RCT says it has partnered with Northern Star Mining Services (NSMS) to implement a digital autonomous mining fleet at the Ramone gold mine in Western Australia.

The Ramone mine, near Wiluna, is owned by Northern Star Resources, the parent company of NSMS. It is 35 km southeast of the Jundee Gold Mine, which Northern Star also owns.

The technology has significantly advanced autonomous fleet production activities and sets the underground operation on a pathway to full mine digitisation, according to RCT, which is now owned by Epiroc.

The rollout represents the latest in a long line of successful projects that has seen RCT automate NSMS’s underground mining fleets across the Kalgoorlie and Yandal regions.

At Ramone, machine operators will use RCT’s ControlMaster® Automation Centre and supervise two Sandvik LH517i underground loaders commissioned with the latest ControlMaster digital solution.

The technology significantly enhances production by enabling faster autonomous loader cycles and greatly reduces maintenance downtime associated with machine damage, RCT said.

Once RCT’s ControlMaster Automation Centre is relocated from underground to the surface on site, it will allow for fast “hot seating” and enable site managers to capture the time previously lost over the shift changes and continue production cycles during firing activities, it added.

The NSMS team at Ramone is benefitting from the rollout of RCT Connect, the only mine site communications network designed to accommodate autonomous mobile machine fleets, according to RCT.

RCT Account Manager, Scott Phillips, said: “Our digital automation technology will provide the Ramone operation with every advantage to mine safely, efficiently and continue to make solid advancements for years to come. Northern Star Mining Services’ investment in our specialised communications technology provides a strong foundation from which to grow autonomous operations as the mine evolves and site needs change.

“Our experienced Goldfields team has worked very closely with the Ramone site team to ensure this initial rollout goes smoothly and we are very pleased with the successful outcome.

“This is just the first chapter in what we hope will be a long and very productive working relationship between RCT and the Northern Star Mining Services crew at Ramone.”

RCT’s latest partnership with Gold Fields in Australia has seen, it says, the transformation of the Granny Smith mine and machine fleet into a state-of-the-art, digitally connected powerhouse.

The project, which RCT says embodies the mining company’s key value of innovation, is designed to increase productivity.

Gold Fields’ Granny Smith mine is no stranger to RCT, having been one of its technology partners for more than 20 years.

This latest project has seen the Eastern Goldfields underground gold operation become one of the most innovative, digitally-connected mines in the world, according to RCT. The project saw its Kalgoorlie-based team of innovative technicians upgrade the site’s six existing Caterpillar loaders from analogue to digital.

This required the Kalgoorlie branch team to design and build specialised mounts and overhaul the site’s existing cabins. In addition, a total of 11 Area Access Controls (AAC) were also converted from analogue to digital to facilitate the upgrade.

“We recognise that they made a significant investment into the original technology, and we wanted to find the most cost-effective and sustainable solution available,” RCT’s Kalgoorlie Branch Manager, Rick Radcliffe, said.

The team converted three of the site’s existing analogue TeleCabins and transformed them into digital ControlMaster® Automation Centres for underground use and two surface Automation Centres to digital, bringing them into the future.

The site chose to use RCT’s own full-scale digital communications solution – RCT Connect – to meet the demands of autonomous machines across the mine site. The technology will cater to Granny Smith’s current and future machines, according to RCT.

The Kalgoorlie branch finished the upgrades in December last year, and although the technology has only been in place for a few months, the site has experienced amazing results from day one, according to the company.

Granny Smith Mine Manager, Michael Place, said: “The ability for the operators to mine from the surface with a pristine picture/video thanks to the digital network has meant they have been able to increase the number of buckets per shift, while adding to the comfort of the operators.

“Implementing the new digital infrastructure RCT Connect has significantly improved both the availability and reliability of Granny Smith’s semi-autonomous remote production loaders and stoping fronts to date.”

The upgrade saw the popular analogue technology that uses the Yagi antenna replaced with RCT Connect.

Radcliffe added: “While the Yagi’s have been a tried and tested technology for many years, our digital RCT Connect Access Points has taken the Control Master underground communications system to another level. The system is now more reliable and provides a clearer picture and improved operator visibility.

“The feedback we have received from site is that the operators love the new technology and they wished they implemented it ages ago.”

As well as experiencing the significant benefits of digital technology today, Granny Smith is futureproofing its operations, allowing it to make small, incremental changes as and when they are ready, RCT said.

RCT Connect, RCT says, is a plug-and-play system, making it easy to install and maintain. The technology has produced a clearer picture, which has greatly assisted Granny Smith personnel to continue operating their machines safely in high-risk locations.

Radcliffe concluded: “Another added benefit to moving to digital is that RCT can now remotely support our clients to a higher level and are able to monitor and complete repairs in a short timeframe, as it eliminates the need for a technician to travel to site to troubleshoot in many cases.”

RCT to equip Develop with autonomous loading options at Bellevue gold project

RCT says it is partnering with mining services company Develop to deploy state-of-the-art digital automation technology at its recently-awarded Bellevue gold operation in Western Australia.

RCT’s digital ControlMaster® solution will empower Develop with the best autonomous technology to safely manage its underground mobile equipment fleet and make consistent production gains, according to the company.

Develop was awarded work valued at around A$400 million ($280 million) at Bellevue Gold’s Bellevue Gold Mine in Western Australia back in April. The contract, which covers a period of almost four years, provides for Develop’s Underground Services division to undertake construction, development and production activities at the underground mine.

The autonomous solutions are in line with Develop’s innovative business ethos of combining impressive technology with experienced professionals to transform operations into mining powerhouses, RCT said. This will see operators use the ControlMaster Automation Centre and manage a Sandvik LH517i underground loader within the underground complex.

In the future the company will roll out additional autonomous Sandvik LH517i loaders in line with its evolving mining fleet requirements as it moves into production activities.

To accommodate a larger autonomous fleet, Develop will harness the power of ControlMaster Multi-Machine Select (MMS) and Multi-Machine Control (MMC) capabilities into its Automation Centre, RCT says.

These features mean machine operators can switch between underground loaders located throughout the mine and subsequently take control of each machine.

Develop will further support the Bellevue fleet by rolling out RCT Connect, which, RCT says, is the only available mining communications infrastructure designed to accommodate autonomous mining equipment.

The specialised Wi-Fi network will ensure consistent communications and very low machine latency between the machine fleet and Automation Centre, according to RCT.

RCT’s Kalgoorlie Branch Manager, Rick Radcliffe, said the work at Bellevue will provide a strong foundation on which to grow a business relationship between the two companies.

“We are very pleased to be Develop’s automation technology supplier and provide cutting-edge solutions and a very high level of service from the beginning at Bellevue,” he said. “We will be there alongside Develop as they kick off autonomous machine activities and we are confident that our technology will deliver results every shift.

“RCT proudly has 50 years of experience supporting Goldfield’s mining companies and we look forward to applying all our knowledge to whatever situation Develop faces in the future.”

RCT’s autonomous mining equipment-specific Wi-Fi hits its stride

RCT says its new specialised Wi-Fi network for autonomous mining equipment is generating strong and positive feedback from industry.

The first ever mining communications system created specifically to support all underground autonomous mining equipment, RCT Connect is flexible in that it is designed to engage with any third-party systems and can enhance the performance of any mining automation and control solutions available on the market, according to RCT.

Since the network’s launch in 2019, it has been deployed at multiple active mines around the world – including Kazzinc’s Tishinsky mine, in Kazakhstan – and has generated strong and positive feedback from site personnel, RCT says.

Brendon Cullen, RCT Automation and Control Product Manager, says RCT Connect is the best underground communications network option available.

“The system is inexpensive and very user friendly so it can be set up quite easily by mine site technicians who do not need specialised training in order to establish and maintain this technology,” he said.

“RCT Connect is designed to be agnostic, and so can integrate with all of the commercially available automation and control solutions offered by global manufacturers.”

He added: “The network is designed to deliver very stable performance and low, consistent latency between operator stations in secure, remote locations and the machine located in production areas.”

Customers will be able to cheaply scale RCT Connect to suit their needs as underground mining operation evolves, according to the company. The network can be adjusted to suit various tramming distances and can ensure effective machine operation over shorter – as well as longer – runs.

Cullen said one key aspect of RCT Connect is its smart roaming feature, which means it is always searching for new wireless access points as underground mining equipment auto trams between certain locations.

“Many commercially available communications networks are configured to access certain nodes for too long and as mobile mining equipment continues to traverse a site, it can result in communication failures,” he said.

RCT says it has released the first digital Wi-Fi communications network designed specifically for machine automation and control in underground mining operations.

RCT Connect is designed to be user friendly and portable and can be installed into a production area and commissioned with minimal time and expertise, according to the automation leader.

The company has already made significant headway with RCT Connect, with the network having been tested at a mine site in Western Australia and recently deployed in an underground mining operation outside of Australia.

RCT Connect has been built to withstand the harsh conditions, common in underground mining environments, and can operate in temperatures ranging from -20°C (-4°F) to 60°C (140°F), RCT said.

It uses a coaxial cable able to transfer power and information to access points for up to 1.5 km before additional power insertion is required along the length of a drive, according to RCT.

“This feature offers several major benefits over traditional Wi-Fi deployments such as reduced requirement for configuration, eliminating costly cables to run between access points and a simple installation with only two connections,” the company said.

Once operational, RCT Connect provides a simple connection to a ControlMaster® Area Access Control at strategic locations which then links into the mine-wide communications backbone to transfer information to a machine operator located in a ControlMaster Automation Centre on the mine’s surface, the company said.

The platform operates at 2.4 GHz and is capable of carrying out remote diagnostics, live machine tracking and delivering live health and production data from the machine, according to RCT.

RCT Product Manager Automation & Control, Brendon Cullen, said RCT Connect offers several distinct advantages over commercially available digital communication networks.

“RCT Connect is specifically designed to ensure uninterrupted communication between the machine and the operator regardless of location,” he said.

“The platform has very stable performance with low, consistent latency and so ensures reliable communications between command inputs from the surface station and subsequent machine activities.”

He added: “We have also optimised the platform to enable smart roaming and, therefore, seamless handover between wireless access points so that there is no dropout along the length of the drives.”

In other commercially available communications networks, node handover is configured differently so if the machine is looking for a node or hangs on too long then communication failures arise, Cullen explained.

RCT Connect can be sold as a standalone package or in conjunction with RCT’s ControlMaster automation products.
