BluVein XL open-pit mining dynamic charging solution gains momentum

Much of the buzz around BluVein to this point has focused on its dynamic charging infrastructure for underground mining and quarries, but the company has also been gaining momentum around a surface mining project – as the most recent Charge On™ Innovation Challenge announcement indicates.

The company and its BluVein XL solution were today named among eight winning ideas selected to progress to the next stage of the competition, which is seeking to solve one of the biggest challenges in decarbonising mining operations: the electrification of haul trucks.

Within this context, BluVeinXL, the company’s new product line, will be capable of dynamically feeding power to heavy-duty mining fleets with up to 250-t payloads.

The technology leverages much of what was developed for BluVein1: a patented slotted (electric) rail system using an enclosed electrified e-rail system mounted above or beside the mining vehicle together with the BluVein hammer that connects the electric vehicle to the rail. This system provides power for driving the vehicle, typically a mine truck, and charging the truck’s batteries while the truck is hauling load up the ramp and out of an underground mine.

To this point, funding support for the BluVein1 project – being developed for vehicles up to 60-t payload and powered by Rethink Mining (Powered by CMIC) – is being provided by Vale, Glencore, Oz Minerals, Northern Star, South32, BHP, Agnico Eagle, AngloGold Ashanti and Newcrest Mining.

BluVeinXL, meanwhile, has seen the company engage with more than 10 “global mining company leaders” in progressing to a pilot demonstration of the technology. While the company plans to announce the names of these supporting mining companies shortly, it says they all see the need for an industry-standardised, OEM-agnostic, safe dynamic power feed infrastructure to suit mixed OEM open-pit fleets.

The key benefits of the dynamic power feeding solution BluVein is pushing are smaller on-board battery packs, faster vehicle haulage speeds up ramp, grid load balancing and maximum fleet availability.

“Our mining company supporters have provided feedback to us on the benefits they see with BluVeinXL over traditional overhead exposed wire catenary systems offered by other OEMs,” the company said. These are:

  • Near to the ground installation enabled by our patented Ingress Protected safe slotted rail technology;
  • Safer and faster installation;
  • Easy relocation as required to suit open-pit ramp movements over time;
  • Requires no heavy civil foundation requirements;
  • Alleviates the requirements on haul road conditions;
  • Offers purchasing flexibility on electric vehicles through the adoption of an industry-standard dynamic power feed infrastructure; and
  • Safer mine sites with no high voltage exposed overhead wires.

The company concluded: “Together with our mining company supporters, BluVein looks forward to working with all OEMs as we progress towards our planned pilot demonstration at a yet to be announced location.”
