Abstract: 　　In order to give full play to the maximum efficiency of trackless auxiliary transportation and guide the designers and purchasers to select the right type of trackless rubber tyred transportation equipment, this paper, based on AQ1064-2008 "code for safe use of trackless rubber tyred vehicles with explosion-proof diesel engines for coal mines" and 2016 "safety regulations for coal mines", and with reference to the performance parameters of the mainstream trackless rubber tyred transportation equipment in the current market, expounds it from a systematic perspective The parameters of roadway section, roadway surface and ramp conditions, design dimensions of various chambers, ventilation requirements and other relevant parameters involved in trackless auxiliary transportation are provided, which provides a reference for the design of trackless auxiliary transportation and trackless transformation of tunnels and chambers.Finally, based on the actual condition data of a mine, the paper discusses the selection process of trackless rubber tyred vehicle in detail, which provides a theoretical basis for the selection of trackless rubber tyred equipment.
