Abstract：In recent years,emerging enterprises and technology have developed rapidly,and unmanned driving technology is widely used in various open-pit coal mining fields.Open-pit mining is a large-scale production enterprise with stripping as the core and transportation as the link.The utilization rate of equipment and the level of production organization to a certain extent determine the efficiency of the enterprise.The new generation of unmanned driving technology includes wireless communication technology,high-precision positioning technology,intelligent vehicle terminal equipment,and linear programming theory.Intelligent mine unmanned driving technology is nec-essary to further improve the development trend of precise positioning technology,material hazard perception technology,multi-party wireless communication technology,and collaborative operation technology.The current status of unmanned driving technology in open-pit mines at home and abroad was analyzed,a detailed introduction to the key technologies of unmanned mining vehicles in open-pit mines was provided,including the advantages and disadvantages of millimeter wave and LiDAR,infrared ultrasonic technology,visual perception,4D optical scene perception analysis,and other technologies.The development direction was to highly integrate multiple sen-sors into vehicle all-weather environmental perception.By comparing inertial navigation,GNSS differential perception,vehicle networking positioning,electronic map and visual sensor fusion,and considering the limitations of open-pit mining,an unmanned driving plan for open-pit mining was proposed to be organically combined with the standardized workflow of the mine,ultimately achieving unmanned driving of mining vehicles for transportation in the mining area.At present,research on unmanned driving technology in China mainly fo-cuses on specific control methods such as path tracking,safe passage,and auxiliary decision-making,which are insufficient to support the normalized operation of the entire mining area transportation system.A set of engineering and technical solutions was proposed to ad-dress this issue,including three aspects:cloud control center,edge side,and intelligent terminal.This specifically includes unmanned vehicle driving,cloud control scheduling platform,unmanned transportation simulation,remote emergency takeover system,health man-agement,collaborative operation management,and positioning communication.Unmanned driving trucks in open-pit mines can achieve functions such as obstacle perception,intelligent decision-making,path planning,high-precision positioning,and precise control.
