Three years after the launch of ABB’s eMine™ ecosystem, the results speak for themselves: six operational trolley systems, a proven fast charging system and numerous project leads in the offing.
Speaking to Ratna Kanth Dittakavi, Global eMine Sales Manager, it is clear the best is still yet to come from the ABB business line.
In the lead-up to a showcase of the company’s underground trolley capabilities at Boliden’s Rävliden mine in northern Sweden this week, Dittakavi was effusive about the company’s prospects – both with OEMs and mining companies.
He was able to share such foresight with numerous eMine consultative studies ongoing.
“We have about a dozen of these studies going on at the moment,” he told IM. “These are all in various stages of development – from prefeasibility study and feasibility, through to engineering.”
Such studies underpin the company’s eMine execution strategy, considering all electrification options for clients and coming up with a tailored, technology-agnostic plan for the company.
ABB’s close ties with a growing number of OEMs and suppliers – it recently signed a collaborative agreement with Komatsu, for example – plus its ability to carry out the majority of electrification, automation and digital work on its own, differentiates this offering from the standard engineering or consulting services available to mining companies or contractors.
“When we come up with an electrification plan for a client, say, 3-5 years ahead of production with 10-15% contingencies, we have to execute it for them,” Dittakavi says. “We don’t devise these studies for someone else to enact them. It goes beyond project execution too, as we’re often supporting the electrical infrastructure on site throughout the life of the mine.”
Early engagement is the key to being able to devise these strategies with clients, according to Dittakavi, however when looking at the six trolley projects the company is currently able to talk about – Aitik, Aitik Extension, the second trolley line at Kevitsa, Copper Mountain, Los Pelambres and Rävliden – he admits that the engagement timeframe hasn’t always been consistent.
“Just as we look to come up with a tailored solution for the client depending on their green energy inputs, site-wide infrastructure and load and haul fleet, for example, we also have to work within the constraints of the project timelines we are given,” he says.
Outside of the existing trolley projects the company is working on – including the 800-m test track at Rävliden – ABB is also working on a Robot Automated Connection Device (ACD) to charge future battery-electric trucks. This is planned to be a fully automated interoperable connection device working in tandem with the ABB eMine Fast Charge solution.
The ACD is set to be showcased in some form at next month’s MINExpo INTERNATIONAL 2024 event in Las Vegas IM understands, with a prototype also set to arrive at Boliden’s Aitik mine shortly for testing with a “dummy plug” connection, Jonas Ranggård, Program Manager at Boliden Mines, confirmed this week.
