Storyline: China launches world's largest fleet of driverless electric mining trucks [Voice_over] At the Yimin open-pit coal mine in northeastern Inner Mongolia, 100 electric mining trucks are working non-stop. They're smart, self-guided, and part of a bold shift in heavy industry. [Stand_up] Li Shuang, Reporter: "At first glance, it looks like just another busy day at the coal mine…but look again. These trucks have no driver, no steering wheel, not even a cabin. They can swap batteries in under six minutes and haul 90 tons for 60 kilometers on a single, full charge." [Voice_over] Developed by energy giant Huaneng Group, the fleet is powered entirely by clean energy and managed by what the company calls the world’s first fully unmanned smart dispatch system. [Sound_bite] Li Shuxue, Chairman, Huaneng Inner Mongolia Eastern Energy Company: "This fully electric, driverless truck is developed entirely in China. It's the most advanced of its kind—combining charging and battery swapping in a high-tonnage, three-axle design that outperforms many domestic and international models." [Voice_over] Tech giant Huawei provides the technological backbone—developing an end-to-end solution from chip to cloud. Using its advanced 5G-A network, the system links every vehicle to a centralized AI-powered dispatch platform. [Sound_bite] Shao Qi, General manager, Open-pit Mine, Oil, Gas and Mining Business Unit, Huawei: "We've created a full-stack solution—from chip to cloud—using 5G-A and AI-driven scheduling to ensure precise positioning and efficient coordination for every." [Voice_over] To navigate harsh terrain and weak signal zones, Huawei combines real-time kinematic positioning with LiDAR and inertial sensors. The result is centimeter-level accuracy—crucial for aligning trucks with excavators and boosting safety and efficiency. [Sound_bite] Shao Qi, General manager, Open-pit Mine, Oil, Gas and Mining Business Unit, Huawei: "In most of the industry, unmanned trucks operate at 90 to 95 percent of the efficiency of manned operations. At Yimin, we're aiming for 120 percent—exceeding what humans can achieve." [Voice_over] Operating in extreme cold, soft rock, and water-rich soil, the Yimin mine is no easy testing ground. Coordinating 100 trucks in such a setting demands technological sophistication. [Sound_bite] Liu Wenbin, Vehicle control engineer, Xuzhou Construction Machinery Group: "We developed a drive-by-wire chassis and our own control system that integrates braking, propulsion, and autonomy. Tasks are optimized within 10 milliseconds. We also use regenerative braking, which recycles energy and extends range." [Voice_over] This driverless mining is a working example of how clean energy and intelligent systems can transform even the heaviest of industries. [Restrictions : No access Chinese mainland]
