Research on auxiliary transportation system of double-electric trolley in mine
LIU Yu-rong
Abstract：In order to find an effective solution for vehicle pollution and long distance and large slope transportation in underground coal mine, a new type of mine double-electric trolley auxiliary transportation system is put forward. The system is composed of power supply system, overhead line system, charging station, collector and double electric trolley. It has three operation modes: quick charging, stringing and mixing. In this paper, the key technical indexes of each subsystem are put forward, and three operation modes are expounded in detail. Finally, three key technologies of the auxiliary transportation system are proposed, including traction substation capacity and power supply arm matching technology, overhead line change line technology, power battery selection and matching technology, the corresponding solutions, to provide technical support for the future realization of trolley auxiliary transportation system.
