Development status and key technology of mine electric driving trackless transportation vehicles

According to a late domestic industrial study on the mine electric driving trackless transportation vehicle and the study orientation mainly on a mine explosio n proof lithium battery personnel transportation vehicle,the paper introduced a development status of the mine electric driving trackless transportation vehicles at home and abroad,summarized two development orientations of the lightweight vehicle and heavy duty vehicle and analyzed the features and key technology research orientation of th e lightweight battery technology,lightweight structure technology and explosion proof permanent magnet motor related to the lightweight vehicle as well as the complete ve hicle technology and frequency control technology related to the heavy duty vehicle. Finally,a forecast was provided on the development and technology breakthrough orien tation of the explosion proof battery technology,lightweight technology,energy saving technology and other aspects related to the mine electric driving trackless transportati on vehicle.
