Telstra Mining Services has announced a new partnership with South32 for a private 4G LTE network at its Cannington underground silver-lead-zinc mine in northwest Queensland, Australia.

Telstra is now in the pre-deployment stage at Cannington, with the network set to “drive improved safety, automation and mechanisation” at the site and connect staff to vehicles and sensors around the mine at all times, it said.

The underground mine produces about 3 Mt/y and the Cannington team is made up of about 550 full-time employees and up to 300 contractors.

Jeannette McGill, Head of Telstra Mining Services, said: “The high throughput and low latency offered by the system means that staff will be able to control critical equipment without interruption, and South32’s digitalisation strategy will be achievable throughout the mine.”

By adopting 4G LTE underground, the Cannington mine will be able to achieve better operating transparency, condition monitoring and production improvements for staff, machines and other mining systems, driving safety, productivity and efficiency, she added.

Telstra will be building an initial underground network 6.5 km in length using a “private, virtualised core” and LTE radio technologies distributed over leaky feeder cable using LTE-capable bi-directional amplifiers.

McGill said: “Our analysis indicates this to be the most effective solution for underground miners and is capable of adapting to the unique geology and composition of the Cannington mine. It enables access to the latest advances in 4G LTE and NB-IoT, and is also upgradeable to 5G in the future.”

The network being private means it will be a completely standalone mobile network, independent from others, like Telstra’s own public network, she explained. “South32 Cannington will have its own equipment, SIM cards and unique network codes for full autonomy and complete control.”

Providing a modern connectivity platform will allow for more flexible operations as well as scalability and choice in applying various digital solutions, according to Telstra.

“The combination of Ericsson mobile network equipment, Telstra radio spectrum, and leaky feeder solutions from specialist manufacturer METStech provides a unique capability that has made extending LTE underground a more commercially realistic and safer prospect,” McGill explained.

At its full deployment, the Cannington installation will become one of the largest underground mining LTE networks in the world using leaky feeder, according to Telstra.

“We’re excited to help drive South32’s Cannington mine further with this new private network, as it looks to pay dividends to safety, productivity and more,” McGill concluded.

Telstra Mining Services says it has implemented Papua New Guinea’s first private 4G LTE (Long-Term Evolution) mobile network at Newcrest’s Lihir gold mine.

The next generation wireless communications platform will allow for greater levels of safety, remote operation and automation, according to Telstra, which worked with Newcrest to provide design, staging, site deployment and testing of the network.

Every kind of production vehicle asset, including trucks, drills, excavators, dozers, shovels and barges have now been connected and operationally proven over LTE. This process has revealed significant performance improvements in terms of reliability, speed and latency, according to Telstra. “The network has been able to resolve challenges with existing Wi-Fi connectivity and is making Newcrest’s safety and productivity systems more effective,” Telstra said, adding that fleet efficiency and real-time visibility have benefited from an 80% improvement in communications reliability on LTE-enabled assets.

The gold deposit at Lihir is within the Luise Caldera, an extinct volcanic crater that is geothermally active, and is one of the largest known gold deposits in the world, according to Newcrest. Most of the ore is refractory and is treated using pressure oxidation before the gold is recovered by a conventional leach process.

In the financial year ending June 30, 2018, Lihir produced 955,156 oz of gold. Since production commenced in 1997, the site has produced more than 10 Moz of the yellow metal.

Dr Jeannette McGill, Head of Telstra Mining Services, said Newcrest’s decision to invest in Private LTE technology further validates it as a dependable and scalable networking platform for the mining industry and one that enables mining houses to digitally transform.

“We’ve provided Newcrest with a tailored platform that will underpin its safety and digital mining ambitions and will help improve productivity and deliver new value and efficiencies to the business,” she said. “They’ll be using it to further modernise the mine site to enable the use of current and future mining applications, including tele-remote and autonomous systems, more extensively.”

The platform is completely independent from public mobile networks, according to Telstra, with Newcrest having been provided with its own dual-frequency base stations, LTE core and SIM cards, with the network’s configuration and coverage designed and implemented to meet the Lihir mine’s safety strategy and long-term mine plan.

Telstra Mining Services’ solution also includes ‘HetNet’ functionality that allows the Newcrest vehicle fleet to seamlessly switch between LTE and existing Wi-Fi networks without impacting critical mining applications.

Newcrest complemented the LTE technology solution by implementing new towers, data centres and redundant power systems across the site, according to Telstra.

McGill added: “Newcrest and Telstra Mining Services took what has become a best-in-class preliminary deployment approach with the network. Designing it for full production but initially deploying at two sites allowed Newcrest to validate the design principles, implementation techniques and practical capabilities of LTE before scaling their investment.”

Newcrest’s pragmatic approach, combined with flexibilities in the solution from Telstra Mining Services, enabled the desired outcomes and learning to be achieved within a relatively short timeframe, despite the remoteness of the Lihir operation, according to Telstra. Future phases of the project will further enhance coverage in-line with Lihir’s 20-year mine plan, and provide for expansion of coverage and capacity across the mine, processing plant, port and camp.

Chris Jordaan, General Manager, Newcrest Lihir, said: “The Lihir mine extends 300 m into a volcanic crater and our workers can often be exposed to elevated temperatures. Tele-remote and autonomous mining technologies are fundamental to working the hot work areas that will become more dominant features of our operation in the future.

“The Private LTE network will be a great enabler for these technologies and, coupled with the existing in-pit Wi-Fi network, we have been able to create a heterogeneous network that covers the whole mining lease.”

Gavin Wood, Chief Information & Digital Officer at Newcrest, said: “Safety is Newcrest’s number-one priority and the network Telstra Mining Services has built with us at Lihir will enable safer and more efficient mining using new technologies. The success of this project was 100% driven by leadership and personal commitment of the Lihir’s OT/IT team working together with Telstra Mining Services.”

LTE is a future-ready platform for wireless communications in mining, providing dependable and scalable communications that the next generation of machines, systems and workforce applications will require. Having been proven in carrier networks, it’s now seen as the mining industry’s next step for connectivity.
