The system adopts long-range 4D millimeter-wave radar and UWB high-precision positioning integration technology to achieve centimeter-level positioning in a GPS-free environment. Combined with the V2X vehicle-road coordination system, it enables automatic obstacle avoidance, intelligent meeting and passing, and precise parking. By 2026, the system had expanded to 7 coal mines, with cumulative transported material exceeding 1.2 million tons, dispatch efficiency increased by 40%, and manual intervention frequency reduced by 90%. Its success marks that mining transport robots have moved from the "pilot demonstration" stage to a new stage of "large-scale replication".
