Abstract: In view of the low degree of automation，low efficiency and poor safety of fully mechanized excavation face in coal mine，a new intelligent excavation control system in coal mine is proposed. The multi-machine cooperative operation control of fully mechanized excavation face is realized by comprehen⁃ sively using remote centralized control technology and human-machine-environment cooperative control technology. The practical application shows that the new intelligent control scheme can improve the efficien⁃ cy of underground roadway fully mechanized excavation by 25.5 %，and reduce the number of fully mecha⁃ nized excavation face workers by 33.3 %. It is of great significance to improve the economy of underground fully mechanized excavation and realize ' unmanned ' fully mechanized excavation.

Key words: intelligent excavation, advanced detection, multi-aircraft cooperation
