This study addresses the intelligent transformation needs of mine material transportation by proposing an integrated intelligent system incorpora-ting high-precision scene perception technologies.A laser scanning positioning system combined with filtering algorithms achieves dynamic monitoring of raw material pools(error＜5％).A multi-algorithm fusion crane positioning model(positioning accuracy±5 mm)and anti-swing control technology(swing amplitude＜5 °)are developed,supported by 5G-enabled transmission and digital twin models for real-time monitoring.The system integrates UWB positioning(15 cm accuracy),infrared barriers and dynamic digital fencing to establish human-machine collaborative safety mechanisms.Experi-mental results demonstrate 20％improvement in crane operation efficiency,personnel positioning errors＜6 cm,and 35％increase in scheduling re-sponse speed.The research validates the synergistic effectiveness of AI and 5G technologies in complex industrial scenarios,providing a multi-technology integration paradigm for mine intelligence.Future research could integrate edge computing to enhance adaptability in dynamic environment.
