Autonomous Mining Trucks Achieve Precision Passing on 12-Meter Narrow Roads

In a limestone mine in Tongchuan, Shaanxi Province, unmanned mining dump trucks operated by China Railway 19th Bureau Group are achieving precise vehicle passing and automatic loading on 12-meter narrow roads, all without human intervention. This smart mining transport system represents the culmination of years of dedicated work by technical lead Si Xiangsheng, who has been deeply involved in mine intelligence for years.

World Model Technology Breakthrough

The 12-meter narrow road is universally recognized as an extreme operating scenario in the industry. Old mines cannot designate exclusive autonomous driving zones, which has long been a pain point restricting industry intelligence upgrades. Si Xiangsheng innovatively introduced world model technology, building virtual simulation scenarios that precisely match real mining areas, conducting unlimited simulations to optimize truck trajectories. The system achieved centimeter-level trajectory tracking, with testing efficiency improved by 30%.

Relying on full-stack perception-decision-control technology, the system overcame harsh environment operational challenges. In heavy fog, it can accurately reconstruct three-dimensional scenes. At night, the 90-ton mining truck achieves warehouse docking with errors controlled within 10 centimeters. In mixed autonomous and human-driven vehicle mode, mining transport efficiency experiences zero loss.

International Recognition

In 2024, Si Xiangsheng led his team to break through 7 core technology barriers and secured 23 patents. In 2025, his intelligent connected unmanned mining truck technology debuted at the Geneva International Exhibition of Inventions, winning both the Special Grand Award and the Invention Gold Award, demonstrating the strength of Chinese intelligent manufacturing.

His team has participated in compiling China's first blue book on unmanned driving in mining areas. Standing on the international stage, Si Xiangsheng expressed confidence that China's mining intelligence technology has joined the ranks of the world's most advanced.

Talent Development

While deepening technology development, Si Xiangsheng has dedicated himself to cultivating talent. He formed a technical assault team that solved 32 on-site technical challenges, established a technical night school, trained 56 professional technical backbones, and created a local technical team capable of self-iteration. From iron mines in Shanxi to copper mines at 5,000 meters altitude in Tibet, he has worked through extreme conditions to solve vehicle deviation problems and develop laser radar local positioning systems for 100-ton mining trucks.
