Abstract: The problems and challenges faced by the expandable belt conveyor in the design optimization, fault diagnosis, intelligent operation and maintenance of key components for the underground working face of coal mines. Starting from the key technologies such as efficient disassembly, integrated drive, intelligent control and intelligent monitoring, this paper puts forward the key technologies of the intelligent permanent magnet integrated driving pulley non-foundation telescopic belt conveyor. It mainly involves four aspects: there is no foundation for the telescopic belt conveyor and the highly efficient dismounting technology; Mining high-power permanent magnet integrated driving pulley technology; Intelligent permanent magnet frequency conversion tensioning technology; Intelligent monitoring technology for coal mine belt conveyor. Through the above technologies, the safe, efficient, and intelligent operation of the expandable belt conveyor can be ultimately achieved, providing equipment support for the intelligent construction of coal mines in the coal industry.
