Contract miner Byrnecut has taken the next step on its journey towards expanding its battery-electric equipment fleet with the roll-out of the Sandvik DD422iE development drill with dual controls at the BHP-owned Prominent Hill mine in South Australia.

The drill is the first battery-electric Sandvik development drill in operation in Australia.

Byrnecut took delivery of the battery electric jumbo at Prominent Hill copper mine in December 2023. The machine was put to work alongside Byrnecut’s existing fleet of diesel-powered equipment, including Sandvik development drills, production drills, cable bolters, trucks and loaders. Five months on, drill operators and Byrnecut management alike are impressed by the jumbo’s reliability and its contribution to a cleaner, quieter underground environment, Sandvik reports.

Technical Services Manager at Byrnecut, Dave Taylor, said th Sandvik DD422iE jumbo has “fitted in exactly” as a diesel-powered drill would have, working as it is designed to.

“It’s got all the pros that you would expect, just without all the fumes that come out of the diesel engine,” he added. “We always want to be at the forefront of technology and to look for ways to reduce emissions and diesel particulates – and this is one way of doing that.”

Taylor says the roll-out was simplified, as the Sandvik DD422iE charges by using the same electrical infrastructure used to power the rock drills on the diesel-powered jumbos. “The jumbos we currently have use their diesel engines to tram around but are plugged in and the rock drills run off thousand-volt power via a trailing cable,” he says. “There’s was no additional infrastructure because the DD422iE is charging using what’s already there in the diesel version.”

In a typical scenario, the Sandvik battery-electric jumbo will tram to the work site using electricity stored in its battery. While drilling is underway, the battery is recharged via the patented Sandvik Charging While Drilling technology, allowing the machine to tram away once the drilling cycle is completed.

General Manager for Byrnecut Australia, Craig Barendrecht, says the feedback he has received on the drill is positive despite some initial reservations. “It’s fitted in seamlessly and we’ve had no dramas with operating a battery drill amongst the standard diesel fleet.”

Barendrecht says with Byrnecut planning to increase their battery-electric equipment fleet, the performance of the jumbo is encouraging. “We’ve never previously seen a massive market for the battery jumbo because of the restrictions around tramming distances,” he says. “This is helping to dispel some of those preconceived concerns with how to actually fit an electric jumbo in amongst the traditional diesel fleet.

“This is just an incremental step in getting to that ultimate point where we run a full electric fleet of drills and loaders and trucks.”

Maintenance Superintendent, Mark Noden, says there was an initial learning curve around maintenance requirements for the battery electric rig. However, from an operator perspective it is simple to step from the diesel model to the electric. “I have had no complaints and the support from Sandvik is always good,” he says.

Nathan Cunningham, Business Line Manager for Underground Drills at Sandvik Mining and Rock Solutions, says Byrnecut has consistently demonstrated that it is a forward-thinking mining business, and the purchase of the Sandvik DD422iE reinforces this. “Byrnecut’s trust in the Sandvik product has paid off with the rig operating exactly as it was expected to.”

Australia’s first fully-automated, battery-electric Sandvik DL422iE drill goes to work at IGO Nova

IGO and Barminco have put Sandvik’s DL422iE longhole drill to work at the Nova operation in Western Australia, becoming the first mine in Australia to roll out the fully-automated, battery-electric rig.

The nickel-copper-cobalt mine, in the Fraser Range, is owned by IGO and operated by Barminco. Both companies have been trailblazers in terms of trialling electrified mining technologies and, like Sandvik Mining and Rock Solutions, they are a part of the Electric Mine Consortium.

Barminco purchased the Sandvik DL422iE, which was commissioned and put to work in July.

Darren Kwok, Head of Mining Electrification and Technology at Barminco, said: “Accelerating decarbonisation is one of our sustainability priorities and there are clear benefits to using battery-electric vehicles in the underground environment. Reducing or eliminating diesel emissions improves working conditions for our people and also has the potential to improve efficiency and profitability. We’re very excited to see the benefits that this new Sandvik rig can provide.”

Chris Carr, Head of Technical Services and Acting General Manager Nova at IGO, added: “At IGO, we believe in a clean energy future, and that extends to our underground mining operations where the electrification of our fleets will create a safer, greener and more productive operation. The arrival of the new Sandvik drill is an important step towards our commitment to be net zero across our direct operations and projects by 2035, if not sooner.”

The Sandvik DL422iE is a fully-automated, battery-powered top hammer longhole drill designed for underground mass mining in 4 x 4 m or larger production drifts, Sandvik says. It can drill vertical and inclined fans and single or parallel Ø89-127 mm longholes up to 54 m in depth using ST58 and ST68 tube rods.

The drill’s electric driveline includes a battery package and electric motor to allow for zero emissions while tramming and also reduced thermal load. The DL422iE also features Sandvik’s patented Charging While Drilling technology; an innovation for reduced battery charging time without the need for additional infrastructure.

Nathan Cunningham, Business Line Manager at Sandvik Mining and Rock Solutions, said: “We’re seeing considerable customer interest in Sandvik battery-electric vehicle solutions that help remove diesel from underground mines. If a miner is able to achieve a fully-electric underground operation there can a be a flow-on effect for the ventilation capacity calculations. For new mines, in particular, this can reduce bring a double benefit – better worker health and a reduction in the work required to meet ventilation requirements.”

The DL422iE is part of the Sandvik 400iE series of drill rigs that, together, provide a battery-electric solution to just about every underground challenge.

“Other members of the family include the Sandvik DD422iE mining and tunnelling jumbo and the Sandvik DS412iE rock bolter,” Cunningham says. “The DD422iE was launched in 2016 and has since logged more than 4 million metres of drilled holes and over 18,000 kilometres of tramming with zero emissions. Meanwhile, the DS412iE rock bolter was launched in 2021 and is rapidly transforming mines across the world.”

Kwok added: “Electrification/decarbonisation is a key priority for Barminco and one of the most important trends in the sector at the moment, alongside automation. For this reason, we’re delighted to have Sandvik as a technology partner who is providing industry-leading solutions to the challenges we face.”

Fully owned by IGO, the Nova Operation uses long hole and sub-level open stoping with paste backfill. In thr 2022 financial year, it achieved total production of 26,675 t of nickel, 11,483 t of copper, and 982 t of cobalt.
