Perched 5,600 metres above sea level in the Kunlun mountains of northwest China, the Huoshaoyun lead-zinc deposit has begun round-the-clock production powered not by miners but by fleets of autonomous haul trucks. Chinese engineers began large-scale testing of the vehicles in late 2025 and, by January 2026, officials said the €45 billion project was ready for continuous, human-free operation, transforming one of the world’s highest and harshest mines into a proving ground for next-generation automation.
Built on a contested plateau in Aksai Chin, the operation is run by Guanghui Energy and coordinated from a control centre hundreds of kilometres away. The company says the move to unmanned trucks—guided by radar, lidar, high-resolution cameras and a private 5G network—will curb accidents, cut labour costs and keep metal flowing even when blizzards, sub-zero temperatures or thin air would force human crews to halt.
The transformation addresses a single question confronting modern resource projects: how do you safely and profitably tap remote, high-value deposits that push human endurance to its limits? China’s answer, showcased at Huoshaoyun, is to replace much of the on-site workforce with an integrated system of sensors and self-driving machinery that can run 24 hours a day, seven days a week.
China’s highest proving ground
Engineering teams began live trials of domestically built autonomous trucks at the site in December 2025. During those tests, the vehicles “successfully completed ore transport at 5,600 metres with 5G-enabled intelligent operation,” Highways Today reported. Less than a month later, environmental commissioning wrapped up and management declared the mine ready for full-time autonomous haulage, according to an article published 9 January 2026 by Ecoportal.
The South China Morning Post confirmed that the fleet comprises “domestically developed unmanned mining trucks” that can navigate steep, icy switchbacks without a driver in the cab, reducing exposure to frostbite, altitude sickness and avalanches. In initial production runs the trucks “successfully completed ore transport, contributing to safety in extreme conditions,” the newspaper said in its science section coverage of the trial phase.

How the system works
From a bank of panoramic screens in the remote operations centre, technicians track dozens of vehicles in real time. Each truck carries a suite of sensors: millimetre-wave radar for obstacle detection, lidar for 3-D mapping, and optical cameras for lane keeping and object classification. High-performance onboard computers fuse these data streams and feed instructions to the drive-by-wire system, steering the 90-tonne units along pre-mapped corridors between the pit and the crusher.
A dedicated 5G network blankets the plateau, providing millisecond-level latency so operators can intervene if the software flags an anomaly. Under normal conditions, however, the vehicles make their own decisions about speed, following distance and emergency braking. They also communicate vehicle-to-vehicle to avoid convoys piling up on narrow alpine roads.
Site managers say the core advantage lies in what the trucks do not need: oxygen tanks, rest breaks or heated cabs for human comfort. Engines idle only for scheduled maintenance and refuelling, and dispatch algorithms can reshuffle routes instantly when rockfalls or white-outs close a ramp.
Why Huoshaoyun matters
Huoshaoyun’s ore body contains some of Asia’s richest concentrations of lead and zinc—metals essential for battery anodes, galvanised steel and specialised alloys. With global zinc hovering near €2,500 a tonne and lead around €1,970 in late 2025, even marginal improvements in extraction efficiency could translate into hundreds of millions of euros in annual revenue.
Yet the same plateau that hosts these metals is notorious for its dangers. Temperatures can plummet to –20°C; oxygen levels are 40 per cent below those at sea level; and the permafrost undermines conventional roadbeds. Before automation, mines at similar altitudes reported productivity losses of up to 50 per cent as workers acclimatised and equipment battled ice-clogged filters. By moving the labour component off-site, Guanghui Energy expects to reclaim many of those lost hours and stabilise output.
Safety officials also point to the reduced risk of catastrophic incidents. In the thin air, even minor slips or equipment fires can be fatal because rescue teams require extra time to reach the site and victims may succumb to hypoxia en route. Removing drivers from haul trucks—the most frequent source of heavy-equipment accidents—eliminates one of the mine’s largest exposure zones.
Inside the control room
Operators seated in an urban command centre receive a constant stream of high-definition video and lidar point clouds. When software detects a boulder obstructing a haul road, it automatically slows the approaching truck and transmits an alert. An engineer can then assume remote control, steering the vehicle around the obstacle or ordering an autonomous bulldozer to clear the path. If the 5G link drops, the truck’s fallback algorithms instruct it to stop in a safe zone and wait for reconnection, reducing the danger of runaways on steep grades.
Machine learning models continually analyse vibration data from wheel hubs and suspension arms to predict mechanical failure before it happens. Maintenance crews schedule interventions during weather windows, swapping out parts in heated sheds to keep the fleet above 90 per cent availability—an uptime figure difficult to match with human drivers at such altitudes.
Economic calculus
The mine’s development cost is estimated at €45 billion, a price tag that includes the underground workings, ore-processing plant and the communications backbone that makes autonomy possible. Even modest improvements in throughput can speed payback; a single additional tonne of concentrate hauled each minute translates into roughly 500,000 tonnes over a typical year. Running 24 hours a day means the trucks could add three extra “shifts” of capacity compared with human-crewed operations, while energy consumption per tonne drops as idling and stop-start cycles decrease.
Regulatory and geopolitical backdrop
Huoshaoyun sits in Aksai Chin, a region administered by China but claimed by India. While Beijing says the project is well within its territory, New Delhi has previously objected to large-scale infrastructure in the area. Thus far, neither side has publicly protested the move to automation, perhaps because unmanned trucks do not involve relocating a large workforce or building new road links across contested passes.
Domestic autonomy, global showcase
Chinese engineers emphasise that both the haul trucks and the control software are built in-house. That matters because multinational mining giants—particularly in Australia’s Pilbara and Canada’s oil sands—have long touted autonomy as their competitive edge. By demonstrating similar or better performance at 5,600 metres, China positions itself not only as a minerals supplier but as a potential exporter of high-altitude mining technology.
Industry analysts note that Rio Tinto and BHP run some 600 driverless trucks in the Pilbara, yet none operate above 1,100 metres. If Huoshaoyun’s system proves reliable, it could open new frontiers in Tibet, the Andes or even sub-Arctic zones where conventional crews cannot work year-round.
Innovation hurdles ahead
Despite early successes, challenges remain. The mine’s 5G network, while fast, is vulnerable to icing on antenna masts and solar-powered relays. Engineers are experimenting with redundant microwave links and hardened fibre to guarantee uptime during winter storms. Cybersecurity is another concern; a breach that seizes control of autonomous trucks could endanger lives and halt production. The company says it has air-gapped critical control loops and installed real-time intrusion detection, but independent audits have not been published.
Long-term, the biggest unknown may be regulatory. International guidelines for autonomous vehicles on public roads are still evolving, and mining legislation in many countries assumes a human is on board mobile equipment. Should China choose to export its high-altitude system, it will need to align with disparate legal frameworks and safety standards.
Broader implications
Autonomous haulage at Huoshaoyun signals a shift in how resource companies balance capital and labour. Instead of investing in oxygen tents, medical clinics and rotating crews, operators can pour funds into sensors, code and communications. Human expertise moves to the back office, analysing data and managing exceptions rather than sweating in the pit. If replicated at scale, the model could reshape employment patterns in remote regions, with fewer on-site jobs but potentially more high-skilled positions in urban control centres.
Critics caution that technology cannot eliminate all risk. Avalanche mitigation, tailings management and environmental stewardship still rely on human judgement. And while driverless trucks reduce exposure for one group of workers, they introduce new dependencies on software integrity and network resilience.
Even so, the Kunlun experiment provides a glimpse of mining’s likely trajectory: smart machines tackling the dirtiest, most dangerous tasks while humans orchestrate from afar. Whether the concept flourishes will depend on economics, regulatory buy-in and the ability to secure complex systems against both nature and cyber threats. For now, Huoshaoyun stands as a real-world laboratory five vertical kilometres above sea level—one where the future of heavy industry is already grinding uphill, unaccompanied.
