BHP to trial Epiroc Boomer M2 battery-electric jumbo at Olympic Dam mine

BHP has unveiled a battery-electric Epiroc Boomer M2 jumbo at its Olympic Dam mine in South Australia to help support the company’s target to reduce operational greenhouse gas (GHG) emissions, including by minimising reliance on diesel.

The 28.7-t, 14.5-m long battery-electric rig will be powered by a 150 kW traction motor and 150 kW battery system, eliminating greenhouse gas emissions from diesel-powered tramming. It will be tested for efficiency, productivity and comfort over the 12-month trial period, BHP said.

Jumbos are used in underground mining development to drill holes, which are then loaded with explosives and open up new areas. Post-blasting, jumbos install large bolts to stabilise mine walls. BHP currently operates 16 Epiroc jumbos at Olympic Dam.

The fully-electric machine will also break new ground in its user experience by reducing noise and vibration, and eliminating heat and the emissions of diesel particulate matter, the miner said.

Andrew Harris, General Manager Olympic Dam Mine, said: “The world is going to need a lot more of South Australia’s high-quality copper, and the team at Olympic Dam is behind our push to produce that copper more sustainably.

“Collaboration with supply partners like Epiroc will be critical to developing the technology required to reduce emissions, while ensuring we continue to improve the safety and productivity of our operations. I can’t wait to see what this new fully-electric jumbo can do.”

BHP’s Group Procurement Officer, James Agar, said: “The fully-electric jumbo is yet another innovation that will support our progress towards achieving our medium-term target of reducing operational greenhouse gas emissions by 30% by financial year 2030.”

Alisa Bennett, Underground Business Manager for Epiroc Australia and Mongolia, said: “Epiroc are excited to partner with BHP in a new era of electrification in Australia. Epiroc’s ambitious sustainability targets like halved carbon emissions by 2030 matches BHP’s sustainability agenda well. The Boomer M2 Battery rig will facilitate a healthier and safer underground working environment for our customers without compromising on productivity.”

BHP has a medium-term target to reduce operational GHG gas emissions by at least 30% by the 2030 fincial year, from a financial year 2020 baseline. Approximately 40% of BHP’s operational emissions in its baseline year came from diesel-powered vehicles.

The trial of the jumbo also supports BHP’s efforts to minimise the operational impact of diesel particulate matter in underground mining operations by 2025, as part of BHP’s participation in the International Council on Mining and Metals’ Innovation for Cleaner, Safer Vehicles initiative.

The fully-electric jumbo trial builds on electric vehicle initiatives at Nickel West in Western Australia, Olympic Dam in South Australia and BMA’s Broadmeadow mine in Queensland. BHP is also collaborating with Caterpillar Inc and Komatsu to develop zero-emissions electrified haul trucks, and battery-electric locomotives with Wabtec Corporation and Progress Rail.

BHP has also signed Power Purchase Agreements to source renewable power for a number of its operations in Chile, Queensland, South Australia (with Iberdrola and Neoen) and Western Australia. BHP also has customer decarbonisation partnerships with steelmakers in China, Japan, Korea, India and Europe, which collectively represent around 17% of reported global steel production capacity.

Epiroc and Orica announce world first semi-automated explosives delivery system

Orica and Epiroc Rock Drills say they have successfully co-developed a prototype of the world’s first semi-automated explosives delivery system.

A sought-after technology by customers in the underground hard-rock mining sector, Avatel™ will deliver a completely new way of approaching development blasting operations by eliminating charge crew exposure at the face, according to the companies.

Orica and Epiroc expect to commence commissioning on Avatel, the first-of-its-kind, industry-driven explosives delivery system, in the coming weeks, meaning the solution could be deployed at underground mine sites as early as the end of 2021.

The solution provides safe access for an operator in cab to execute the development cycle while reducing the reliance on costly, time-consuming and, at times, ineffective controls put in place to manage the risks to personnel working in one of the highest risk areas of an underground mine, the companies said.

Orica’s Chief Commercial and Technology Officer, Angus Melbourne, said: “The mining industry is moving rapidly toward a digitally integrated and automated future, and Avatel will fulfil our shared vision of developing safer and more productive blasting solutions.

“Achieving this significant development milestone, despite COVID-19 disruptions, shows the strength of our collaboration with Epiroc and our collective ability to deliver the future of mining.”

Epiroc’s President Underground division, Sami Niiranen, said: “With this partnership, we continue to raise the safety bar by combining world leading technologies that will make a difference in underground mines.

“The Avatel prototype represents the first step towards autonomous charging – a vital step in the journey toward safer and more productive blasting operations underground. We are looking forward to bringing this ground-breaking solution to customers worldwide.”

A key enabling technology of Avatel and Orica’s automation vision is WebGen™, Orica’s fully wireless initiation system. When combined with Orica’s LOADPlus™ smart control system, specifically designed on-board storage, assembly, digital encoding capability and Subtek™ Control bulk emulsion, Avatel provides customers with complete and repeatable control over blast energy from design through to execution, the companies say.

Built on the foundation of Epiroc’s Boomer M2 carrier, and integrated with Orica’s latest explosives technology, Avatel is a twin boom, semi-autonomous and fully mechanised development charging solution that, Epiroc and Orica says, allows a single operator to complete the entire charging cycle from the safety of Epiroc’s enclosed ROPS and FOPS certified cabin.

“Avatel is equipped with the most sophisticated version of Epiroc’s acclaimed Rig Control System (version 5),” they said.

“Through its intuitive interface, with a large touchscreen and dual multifunctional joysticks, and, combined with Epiroc´s computer assisted boom positioning features, it can be easily handled. Integrated with Orica’s LOADPlus, charge plans and other important data will be communicated between the systems.”

The design of Avatel builds on Epiroc’s application design experience, further adapted to match conditions this new solution will face. Future developments can be extended to other Epiroc carriers including battery drivelines, they say.

Other advantages include flexibility at the face through Epiroc´s dual diesel/electric plug-in power solution.

“The convergence of these technologies ultimately ensures that the right explosives will be safely delivered into the right holes and given the right timing to achieve optimal efficiencies and the desired outcomes,” the companies said.

Extensive trials of Avatel will take place throughout 2021, before the first commercially available systems are expected to enter service.

Orica announced in November 2019 that it had entered a partnership with Epiroc to develop a semi-automated explosives delivery system.
