Abstract: In the process of ore mining,the operation efficiency and safety of blasting process have an important impact on the construction of intelligent mine. In order to improve the automation and mechanization level of industrial explosive field mixing technology,an intelligent field mixing emulsion explosive vehicle ( referred to as intelligent mixing vehicle) was designed. The structure,process principle,key technology and field use flow of intelligent mixing vehicle were introduced in detail,and the engineering application was carried out. The study results show that:① The intelligent mixed loading vehicle realizes the functions of automatic hole finding,remote control of holes,intelligent charge,intelligent fault investigation,remote data management,etc. ,which improves the automation and intelligent level of explosive field mixed loading technology;② Realize real-time extraction of charge parameters,intelligent adjustment of charge density,ensure accurate matching of explosive density and rock crushing energy, and significantly improve the utilization rate of explosive energy; ③ The total charge efficiency (charge per person per minute) is 2 times that of ordinary mixed vehicles,4. 7 to 7. 0 times that of human tooling,which improves work efficiency and reduces labor costs,and only 1 person is needed for charging personnel in the entire blasting area, reducing the possibility of exposing personnel to dangerous environments and achieving intrinsic safety. The study results have successfully realized the safe and efficient charging of long-distance,multi-directional and multi-scene open-air blasting,which is helpful to improve the technical level of intelligent charging in China.
