Technical analysis of safety performance for mining flame-proof trackless vehicles powered by lithium battery

According to the present situations of temporary non related national and industrial standards and non equipment design, test and certification basis for t he present mine flame-proof trackless rubber tyre vehicle powered with a lithium battery, in a full consideration of the available related standards and regulations as wel . I as the severe operation environment and the complicated performances of the vehicle in an underground coal mine, with the lithium battery, chassis, vehicle body and the key structure and components of the mine flame-proof trackless rubber tyre vehicle powered with lithium battery as the main object, the study provided the optimize d selection and safety application of the lithium battery, the rational design of the chassis and vehicle body structure, the optimal allocation of the automatic protection a nd monitoring system and other aspect safety requirements. The requirements would have the application certification on the design and test of over 20 set trackless ru bber tyre vehicles powered with the lithium battery from 6 enterprises. The results showed that in comparison with the flame proof diesel engine trackless rubber tyre ve hicle, the operation cost of the flame-proof lithium battery trackless rubber tyre vehicle could be reduced over 3/4 and the attendance rate of the flame-proof lithium batt ery trackless rubber tyre vehicle could be improved by near 30%.
