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.

Normet battery-powered Charmec arrives at OZ Minerals’ Carrapateena mine

OZ Minerals has become the first miner in Australia to take delivery of a battery-powered Normet Charmec MC 605 VE SmartDrive (SD), with the unit arriving at its Carrapateena copper-gold mine in South Australia last month.

In a post on LinkedIn, the company said of the machine: “It is Australia’s first battery-powered vehicle for underground explosive charging and emits zero local emissions.”

Back in June 2019, Normet made history by, for the first time in Europe, demonstrating battery-electric emulsion charging in a production environment underground at the Pyhäsalmi mine, in Finland, with its Charmec MC 605 VE SD.

This followed the launch of its SmartDrive battery-electric vehicle architecture at Bauma in Munich, back in April 2019.

According to Normet, battery-based charging makes the explosives charging process safer and more efficient, as there is no need to plug in to the mine’s electric grid.

The company says the Charmec MC 605 VE SD presents the new era of charging in underground mines.

“Normet SmartDrive battery-electric vehicle technology, integrated to the state-of-art emulsion charging technology, offers the highest value to customer in terms of safety, health, ergonomics and productivity, with zero local emissions,” it said.

A prefeasibility study on an expansion of Carrapateena, released in June, included a trial of electric light vehicles and establishment of a renewable energy hub.
