Aiming at the problems and challenges faced by the extensible belt conveyor in the design and optimization of key components, fault diagnosis, intelligent operation and maintenance of coal mine underground working faces, we put forward the key technologies of the intelligent non-foundation extensible belt conveyor drived by permanent magnet drum, starting from the key technologies such as efficient disassembly, integrated drive, intelligent control and intelligent monitoring.The key technologies mainly involve four aspects: the efficient dismounting and assembling with no foundation for the extensible belt conveyor; high-power permanent magnet integrated driving drum for mines; intelligent permanent magnet frequency conversion tensioning; intelligent monitoring for coal mine belt conveyor. With the above technologies, the safe, efficient, and intelligent operation of the expandable belt conveyor can be achieved, providing equipment support for the intelligent construction of coal mines.
