Abstract: In view of the existing problems of low intelligentization level,traffic congestion,low transportation efficiency,high labor costs and manual operational risks,difficulty in dynamic coordination and others in the auxiliary transportation of Jinjitan Coal Mine,based on the theory of "intelligent coordination,precise scheduling,safety and efficient",a set of intelligent unmanned transportation system for mine auxiliary transportation vehicles is designed.The system integrates five modules such as intelligent scheduling management,unmanned driving,V2X vehicle road coordination perception,remote monitoring and emergency takeover,and auxiliary operation.Adopting technologies of multi-sensor fusion,SLAM synchronous positioning and mapping,5G communication,and big data optimization scheduling to solve problems such as dynamic scheduling,precise perception,path planning,multi vehicle coordination control and others of downhole tasks.The application shows that after application,the system reduces the number of working personnel,greatly improves the efficiency of auxiliary transportation,reduces the incidence of auxiliary transportation accidents,economic and safety benefits are significant.The research results provide important technical support for the construction of smart mines and provide practical experiences for the intelligentization transformation of coal industry.
