Ausdrill is bringing One Touch drilling to its Rock Commander blasthole fleet, in the process creating a future where drilling can be optimised for efficiency and precision with minimal manual intervention.

The company, part of Perenti, said the innovative technology is set to transform the way it drills, and the way its operators work.

With just a single touch of a button, a driller can pre-select the hole depth and the machine takes care of the rest. It will touch ground, collar the hole, and then drill down to the required depth, including changing rods and flushing the hole. This means there is no need for manual intervention except for potential finetuning, Ausdrill says.

“One Touch ensures every step is meticulously executed, prolonging component life and reducing wear and tear, making it a safe, highly efficient and cost-saving solution,” it added.

In a video promoting the launch, Luke Phillips, Area Manager, Drill & Blast Operations, said One Touch drilling sets Ausdrill apart from its competition: “We are bringing this technology that is essentially already existing in the marketplace to the world-class Rock Commander fleet.”

The move coincides with the recently awarded five-year contract at the Northern Star Resources-owned Kalgoorlie Consolidated Gold Mines (KCGM) Fimiston open-pit gold mine in Kalgoorlie, Western Australia.

The circa-A$160 million ($104 million), 60-month contract – the largest ever Australia surface mining contract Perenti has received – incorporates activities that commenced March 1, 2022, and will continue to March 2027. It includes the provision for up to 14 production blasthole drill rigs to support ongoing operations.

Phillips said One Touch drilling and the KCGM contract form an integral part of the Ausdrill technology roadmap.

“The stages thereafter will be a semi-autonomous approach to how we work, and mine and drill in and around underground work,” he said.

Ian Chisholm, a Driller at the Fimiston Open Pit, referred to the technology as “cruise control” for a drill rig.

“You just push the button and everything is done for you,” he said, adding that the rest of the process is made up of monitoring tasks.

Phillips added: “One Touch drilling benefits the client because it has the potential to remove human error in regards to rework or redrilling holes. [It also] reduces or removes damage because it is a semi-autonomous product, and it’s something that our trainees can engage with at an early grassroots stage.”

Related to this, SITECH WA, a provider of innovative technology solutions for mining operations in Western Australia, recently announced a strategic partnership with Ausdrill to introduce Trimble Groundworks machine guidance technology across Ausdrill’s Rock Commander fleet.

The integration was referred to as a milestone achievement for both companies, with the successful implementation of Groundworks on Rock Commanders at BHP WAIO laying the foundation for this partnership. The synergy between Rock Commander and Groundworks has solidified this decision, further influencing its adoption at KCGM’s Fimiston gold open pit (the Super Pit).

Trimble Groundworks boasts a user-friendly interface that enhances job site safety, accuracy and operational efficiency, according to the company. Operators of all skill levels can quickly adapt to and leverage the system’s capabilities, making it a powerful tool for mining professionals. Real-time spatial information provided by Groundworks also significantly enhances safety by alerting operators to exclusion zones and potential hazards.

One of the notable benefits of this integration is the elimination of the need for manual marking of drill patterns, resulting in substantial labour cost savings, the companies said.

Exyn Technologies providing speed and safety benefits for mine surveyors

Exyn Technologies says it is helping mines all over the world to become safer and more efficient with the use of its products, reporting on a comparison study made at Northern Star Resources Limited’s Pogo Mine in Alaska that showed the ExynAero is not only more efficient and accurate at mapping difficult places, but that it is also safer for the surveyors involved.

In this study comparing ExynAero, a fully autonomous aerial robot, with traditional CMS methods, the report authors showcased a significant improvement in safety, survey quality and time savings.

Exyn’s fully autonomous robot pairs a rotating LiDAR unit with a flight platform in order to perform cavity mapping surveys within open stopes. This hardware, combined with what is now the highest level of aerial autonomy, Level 4A Autonomy (AL4), allows survey teams to map deeper, more accurately, safer, and faster than before.

Andrew Loomes, Chief Mine Surveyor, Pogo Mine, said: “It is infinitely safer to use…we’re nowhere near the brow now, doing jobs around the corner in some cases. The safety aspect is definitely one of the driving factors to why we purchased the gear.”

Using Exyn technology instead of traditional surveying methods is a very low risk alternative for both surveyors and equipment as it keeps both out of potentially dangerous and unknown situations, Exyn says.

“The quality is unmatched as the unique application of Level 4A Autonomy to pilot the unit doesn’t require line of sight. As a result they can prove areas are between 12-35% bigger than traditional methods because they lack the limitations of traditional methods and have greater capacity to detect things like gas pockets.”

Time wise, it is 45% quicker than traditional methods requiring only 15 minutes compared with the 27.3 minutes taken by traditional CMS, the authors said.

Loomes added: “Even though [CMS] takes twice as long, from a quality standpoint, to get the same data from a CMS would take even longer with more equipment…the data doesn’t even compare.”

Australia-based gold miner Northern Star Resources has selected Sandvik Mining and Rock Solutions to supply 32 new pieces of mobile equipment for its Australian operations.

Northern Star operates several open-pit and underground mines across three gold production centres: Kalgoorlie and Yandal in Western Australia, and Pogo in Alaska, USA. The company will bolster its Sandvik fleet with 17 Toro™ TH663i underground trucks, 10 Toro LH621i underground loaders, four Toro LH517i underground loaders and a Sandvik DD422i development jumbo with dual control.

Loader and truck deliveries are planned to begin in September quarter 2023 and continue into June quarter 2025. The drill is scheduled to be delivered in the June quarter of 2024.

“This commitment underscores the partnership between Northern Star and Sandvik and reflects trust in our advanced, intelligent technology that helps make our customers more productive, more profitable and more sustainable,” Wayne Scrivens, Vice President, Sales Area Australia and New Zealand, Sandvik Mining and Rock Solutions, said.

The Toro TH663i trucks each have a 63 t carrying capacity and low overall equipment weight for high ramp speeds, Sandvik says. They come with Operator Speed Assist as a standard feature to automatically limit the top speed of the vehicle during level and downhill driving. The truck’s low weight, efficient engine technology and fast ramp speeds result in low fuel consumption per hauled tonne and overall reduction of CO2 emissions, according to the OEM.

The 17 t Toro LH517i loaders, Sandvik says, provide superior hydraulic power for fast bucket filling. A powerful drivetrain enables high-speed tramming and increased productivity, while long-life components, specifically developed for the rough underground environment, contribute to low cost per tonne.

The 21 t Toro LH621i loaders are engineered for rapid mine development and large-scale underground production. With superior hydraulic power for fast bucket filling and drivetrain power for high ramp speeds, this loader can quickly clear tunnel headings for rapid advance rates, according to the company.

Zenith Energy has converted the preliminary works agreement and term sheet it had in place with Northern Star Resources related to bolstering the power supply to the Jundee gold mine in Western Australia with a renewable energy Power Purchase Agreement.

Jundee is an existing mining operation that will have wind, solar and battery retrofitted into the mix and integrated into the existing gas power station. The renewable generation being added includes 24 MW of wind, 16.9 MWp of solar, and 12 MW/13.4 MWh of battery energy storage.

Zenith says this new energy mix will result in 56% of the mine site’s power coming from renewable sources, contributing towards the aim of cutting Jundee’s Scope 1 and 2 carbon emissions by 35-50% by 2030.

Currently all ore is sourced from Jundee underground operations which yield circa-1.8 Mt/y of ore. There are three underground portals which provide access to the various underground lode structures – Barton, Gateway and Invicta portals. Underground mining is being carried out by an up-hole long-hole open stoping sequence as its primary method. No backfill or paste is used.

The Jundee processing circuit is a conventional carbon-in-leach plant with a hard-rock processing capacity of approximately 3 Mt/y. The process consists of a single toggle overhead eccentric swing jaw crusher followed by a SAG and ball milling circuit incorporating gravity recovery and carbon-in-pulp process achieving 92% recoveries, according to Northern Star.

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.”
