Komatsu teams with Rio, BHP, Codelco and Boliden on zero-emission mining solutions

Working together to rapidly innovate in support of carbon reduction targets, Komatsu has teamed up with several of its customers to form the Komatsu Greenhouse Gas (GHG) Alliance.

The founding members of the alliance are Rio Tinto, BHP, Codelco and Boliden.

Through the alliance framework, Komatsu’s GHG partners will work directly with Komatsu to actively collaborate on product planning, development, testing and deployment of the next generation of zero-emission mining equipment and infrastructure, the OEM said. The alliance’s initial target is advancing Komatsu’s power-agnostic truck concept for a haulage vehicle that can run on a variety of power sources including diesel-electric, electric, trolley (wired), battery power and even hydrogen fuel cells.

“We are honoured that our customers, several of the largest mining companies in the world, have agreed to participate in the Komatsu GHG Alliance and work in partnership with us to develop sustainable solutions for mining,” Masayuki Moriyama, President of Komatsu’s Mining Business Division, said. “We look forward to close collaboration with these industry leaders to accelerate development and deployment of the next level of equipment designed to reduce greenhouse gases from mining operations and ultimately achieve the goal of zero-emission mining.”

The formation of the alliance brings together mining leaders willing to share time, resources and information to deliver zero-emissions equipment solutions, Komatsu said. The company intends to expand the alliance to additional mining companies to enhance industry-wide collaboration on solutions to decarbonisation.

In a separate release, Rio Tinto said it will conduct a pre-production trial of the new equipment at a site and has the option to purchase some of the first trucks from Komatsu once they are commercially viable.

Alf Barrios, Rio Tinto’s Chief Commercial Officer, said: “Rio Tinto and Komatsu have a shared history of partnership on innovation going back to when we built the world’s largest Komatsu autonomous haulage fleet in 2008.

“Our support of a trial, and the option to buy some of the first trucks from Komatsu, underscores our shared commitment to actively collaborate on product planning, development, testing and deployment of the next generation of zero-emission mining equipment and infrastructure as we look to decarbonise our business.”

As a company, Komatsu, meanwhile, says it is committed to minimising environmental impact through its business, targeting a 50% reduction in CO2 emissions from use of its products and production of its equipment by 2030 (compared with 2010 levels) and a challenge target of achieving carbon neutrality by 2050.

Komatsu has worked to reduce greenhouse gas emissions for customers through product development for decades in many areas including electric diesel dump trucks, electric power shovels, regenerative energy storage capabilities and fuel saver programs, it said.

The company’s initial concept for a haulage vehicle that can run on a variety of power sources, part of the power-agnostic development, is set to make its official debut at MINExpo 2021 on September 13-15 in Las Vegas, USA.

Aramine launches diesel-electric drill for narrow vein mining

Aramine has looked to complete its equipment range for narrow vein mines with the introduction of its diesel-electric hybrid miniDriller DM901 HDE drill rig.

The compact machine uses the diesel engine for tramming and electric motor for drilling, according to Aramine, while it can be operated tele-remotely, removing the operator from potential hazards.

The DM901 HDE has a low centre of gravity for optimal stability. Despite its narrow width, the two front stabilisers offer perfect drilling conditions, according to the company. This allows for both face and vertical drilling, Aramine said.

Aramine says the DM901 HDE only requires a 400 V electric connection and a water supply to operate and is designed with modular elements for easy assembly/disassembly in a mine. It “sneaks wherever our L130 and L150 miniLoaders go”, Aramine said. This means the new machine is ideal for sections between 6 sq.m and 12 sq.m.

With an existing partnership between Aramine and Epiroc, the company can offer an exclusive optional version with an Epiroc Feed and Drifter, Aramine said.

“As most of Aramine machines are, the DM901 HDE complements perfectly the Epiroc range,” Arnaud Paul, Aramine Equipment Sales Director, said.

Aramine says it is preparing its fully-electric battery-powered version for 2020, with innovations at all levels of the machine.
