Clean coal processing is one of the trends in the development of the coal industry.During the coal processing,a large amount of coal gangue is produced.In order to achieve clean coal processing,it is necessary to sort coal gangue underground and backfill it into the goaf.In response to the low efficiency of traditional gangue sorting technology,intelligent coal gangue sorting technology has been adopted.This paper analyzed the significance of underground coal gangue sorting,mainly including reducing gangue pollution,reducing transportation costs,and improving coal sorting efficiency.It explored the key technologies of intelligent underground coal gangue sorting,mainly including coal gangue identification technology and coal gangue separation technology,which can provide certain technical references for underground coal gangue sorting.
