workshop/offices/canteen) with relatively few pieces of radio equipment, according to Kauma.

Coverage of a similar area with Wi-Fi would require about three times as many access points, he pointed out.

Kauma said: “We use our 4G/5G network to:

  • “Test and compare connectivity-related capabilities – network speed, coverage, quality, etc;
  • “Learn about operation and maintenance; how to roll systems out, what to monitor, key performance indicators, etc;
  • “Understand more of the business side – what work to do in-house/outsource, what should be part of a service level agreement, etc.”

A direct outcome of this test network has been the recently addition of 4G network services at Aitik, one of Europe’s largest and most efficient open-pit copper mines.

This will allow the company to, primarily, carry out accurate remote control of its fleet of Epiroc Pit Viper blasthole drill rigs.

“But, long-term we believe it will replace our existing production Wi-Fi network,” Kauma said.

The future in 5G

While Wi-Fi does offer Boliden much in terms of connectivity, it cannot match 4G/5G when it comes to robustness and coverage. This is part of the reason the company is pursuing developments with 5G technology.

Equipment tracking is one area that could potentially be improved with 5G, Kauma said.

Today Boliden currently uses “passive” Wi-Fi tags for this task, with active antennas mounted on mining vehicles. The signal reflection is only picked up if the tags face the direction of the active antenna and the vehicle with antenna passes close by. While this system adds a lot of value, it does not currently offer the reliability Boliden would like to see, he said.

With 5G, Boliden expects to have “active”, as opposed to passive, tags, which transmit information on a pre-determined basis.

What Kauma termed “advanced remote control” operation is another area set to benefit from 5G connectivity.

The company already has remote control operations today, but it is either line-of-sight or a pre-determined, repetitive type of remote operation; not advanced.

In advanced remote operations, the performance of the wireless communications network has a direct impact on how well the operator can handle the machine, with control responsiveness and picture quality the main factors here.

According to Kauma, low latency will greatly improve the real-time aspects required for secure and efficient handling of vehicles, machinery and other equipment such as drills, hammers, shovels, etc.

In addition, the Quality of Service concept, where priority of connection is given to certain customers, will guarantee bandwidth needs for a detailed enough video stream to the remote operator – even on a heavily loaded network, he said.

“Higher data rates and increased network capacity will enable remote control on a larger scale than what’s possible on today’s 4G technology,” Kauma said.

The improved connectivity expected to come with employing 5G will also be beneficial for wearable technologies, which Boliden has been trialling to help improve the safety and well-being of employees.

The company recently tested out use of a prototype “smart vest” at one of its underground mines for, primarily, proximity detection, but also to “gain a better understanding of other possibilities that comes with this technology”, Kauma said.

The prototype vest was the result of research cooperation between Boliden, Ericsson, clothing company Helly Hansen and technology firm LightFlex Sweden AB.

In addition to the standard proximity detection functions, lights or reflectors warn the wearer as well as surrounding personnel of potential dangers through different flashing/blinking patterns.

Together with advance camera technology, the lights also aid autonomous machinery to automatically detect humans in dark environments.

Boliden would like to, in the near-future, use wearable technology for the monitoring of employees in physically-demanding environments; for analysis of the immediate environment surrounding employees (extreme temperatures, dangerous air quality, strong vibrations or sounds); and for positioning and situational awareness (ie warnings for approaching vehicles).

Key ingredients to make this a reality include a reduction in power consumption – low power means smaller and longer lasting batteries – a fall in cost, enabling the company to equip its entire workforce, and better network coverage and reliability – hence the use of 5G.

“If 5G delivers on its promise, it will be a critical component enabling wearable technology in an industrial environment like ours,” Kauma concluded.
