Abstract: Based on the analysis of the main factors affecting the selection of mine auxiliary transportation modes, the paper puts forward the applicable conditions of various kinds of auxiliary transportation modes. The existing trackless transportation system and the track transportation system are divided and compared in detail, this paper expounds the advantages of the trackless transportation system from several aspects such as transportation capacity, transportation speed, number of auxiliary transportation personnel, transfer links, occupying equipment, auxiliary work, etc. , the characteristics of less reloading links, fast running speed, large carrying capacity, fast running speed, less assistant personnel and low transportation cost are presented. Finally, it is put forward that popularizing trackless transportation system in newly-built mines and technical transformation mines can realize the reduction of personnel and increase efficiency, the construction of high-yield and high-efficiency mine is of great significance.
