Mining is the bedrock of recent Australia, in no small measure because of the gold rushes of the mid-1800s. Within the twenty years on from 1851 – as the worldwide industrial revolution was culminating – Australia’s inhabitants rocketed from 470,000 to greater than 1.7 million, largely the results of migrants in search of to capitalise on the bounty of valuable metals the ‘Fortunate Nation’ was constructed on.
With its inhabitants now a pinch over 26 million, Australia continues to depend on mining, which accounted for 13.6% of gross home product in 2023. The nation’s authorities desires extra, recognising its important function it plans to reinforce its mining science expertise functionality, bolster its workforce and even pivot the mannequin to course of extra domestically.
These ambitions supply an abundance of alternative, because the US Worldwide Commerce Administration (US ITA) highlighted in an early-2024 briefing. The federal government-funded export and inward funding advocate for US companies and markets, a part of the Division of Commerce, stated providing buying and selling potential is the truth that the “excessive value of labour in Australia” means there may be sturdy curiosity in automation expertise. This contains, it went on, driverless automobiles akin to vans and trains, drills and excavation tools.
However Australia just isn’t alone in its want to automate a few of its mining tools. Boasting a projected compound annual progress charge (CAGR) of two%, market evaluation and perception supplier GlobalData says the entire variety of energetic machines is forecast to rise to 176,543 internationally by 2030.
On the finish of 2023, it estimates the entire energetic floor mining tools fleet was 153,277, comprising mining vans, which account for 61%, hydraulic excavators at 11%, dozers 14%, motor graders accounting for 7%, wheel loaders at 5.5% and electrical shovels 1.5%.
In 2023, the energetic mining truck inhabitants, excluding these at mines in care and upkeep, was estimated to be 94,207 and forecast to rise to 108,281 by the tip of 2030, matching the CAGR at 2%.

GlobalData says of all mining vans, the most important shares are at coal mines (51%), adopted by iron ore (14%) and gold (13%), with coal significantly dominant in Asia-Pacific and North America.
It lifts the lid on one other probably fascinating pattern too: by truck payload dimension, 71% are beneath or equal to 100 tonnes (t) and 29% better than 100t, indicating that mining vans with smaller payload capacities and shorter lifespans are extra broadly used than bigger ones.
Australia leads in automation of mining tools
“Out of the entire international fleet, Australia accounts for round 7%,” explains David Kurtz, director of mining and building at GlobalData. This contains “an estimated 5,994 vans, 1,956 dozers, 1,064 excavators, 868 motor graders, 747 wheel-loaders and 47 electrical rope shovels,” he says.
Like different components of the worldwide sector, and as instructed by the US ITA, Australia is trying to modern applied sciences. Kurtz, talking extra broadly, gives some perception on what these improvements may be: “Over the previous 5–10 years, now we have seen rising adoption of recent applied sciences at mine websites with the intention to enhance productiveness, scale back value and enhance security. Amongst the traits are an increase in autonomous tools, which is happening each at main floor and underground mines.”
GlobalData is at the moment monitoring greater than 2,000 autonomous or autonomous-ready haul vans at floor mines – greater than a four-fold improve since 2020.
The figures assist that view. Kurtz says the expectation is there are greater than 1,000 tele-remote management and autonomous underground mining vans and loaders, haulers and dumpers (LHDs) in operation. GlobalData says it’s at the moment monitoring greater than 2,000 autonomous or autonomous-ready haul vans at floor mines – greater than a four-fold improve since 2020.
One such web site is Western Australia’s South Flank iron ore mine, owned by BHP, which final yr introduced it had accomplished its autonomous haulage transition, coinciding with its fifth autonomous working zone (AOZ) going reside on the US$3.6 (A$5.42bn) mine.
BHP stated a collaboration with Komatsu had seen it convert 41 930E haul vans and round 185 items of ancillary mining tools together with dozers, excavators, front-end loaders, water vans and different web site automobiles, that means its major haul fleet was in a position to function safely across the web site’s 5 AOZs. The 290t haul vans, automated with Komatsu’s FrontRunner AHS, have Schlam Hercules our bodies and 6 Liebherr 600t R 9600 shovels.
The programme to transition to autonomous haulage was launched at first of 2022, with that April marking the beginning of the conversion. Simply over a yr later and the undertaking was full; different capabilities and networks on the mine had been upgraded and tailored to work with an autonomous fleet and all workers had been retrained or upskilled. BHP says the formidable undertaking was accomplished forward of time and beneath funds.
GlobalData’s market evaluation exhibits BHP has the most important variety of operational autonomous automobiles globally to November 2023, with 368. Likewise, Australia’s mining sector led the world in autonomous automobiles, boasting 882. A ways behind was China with 326, Canada with 250 and Chile with a fleet of 132.
Electrification of mining vans
Whereas autonomy is a key driver of market progress, so too is electrification and battery operation. Printed on the finish of 2023, GlobalData’s International Floor Mining Tools: Populations & Forecasts to 2030 report revealed this was an more and more common space. As of November, GlobalData was monitoring 230 trolley help and 101 battery electrical vans working at floor mines globally.
Zambia, Namibia and Panama had been main the best way in trolley help vans, whereas China was by far the largest investor in battery-powered vans, with 68 identified to be operational. The Chinese language mining sector was additionally main the best way on small-scale battery-powered vans, one thing the report says is burgeoning.
Nonetheless, the focus will maybe shift from China slightly as, says the report, large-capacity, battery-powered floor electrical truck prototypes are being examined in Australia and South Africa.
With the rising urge for food for extra sustainable fleets and an rising focus of the sector to chop emissions, it appears extra is to return. “The usage of electrical and battery-electric tools is rising, being pushed partly by the necessity to scale back scope 1 emissions at mine websites, but additionally supporting diminished upkeep and different operational prices,” says Kurtz.
“Whereas many miners are wanting on the subsequent decade for extra complete adoption of electrical automobiles,” Kurtz provides, “there was widespread trialling and a few preliminary adoption of electrical and battery-electric tools, significantly underground.”
GlobalData has recognized greater than 400 trolley-assist and battery-powered floor vans in operation, in addition to over 330 electrical vans and or LHDs working underground. This will likely simply be the beginning, with BHP, Rio Tinto, Newmont, Teck and Freeport-McMoRan amongst these hoping to develop the subsequent technology of zero-emission vans although collaborations with Caterpillar (CAT).
Working with CAT, in 2021, Rio embarked a undertaking to deploy what each stated can be the world’s first fleet of CAT 793 zero-emissions autonomous haul vans. It stated that its then beneath growth $2.6bn Gudai-Darri iron ore mine in Western Australia would obtain the fleet of 35. The mine, located within the Pilbara area roughly 35km north-west of Rio’s Yandicoogina web site, had already been chosen for totally autonomous CAT 789D water vans, which Rio hoped would assist additional improve productiveness.
Market shift anticipated by 2030
It appears there’s a main shift coming to mining, specifically the fleets it operates and the abilities wanted to take action. Miner and OEM collaborations are serving to to facilitate that, leading to equipment that isn’t solely more and more sustainable however now extra customised than ever earlier than.
Of the projected 176,543 energetic international mining machines by the tip of the last decade, GlobalData says vans will make up the lion’s share. It believes the most well-liked payloads will probably be 50–99 tonnes (36%); 35% will probably be beneath that, after which quite a few dozers accounting for 14% and hydraulic excavators and shovels at 11%. The necessity for vans will proceed, however proper now it’s the innovation they carry that catches the headlines.
GlobalData estimates that electric-powered LHDs will rise from simply 1% in 2023 to virtually 9% by 2030.
“In addition to the present depend of two,095 autonomous haul vans in operation, plans revealed by miners present a minimum of one other 300 to be added by 2026,” Kurtz reveals. “The place electrical automobiles are involved, a gradual improve is anticipated over the rest of the last decade as extra current mines trial battery-electric machines and a small variety of new mines start operations with important numbers of battery-electric machines from the outset.”
Right here is the eye-catcher: as a proportion of the entire fleet, GlobalData estimates that electric-powered LHDs will rise from simply 1% in 2023 to virtually 9% by 2030, earlier than a quicker acceleration within the subsequent decade. It appears the vitality transition that mining is important to facilitating has certainly reached one of many oldest industries itself – clearly the ‘Fortunate Nation’ will take a number one function.
