Automation and digitalisation have been scorching subjects within the mining business for a while, with totally different firms additional alongside of their digitalisation journey than others. It’s properly understood that deploying machines underground to work 24-7 can create operational efficiencies and enhance security – however there’s one other vital profit to be gained from underground automation: reducing challenge GHG emissions.
In EY’s 2024 annual survey of mining executives, environmental, social and governance (ESG), capital, licence to function and local weather change stuffed the highest spots. When requested what ESG elements are dealing with probably the most scrutiny from traders in 2024, 46% stated attaining net-zero emissions.
It’s clear that decreasing operational emissions is changing into a significant focus for miners. As outlined in an OECD report, Mining and Inexperienced Progress within the EECCA Area, underground autonomous mining tools has a key function to play in enhancing the sustainability of mines. For instance, it highlights that automated air flow methods at underground mining websites can save as much as 40% of vitality prices, in flip reducing operational emissions.
One other report, produced by lecturers in Canada and looking out particularly at underground copper mining, is equally constructive. Its mine life cycle evaluation finds that the reductions in CO₂ emissions from utilizing automated tools, and growing effectivity and displacing diesel vans, may lower international warming potential by 17.9kg of CO₂ equal per tonne of ore.
That is vital on condition that international copper demand, pushed by AI and the vitality transition, is predicted to extend by 29% by 2030, in accordance with GlobalData.

Nevertheless, funding in automation for underground mining is growing and appears set to select up tempo, says Ben Moens, managing director at ENGIE Influence, a consultancy that works with firms to satisfy their sustainability objectives.
“Underground mining is changing into more difficult as time goes on as a result of a lot of the low-hanging fruit has largely been carried out, so mines are getting deeper or extra distant,” he says. “This can put better emphasis on the automation of underground mining to make sure that mining will be carried out in an environment friendly, secure and sustainable approach.”
Latest investments in an autonomous haulage system by Canadian gold producer Alamos Gold at its Younger-Davidson mine in northern Ontario are illustrative of this development.
As a part of a decrease mine enlargement in 2020, the corporate put in a 600m electrical conveyance and hoisting system to move ore out of the mine. The system, which is digitally managed by a single hoist operator above floor, changed six diesel haul vans, decreasing the mine’s general fossil gas necessities. It’s also powered by the Ontario grid, which is majority equipped with low-carbon energy.

As such, the system has halved the mine website’s GHG emissions depth in contrast with 2020 (earlier than the enlargement), says Luc Guimond, chief working officer at Alamos Gold. The conveyance system, in contrast with the diesel vans, requires much less upkeep, personnel and air flow.
“The motivation for switching from diesel haul vans to an electrical conveyance system was to decrease the mine’s general value profile and to realize increased throughputs with the enlargement but additionally cut back GHG emissions. They’re actually all intertwined,” he says. “We at the moment are properly arrange for the long-term profit, each from a price perspective in addition to a GHG emission depth discount perspective.”
The location can be transitioning to electrical personnel carriers (it has three, with two extra on order) and hybrid underground scoop trams.
An analogous enlargement can be underneath approach at its Island Gold operations, additionally in Ontario. The present ramp system shall be changed with an electric-powered mine shaft, which is able to allow the mine to double manufacturing to 2,400 tonnes per day and displace round 12 diesel vans.
Mine haul fleet electrification is without doubt one of the best and real looking methods to scale back CO₂ emissions in mining and assist the business attain its sustainability targets, says Jan Nyqvist, product supervisor for automation – underground mining at know-how supplier ABB Course of Industries.
Nyqvist factors to one of many world’s largest items of mining business infrastructure, the 13km Takraf belt conveyor system put in at Codelco’s Chuquicamata underground mine challenge in northern Chile. The belt removes the equal of 120 giant haul vans for the transportation of copper ore, decreasing CO₂ emissions by 70%, in accordance with the mining operator. ABB employs 11 x 5MW gearless conveyor drives to maneuver the belt, overcoming an altitude of 1.2km.

“Automation is a key contributor to decreasing emissions,” says Nyqvist. “That is demonstrated by the automated, demand-based air flow system we put in at Boliden’s mines in Sweden that returns annual vitality financial savings of greater than 50% in comparison with different methods – ventilating a whole mine can usually value half of the working expenditure annually.”
As well as, working with Boliden and mining machine tools supplier Epiroc, with funding from Swedish innovation company Vinnova, the three firms have developed, examined and demonstrated the world’s first absolutely battery-electric trolley truck system for underground mining. This has enabled the ABB Capacity eMine trolley system to work underground after profitable deployment in open-pit mines.
Integration challenges and new alternatives for interoperability
Integrating autonomous know-how right into a mine website will be difficult, nonetheless. Frequent points embody a lack of knowledge inside the firm, the upfront capital value and prioritising the funding and belief within the know-how readiness.
“Adapting new automation know-how requires personnel who’re prepared to alter the way in which they’re working, with established mining nations and people with excessive labour prices adapting faster to automation,” explains Nyqvist.
Sooner or later, new alternatives from digitalisation and automation will come from interoperability and the sharing of knowledge throughout totally different autonomous tools and between mines, says Moens.
“This could additional drive efficiencies and carbon financial savings; with this information, and the leveraging of developments in industrial computing in addition to the usage of algorithms, firms may have entry to automated identification and corrective motion to resolve a spread of issues – from manufacturing and upkeep to security,” he added.
Sustainability drivers to undertake this know-how will definitely turn into extra acute. Many miners have already got net-zero ambitions and face necessary emissions reporting. If they’re to ship the insatiable demand for brand new vitality metals and minerals – between 2017 and 2022, demand for lithium tripled, demand for nickel rose by 40% and cobalt 70% – they might want to embrace the know-how.
Nevertheless, it’s essential for firms to not weigh up decarbonisation efforts in opposition to different initiatives – they should be considered a enterprise crucial, alongside issues like reducing prices or driving income, says Moens.
“Within the mining business, to make sure that firms keep aggressive in a quickly evolving market, in addition to retaining the belief of stakeholders and prospects, working each effectively and sustainably should be thought of of utmost significance,” he concludes.
