The underground coal mine transportation system can be divided into the main transportation system and the auxiliary transportation system according to the different transportation objects. This paper expounds the status of the bottom equipment and system intelligent technology of the main and auxiliary transportation systems in the underground coal mine in China. This study also analyzes the problems existing in the intelligent technology of the main and auxiliary transportation systems from the aspect of the top planning,standard system and single machine intelligent technology. The three key technologies of intelligent main transportation system are introduced, including distributed communication control technology of belt conveyor based on full digital FCS(fieldbus control system), enhanced protection technology of belt conveyor based on multi-sensor fusion of machine audio and vision, and coordinate economic operation control technology of coal flow. The two key technologies of intelligent auxiliary transportation system are also introduced, including management and control integration technology of underground coal mine auxiliary transportation based on industrial Internet architecture, vehicle-to-everything and unmanned driving technology in underground coal mine.Combined with the requirements of Coal mine intelligent construction guide(2021 edition) for intelligent main coal flow transportation system and intelligent auxiliary transportation system, this paper expounds the intelligent development trend and goal of main transportation system and auxiliary transportation system of underground coal mine from the short term and medium and long term. At present, the research of the main transportation system of underground coal mine in China should focus on the enhanced protection and detection technology of belt conveyor based on multi-sensor fusion of machine audio and vision, intelligent inspection robot technology,etc. And the research of the auxiliary transportation system should focus on the fine closed-loop control and advanced auxiliary driving technologies.
