Barminco set for Normet battery-electric Charmec trial at IGO’s Nova operation

Normet’s Charmec MC 605 VE Smart Drive battery-powered emulsion charger is continuing its tour of Australia, with Barminco signing up to trial the machine for three months at the Independence Group-owned Nova nickel-copper-cobalt underground mine in Western Australia.

Barminco, a Perenti company, says the trial is part of its commitment to improving performance and driving sustainability initiatives across its business. It represents the contractor’s first heavy-duty battery electric vehicle (BEV) trial, coming on top of the short trial it conducted with Safescape’s Bortana light electric vehicle, also at Nova.

The MC605 VE Smart Drive will be a direct replacement for the diesel-powered MC605 D Barminco uses at its underground client sites, with the battery-electric trial likely involving a mix of production and development operations.

“Along with the maintenance and cost benefits of using battery-electric equipment underground, it will also provide an improved work environment for our people,” Barminco said.

OZ Minerals, in October, became the first miner in Australia to take delivery of a battery-powered Normet Charmec MC 605 VE SD. The charging unit, which arrived at the Carrapateena copper-gold mine in South Australia, was also put through a three-month trial.

The work at Carrapateena involved the charging of 30 faces – all of which were charged without any major problems – with tramming times of 5-15 minutes and tramming distances of 1-3.5 km from the explosives warehouse to the face and back, according to Normet. The process saw 4.5 m long cuts and an average of 65 holes, with 300-400 kg of emulsion loaded per cut.

The trial involved the use of an on-board 1.5 t Emulsion Charging Module system provided by Normet and the application of Downer Blasting Services’ HEAT® 9000 ammonium nitrate emulsion.

The unit carried out charging with and without a trailing cable plugged into the mine site’s electricity infrastructure and a SmartDrive CT40 DC-charging trolley was also employed.

Reflecting on the Carrapateena trial, Normet said: “SmartDrive battery-electric vehicle architecture proved its ability for emulsion charging as this process is extremely energy efficient and enables independent operations even without a trailing cable plugged in.

“Silent slope performance as well as exhaust-, heat- and noise-free charging operations made a real impression on all users of the SD Charmec.”

Back in 2019, Normet made history with the MC 605 VE Smart Drive by demonstrating battery-electric emulsion charging in an underground production environment for the first time in Europe at the Pyhäsalmi mine, in Finland.

OZ Minerals on the road to electrifying Carrapateena mine

OZ Minerals’ electrification transformation at its Carrapateena copper-gold operation in South Australia has kicked into another gear with a Zero Automotive ZED70 battery-electric light vehicle arriving on site.

The company has made its electrification and sustainability aspirations clear to stakeholders, confirming it is working towards emitting zero Scope 1 emissions and striving to systemically reduce Scope 2 & 3 emissions across its value chain. It also wants to consume and produce in a way that generates zero net waste and creates value for its stakeholders.

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

The precursor to the ZED70 Ti electric light vehicle developed in partnership with Zero Automotive, the ZED70 (pictured) is based on a Toyota Landcruiser 79 Series and uses either NCM (Nickel Cobalt Manganese) or LTO (Lithium Titanate Oxide) battery chemistry.

The vehicle comes with continuous power of 75 kW and peak power of 134 kW, plus 358 Nm of continuous torque. Depending on the selected battery chemistry, the battery capacity comes in at 88 kWh (NCM) or 60 kWh (LTO).

The ZED70 Ti electric light vehicle to be delivered to Carrapateena following the trial of the ZED70 will use LTO chemistry and come equipped with a specially selected battery housing, control systems and charging capability to endure the “hyper saline underground environment” at Carrapateena.

“Working in partnership with Zero Automotive, we recently welcomed the first electric light vehicles onto site, and have the ZED70 Ti model in use underground,” Oliver Glockner, the OZ Minerals lead in developing the ZED70 Ti with Zero Automotive, said. “This is has been well received on site as a significant step in our electrification roadmap towards no diesel particulates underground and no scope 1 emissions on site.”

Dan Taylor, Business Development Manager at Zero Automotive, told IM that OZ Minerals has worked closely with the company in finalising the vehicle requirements and the change management process for implementing a battery-electric vehicle at the mine site.

“Some of the things I am talking about here include:

  • “Regular communications with their team on the progress with the project;
  • “Establishing charging points at the mine;
  • “Organising trial test drive bookings with those employees interested, and collecting performance data and feedback from them;
  • “Testing charging of the vehicle from one of their generators;
  • “Reviews by the emergency services and maintenance teams; and
  • “Planning the site acceptance testing when the OZ Minerals vehicle is delivered.”

Taylor said the LTO batteries the ZED70 Ti is fitted with can travel around 3 million km or endure 20,000 recharges before the battery re-charge ability reduces by 20%. This compares favourably with the 475,000 km, or 1,200 charges, it would take for the NCM battery’s re-charging ability to drop by the same amount.

At the same time as this, the LTO battery system will charge to a 95% charge in three hours on 415 V three-phase power, compared with four-and-a-half hours for the NCM equivalent.

“With DC-DC fast charging you will need 30 mins on the LTO (two hrs for NCM),” Taylor added.

Such benefits outweigh the lower energy density and upfront expense that come with using these LTO batteries, according to Taylor.

In October, OZ Minerals became the first miner in Australia to take delivery of a battery-powered Normet Charmec MC 605 VE SmartDrive (SD) at Carrapateena.

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.

Normet gears up for fully-electric and diesel-powered machine growth

As Normet continues its new technology push, it has decided to invest in its lisalmi facility in Finland, the company’s core production and research and development site.

The company will put €3 million-5 million ($3.35 million-5.58 million) into building a new digital testing centre, expanding the production capability and investing in production automation, it said. The target is to improve productivity in lisalmi to ensure both competitiveness and to have manufacturing capacity to support business growth.

The announcement came shortly after Normet launched a fully-electric offering for mining and tunnelling construction at the recent Bauma fair in Munich, earlier this month.

Its SmartDrive technology is a sophisticated and fully-engineered battery-electric architecture able to operate underground totally emission-free, saving costs at the same time, it says.

The company also used the event to showcase its SmartScan 3D laser scanning technology to validate the spraying quality and SmartSpray, the next step towards fully-automated concrete spraying technology, according to Normet.

In the latest lisalmi announcement, Normet said it expected the demand for both for fully-electric and diesel-powered machines to grow, hence its planned investment.

Kari Hämäläinen, SVP Equipment Business Line, Normet, said: “lisalmi is the core production and research and development site for us. We want to ensure we have the best technology capabilities to meet the demand of future. Streamlining the manufacturing process and increasing productivity is also critical to ensure our competitiveness going forward.”
