Abstract: Electrification, intelligence and network connection will be the three major technological changes in the future of trackless transportation in coal mines. It is the general trend to use information, communication and control technology to closely combine vehicles, road conditions, personnel and materials and finally realize intelligent interconnection. In order to solve the outstanding problems of high security risks, serious pollution and low resource utilization rate in the current trackless auxiliary transportation industry of coal mine, and improve the transportation efficiency and intelligence degree of coal mine, a comprehensive system of intelligent interconnection and new energy trackless auxiliary transportation for mining is put forward. In view of the proposed intelligent interconnection comprehensive system, the present technical situation at home and abroad and relevant national industrial policies are first described, and the future supply and demand relationship of the global coal market, the market scale of the trackless auxiliary transport vehicles and the economic benefits brought by the trackless auxiliary vehicles with green environmental protection as the main element are analyzed. New architecture based on new energy vehicle structures, intelligent systems, the more dominant in aspects such as power supply, digital signal acquisition, avoiding the problem such as car fuel modulus conversion, and at the same time with the new energy vehicles as the carrier through the 5G communication platform, with a highly integrated intelligent scheduling, management system as the foundation, steadily improve the overall level of coal mine auxiliary transportation system in our country, Improve the current situation of low level of information, intelligence and automation, greatly enhance the modern management level of coal mining enterprises. Then, under the premise of ensuring the safety of coal mine, five key technologies are extracted for the purpose of improving production efficiency to achieve the system, aiming at improving the intelligent perception ability of coal mine vehicles and finally realizing unmanned driving. Finally, it reveals the problems that the system faces due to the complex underground environment and technical bottlenecks, and looks into the future prospects of the trackless assisted transportation system, and finally forms the integrated solution of intelligent trackless assisted transportation control in coal mine and applies it in typical coal mines.
