Evolution Mining’s efforts to achieve net zero emissions by 2050 are already being witnessed at its Red Lake Operation (RLO) in Canada, where the company is pursuing fleet replacement and energy efficiency gains through deepening its partnerships with Epiroc and Rokion.

The pacts with the two battery-electric vehicle (BEV) service providers also extend to operational changes Evolution is making via fan timers for underground ventilation at RLO.

In partnership with Epiroc, Red Lake has taken the opportunity to leverage its offering of conversion kits to transform diesel-powered loaders easily and seamlessly to battery-electric driven operation, it said. RLO has ordered two of the converted diesel-powered Scooptram ST1030 machines for deployment underground with the first one delivered at the start of December 2021. The site has also ordered two Scooptram ST14 battery-electric loaders that are designed based on the diesel ST14 version, which are scheduled for delivery in 2022. This order was announced last year by Epiroc.

The Red Lake team has also purchased three Rokion electric light vehicles – two R100s and an R400. They have been risk assessed in the field, have dedicated charge stations and are capable of online data capture and storage, the company said.

Rokion says the R100 series includes a four-passenger crew truck and a two-passenger utility truck, with both models built on the same frame dimensions and available in ramp-ready configurations. The R400 platform, meanwhile, is able to accommodate three passengers in a utility vehicle setup or up to 12 in a passenger crew variant.

“The electric fleet brings the opportunity to save on maintenance, cooling and ventilation costs with reducing expenditures related to diesel and power usage,” Evolution Mining says.

“This cost saving and energy efficiency has similarly been seen in the recent changes to the underground ventilation fan timers, which are vital in clearing the drives, post blasting of headings. After assessing the timer programming, the functionality of the fan timer switch was altered so that operators can run them when needed rather than running automatically at irrelevant times.”

Epiroc to supply equipment, services for Codelco’s Chuquicamata underground mine

Epiroc is to deliver underground loaders, face drill rigs, rock bolting rigs and mine trucks to the Chuquicamata underground mine in northern Chile following an order from Codelco.

The large equipment order, which comes on top of the signing of a large contract for services at Codelco’s Andina mine and a large order for equipment used at its El Teniente mine, also includes several years of technical support and training. The order is valued at more than $20 million and was booked in April 2020.

Codelco, the world’s largest copper producer, opened the Chuquicamata underground mine in 2019 as it looked to transition the world’s largest open-pit mine into a technologically advanced underground operation. The transformation will extend the mine life by 40 years, according to Codelco.

Helena Hedblom, Epiroc’s President and CEO, said the company was proud to be a key partner of Codelco “as it significantly extends the life of the Chuquicamata mine in the most productive, efficient and safe manner possible”.

Juan Mariscal, Sourcing Category Manager at Codelco, says: “Epiroc was chosen because it complied with all the technical, safety and performance requirements that Codelco demanded for the Chuquicamata Underground Mine project, while being the supplier that provided the best economic proposal for all its equipment as a whole.”

The order includes multiple units of the Scooptram ST1030 and ST18 loader, the Boomer S2 face drilling rig, the Boltec M bolting machine, and the Minetruck MT65 (pictured), the highest payload capacity underground truck in the world.

The machines will be equipped with 6th Sense solutions for automation, connectivity and information management, Epiroc says. The solutions include Epiroc’s Rig Control System, RCS, which makes the equipment ready for automation and remote control, and Epiroc’s Certiq system, which allows for intelligent monitoring of machine performance and productivity in real-time.

Delivery of the equipment will take place later this year.
