Abstract: Based on the study of the research status and development direction of unmanned driving technology applied in mine transportation field, the transportation safety risks of open pit mines were analyzed.The unmanned driving technology was divided into wire control technology, environment sensing technology, positioning and navigation technology, path planning technology, and decision control technology according to the specific functions, and the advantages and disadvantages of each key technology implementation method were analyzed. Based on the study above and the analysis on each key technology, it was concluded that multi-technology integration to realize environment sensing, positioning navigation, path planning and decision-making control is the inevitable trend of the development of unmanned driving technology in mines.
