Mining Trucks With No Driver's Seat at All
A fleet of 100 autonomous electric mining trucks now operates at a Chinese coal mine, running driverless in temperatures as low as -40°C with no cabin for a human at all.

Half of a Mine's Accidents Traced to One Cause
At the Yimin open-pit coal mine in Inner
Mongolia, one number stood out above every other safety statistic:
transportation accounted for half of all incidents at the site. Four rotating
teams of drivers worked around the clock to keep trucks moving, in temperatures
that plunge to -48.5°C, through dust storms, fog, and the kind of terrain that
turns a routine haul into a hazard. The mine needed a fundamentally different
approach to moving earth and coal, not a safer version of the same system.
Huaneng Inner Mongolia Eastern Energy Co.,
Ltd., which operates the mine as part of the state-backed China Huaneng Group,
found that approach by removing the driver entirely. In partnership with heavy
equipment maker XCMG and technology provider Huawei, the company deployed a
fleet of 100 Huaneng Ruichi autonomous electric mining trucks, officially
entering operation on May 15, 2025. It stands as the world's first fleet of its
size and kind: fully driverless, all-electric, and built without a cabin for a
human operator at all.
A Truck With No Seat for a Person
The most immediate fact about the Huaneng
Ruichi truck is what it lacks. Unlike autonomous vehicles that keep a driver's
seat as a backup, these trucks were built with no cabin at all, a design
decision that reflects the company's priority above all else: keeping people
away from dangerous equipment and extreme conditions entirely rather than
simply automating the wheel. Each truck carries a payload of 90 metric tons,
the largest capacity recorded for autonomous electric mining trucks, and
reaches a top speed of 50 km/h while continuing to operate in temperatures as
low as -40°C, another record for the category.
Removing the driver does not mean removing
awareness. Each truck carries a perception system built from multiple LiDAR
units, millimeter-wave radar, and cameras, delivering 360-degree,
all-directional coverage with no blind spots. In practice, the trucks maintain
stable object detection at distances up to 40 meters even in heavy snow,
sandstorms, or complete darkness, conditions that would sharply limit a human
driver's visibility. The system automatically identifies walls, boundaries, and
elevation changes, executes decimeter-level automatic parking, and adjusts
driving behavior for steep descents and rough terrain, including balanced
rolling to keep the truck stable.

Zero Diesel, Six-Minute Battery Swaps
The trucks run entirely on electricity charged
from solar power, and depleted batteries are swapped automatically in under six
minutes, keeping the fleet in near-continuous operation without long charging
pauses. The environmental accounting is direct: completing the annual workload
of these 100 trucks with conventional diesel vehicles would require more than
15,000 metric tons of diesel fuel, generating roughly 48,000 metric tons of
carbon dioxide emissions. Solar-powered electric operation eliminates that
output entirely.
The safety impact runs alongside the
environmental one. With no driver's cabin and no human exposure to the mine's
harshest conditions, an entire category of workplace risk- equipment hazards,
extreme cold, poor visibility- simply no longer applies to the people who once
filled that role. Mining remains dangerous work in many respects, but the
specific danger of driving a loaded truck through a blizzard has been removed
from human hands altogether.
Building Toward a Fully Automated Mine
The Yimin deployment is explicitly a first
phase rather than an endpoint. China Huaneng has stated plans to expand the
autonomous fleet at Yimin to between 300 and 500 units, and to replicate the
model at other mining sites, including operations in China's Xinjiang region.
As of recent reporting, the fleet has already logged thousands of operating
hours and moved millions of tons of material since launch, giving the project a
track record beyond its opening ceremony.
The broader significance reaches past any
single mine. China's coal industry remains central to the country's energy
strategy, and the sector overall expects the number of autonomous mining trucks
nationwide to exceed 10,000 by 2026. What the Yimin project demonstrates is not
just that autonomous trucks can work, but that an entire mine's transportation
system- vehicles, network, cloud coordination, and power source- can be
redesigned together as one system rather than automated piece by piece. For an
industry historically defined by danger and heavy emissions, that combination
points toward a genuinely different operating model.
