OZ Minerals navigating Carrapateena mine traffic issues with Mobilaris solutions

OZ Minerals, through the implementation of Mobilaris Situational Awareness and Mobilaris Onboard, has improved traffic flows at its Carrapateena copper-gold mine in South Australia, according to a recent case study.

Having implemented the solutions from Mobilaris, owned by Epiroc, the mining company gained a better understanding of where machines and people were physically located underground – and operations became safer.

Since commencing production in December 2019, the Carrapateena mine has become, over the past decade, one of the biggest mining projects in the state. The ore must be hauled from the production levels to the crusher level via a short decline with limited passing areas, which poses challenges.

To optimise haulage flows, OZ Minerals deployed Epiroc’s Mobilaris Mining Intelligence decision support system to digitise the mine.

Daniel Bruce, Superintendent, OZ Minerals Carrapateena, said: “We saw potential to remove some of the constraints we have underground. You can’t see around corners, and you can’t see through rock, so understanding where things are – where people and machines are – is a lot more difficult than in a typical workplace on the surface.”

OZ Minerals rolled out the first feature in 2019: Mobilaris Situational Awareness, a solution for surface control room operators. Mobilaris Onboard, a solution for underground operators in vehicles, followed in 2021. Thanks to real-time 3D visualisation, anybody with access to a tablet or a PC can quickly understand where machines are operating, according to Epiroc.

“Mobilaris Situational Awareness allows you to see, live, at any point in time, where all the equipment and people are in the mine,” Bruce said. “It also allows you to navigate to locations, equipment and refuge chambers.”

OZ Minerals had initially installed Wi-Fi tags on all its vehicles, which provided accuracy to around 150 m. With Mobilaris Onboard, it can achieve location accuracy of 5-10 m without any extra infrastructure, and all that is needed are basic OBD2 adapters or a Doppler radar, Epiroc says. Implementation started with trucks and loaders, and now the entire underground fleet has been equipped.

This has significantly improved real-time position information, according to Amelia Schmidt, Senior Technician in the site operations team at Carrapateena.

“Everyone at the site operations centre – dispatchers, mine controllers and haulage control – is now using Mobilaris Situational Awareness,” she said. “Previously, it could take quite a bit of time to search for a piece of equipment, but it only takes seconds now to see its last location.”

The system also helps OZ Minerals with its fleet management – to determine where trucks are, for instance – thus becoming a tool in the decision-making process.

Schmidt said: “For those who are perhaps new to the mine, we’ve been able to insert points of interest on the map, for example where it is best to hold. Cycle times are well managed, despite underground operations becoming a lot busier.”

OZ Minerals then implemented a second Mobilaris feature: Mobilaris Onboard, a tablet in a vehicle that acts just like a car navigator but without any need for a dedicated tracking infrastructure. This provided everyone underground with a tool that enabled them to easily understand how equipment was positioned around them.

Bruce added: “This is another piece of information that the operator can use to make a decision – and all of these minute decisions add up to a more productive and safer workplace.”

For Carrapateena Truck Captain, Joel Dodd, everyday work has become easier thanks to Mobilaris Onboard.

“One of the main benefits is that we’re able to travel down and get to our locations a lot better,” he said.

OZ Minerals now has around 200 tablets in vehicles underground – in trucks, LHDs, face drill rigs and light vehicles – and the feedback has been very positive.

“When people can see more clearly where other people are, it helps them avoid unwanted interaction,” Bruce said.

Epiroc equipping LKAB Kiruna personnel with new Mobilaris safety solutions

LKAB is further increasing its safety capabilities by implementing several solutions from the Mobilaris Mining Intelligence platform at its Kiruna mine in northern Sweden, Epiroc says.

The platform, now 100% incorporated into Epiroc following the consolidation of its ownership in Mobilaris MCE AB in 2021, allows all employees to receive alarm and crisis information and confirm directly on their mobile phones in an emergency situation, Epiroc says. Employees can also obtain position support and the ability to navigate faster to rescue chambers with the help of applications on their mobile phones.

This means rescue personnel will now have the tools and means to manage emergencies better and faster, according to the OEM.

Joel Kangas, LKAB’s Kiruna Mine Manager, said: “We want to shorten the time from when an alarm goes off to when everyone is safe, and we believe this digital solution can help us with that.”

Hans Wahlquist, Global Director of Product Management at Epiroc, said: “LKAB already has a high level of safety, but now there are new technologies and new opportunities, and they have the infrastructure required for this installation. This project will give everyone in the mine more information about the situation in real time.”

LKAB is setting a new world standard for mining where digitalisation forms an important step towards easier, safer and more efficient work in the mine. The mobile safety solution project is a collaboration between LKAB and Epiroc, involving both existing products from Epiroc and new developments. The project began in the autumn of 2022 and the goal is to start rolling out the solution in the spring of 2023 at the Kiruna mine.

Andreas Ericson, General Manager Epiroc Mining Intelligence, said: “Collaborations with customers are crucial for finding innovative solutions. This project demonstrates the potential for digital transformation in the mining industry, bringing us one step closer to a smarter and more efficient future.”

The following four modules from the Mobilaris Mining Intelligence portfolio are included within the project:

  • Location of people with the ability to receive alarm and crisis messages on their mobile phones through Mobilaris Situational Awareness and Mobilaris Virtual Tag;
  • Distribution of emergency messages and support provision for getting people to safety through Mobilaris Emergency Support;
  • Three dimensional map in vehicles for navigation assistance, increased traffic safety and the ability to quickly find the nearest rescue chamber through Mobilaris Onboard; and
  • Three dimensional map on the employee’s mobile phone for navigation assistance and the ability to quickly find the nearest rescue chamber through Mobilaris PocketMine.

Gold Fields keeps modernising Granny Smith with Mobilaris solutions

Gold Fields has implemented both Mobilaris Onboard and Mobilaris Situational Awareness at its Granny Smith underground mine in Western Australia as part of an ongoing modernisation program.

In 2018, Gold Fields launched a five-year modernisation program for the site. The first phase’s ambition is to ensure cost efficiency, productivity and a safe work environment by integrating data-driven solutions into the mine.

Michael Place, Mine Manager at Granny Smith, said Gold Field has three dedicated full-time personnel to work on the modernisation program. It has also employed external consultants and contractors to assist with the integration.

“Together, we integrate an underground LTE system to have full connectivity in the mine,” he said.

Gold Fields’ investment will also have environmental effects over time as its digitalisation allows the company to work more sustainably.

“Moving into a more digital world is going to make sure that we are sustainable long-term,” Place said. “For instance, we can maintain our cost profile during expansion and follow up on our environmental footprint.”

Historically, underground blasting has been one of the biggest time thieves in the Granny Smith Mine, with the operation currently losing four hours of production in a 24-hour period due to the firing. With the ongoing modernisation program, Place looks for the mine to become more efficient than before.

“Integrating technology into the mine allows us to look at options to reduce the inactive time,” he said. “We can increase efficiency through autonomous equipment, remote operations, and digital solutions. The expected outcome is a 5-15% increase in productivity.”

The Granny Smith Mine has close to 4,000 different locations, with over 100 employees underground at the same time. It already runs 1.2 km deep and, like many mines, is under constant development.

In 2019, a group from Gold Fields Granny Smith, including General Manager, Andrew Bywater, visited Boliden in Sweden to study the use of the Mobilaris product suite, with focus on Mobilaris Onboard and Mobilaris Situational Awareness in the Kristineberg mine.

Mobilaris Onboard, working as a machine navigator underground, creates traffic awareness and a safe and effective traffic flow, according to the company. Based on real-time data, Mobilaris Situational Awareness enables transparency and awareness. The information makes it possible to control the operations and resources, and people can quickly act upon what is happening and make smart decisions faster, Mobilaris says.

Because Mobilaris data and positions were shared in real time, the operation had seen an increase in safety and efficiency, according to Mobilaris.

This visit has since led to Gold Fields implementing both Mobilaris Onboard and Mobilaris Situational Awareness at its underground operations at Granny Smith.

Place said: “Mobilaris Onboard allows us to navigate to all locations underground quickly and efficiently. It will improve our productivity and decrease inactive time by reducing traffic congestion and finding equipment and machines faster.

“We are a haulage-constrained mine and, by reducing the cycle time of our haulage fleet, we can raise our productivity. It is a significant benefit.”

Strong customer relations allows Mobilaris to develop and test all products in real environments, as well as the possibility to bring companies to customer’s sites to experience the products in use, Mobilaris said.

“Our close relationship with the customer is a crucial success factor for Mobilaris,” Pascal Hansson, Sales Director, Mobilaris Mining & Civil Engineering, said. “All our solutions are tested in Boliden’s and other companies’ underground mines. This gives us the confidence to deliver what we promise to our customers.”

Gold Fields has plans to use Mobilaris Situational Awareness as its number one source of information and integrate it with fleet management, inventory systems, and the daily shift scheduler, according to Mobilaris. The mine’s digital investment is expected to pay off within a year, it added.

Place explained: “The location data will synchronise with daily schedules to ensure real-time data is captured from the time jobs are planned and executed. We are looking at efficiency improvements, but we are currently introducing this technology to maintain our production profile with the increasing depth and costs.”

The Gold Fields modernisation program has full support from top to bottom and is expected to be finished over the next two years, Mobilaris said.

During the research process, Gold Fields discovered that Mobilaris Onboard addresses specific safety issues. By sharing positional data and navigation in 3D, drivers can avoid traffic congestion and find shelter during emergencies.

Place said: “We have installed tablets in all our heavy vehicles. With Onboard’s traffic awareness feature, we can minimise the vehicle-vehicle interaction and the vehicle-personnel interaction. The application also tells us where to find the three nearest refuge chambers to our location. So, if there is an emergency, we can get the quickest path to safety.”
