Abstract: Based on the analysis of the development status and application of mine trackless auxiliary transportation equipment during the "11th Five Year Plan" and "12th Five Year Plan", the mine explosion-proof electric vehicles, which can effectively alleviate the "four high and one low" problems and occupational health exposed by the current trackless auxiliary transportation equipment powered by explosion-proof diesel engine, are considered as the development direction of the future mine trackless auxiliary transportation technology and equipment field. At present, China’s mining electric trackless auxiliary transportation equipment is in the stage of transformation from scientific research to industrialization. In the process of industrialization, there are still many key technical problems and challenges. This paper elaborates and analyzes the current mining electric trackless auxiliary transportation equipment from the aspects of equipment application state, standard promulgation, and development prospect of key component such as the explosion-proof drive motor, the drive control system, the explosion-proof power battery and their overall design, and puts forward the construction of mine intelligent interconnected pure electric trackless auxiliary transportation equipment based on mine pure electric vehicle auxiliary transportation system platform, and realizes the intelligent information exchange between mine equipment and people, vehicles and roads. Based on the specific working conditions of coal mine, the independent development of vehicle technology is realized. According to the coal mine safety standards, the control technology of new mine explosion-proof power battery explosion-proof drive motor is researched. Meanwhile, the development trend and direction of key technology of mine hybrid power are also concerned. The analysis shows that with the introduction of various industry standards in coal mines ，the perfection of related laws and regulations and the gradual breakthrough of key technologies of mine electric trackless auxiliary transportation equipment such as explosion-proof vehicle, explosion-proof power drive motor, explosion-proof power battery and its management system, mine-used electric auxiliary trackless transport will be a step-by-step development, and can be able to effectively improve the underground working environment and realize energy conservation and emission reduction, and has a good market prospect in the later stage.
