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.”

Mobilaris’ new devices to leverage latest communication, machine-learning tools

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.”

Mobilaris Onboard easing the traffic flow at underground mines

One of the features of the new Mobilaris Onboard™ real-time situational awareness technology can, according to Hans Wahlquist, VP Business Development & Strategic Product Management for Mobilaris Mining & Civil Engineering, solve the majority of an underground mine’s traffic congestion issues without the need for any additional infrastructure.

As Wahlquist says, traffic congestion is one of the biggest time thieves in a modern underground mine.

“Even as there are bays to park in and let someone pass by, it is difficult to know if there is anyone coming my way,” he says. “Additionally, if I do know about an incoming machine or vehicle, it is still a possibility that the parking spot I am planning to use is already occupied by another vehicle. Simply put, using the radio to avoid traffic congestions is not a perfect solution.”

A traditional approach to solve this is the creation of an advanced traffic management solution where traffic lights would be controlled in order to manage the traffic. Solutions like this are expensive to build and deploy, according to Wahlquist.

“Luckily, these problems can now easily be mitigated with the advent of a new revolutionary product called Mobilaris Onboard using the patent pending Mobilaris Hybrid Positioning™ technology,” he said.

“With the advent of Mobilaris Onboard mounted inside a vehicle, you will get a virtual ‘radar’ that warns you about any vehicles coming your way. As the Mobilaris Onboard knows about all assets in the mine and who is moving and in what direction, together with its own location and direction with an accuracy of 5-10 m, we can create an early warning before a potential traffic situation,” he said. “This enables you to sort out the situation before it will turn into a problem.”

This new feature is called Traffic Awareness.

“We are confident that Traffic Awareness will solve the majority of your traffic congestion issues without any additional infrastructures for high precision positioning or traffic management solutions,” Wahlquist says. “The theory is simple but powerful, if two vehicles meet and both drivers see each other, they will directly know who should give way to whom.”

Investigations have shown traffic slowdown in ramps and other areas with dense traffic are one of the biggest contributors to lost productivity.

Wahlquist explained: “From a recent study at a Canadian mine, a truck round trip from stope to rock breaker averaged 20 minute; as small as 10 minutes, and as large as 50 minutes. The large variation in ramp time could be attributed to, in part, congestion on the ramp and/or rock breaker. By reducing the longest round trip from 50 minutes to, say, 35 minutes (but not changing the average), an extra three to four trips could be possible per shift. This would be facilitated by Onboard to keep ramps and haulage ways clear for priority truck traffic. Queuing time at the rock breaker could also be reduced as truck travel time becomes more repeatable.”

In addition to the productivity gains that Traffic Awareness enables, the effects on safety are huge, according to Wahlquist. “Traffic Awareness is not the same thing as a Collision Awareness system (CAS). Instead it gives drivers the needed awareness and a very early warning that something is coming their way. It will not replace CAS or Proximity Detection Systems but instead work as a very important complementary ‘long range’ system.”
