Abstract：To address the complex environment,redundant construction processes,low degree of automation,slow excavation speed,high labor intensity of workers,poor safety,and poor coordination among excavation,support,transportation and other links in coal mine underground excavation working face,the supporting process and technology of coal mine intelligent excavation equipment was studied.The main influencing factors of excavation work face were expounded,and the three main cutting trajectory paths of boom roadheader,namely"snake""loop"and"spiral",were analyzed.The overall supporting scheme of intelligent excavation equipment,including"excavation+support+transportation+dust removal+water exploration+intelligent control"was introduced.The key technologies such as autonomous positioning and orientation technology of roadheader,automatic cutting and tunneling technology,adaptive cutting technology,working condition monitoring and fault diagnosis technology,and working face security warning and remote visualization technology were studied.Engineering applications showed that,the intelligent tunneling equipment solution led by the boom roadheade improved the efficiency of tunneling,reduced the labor intensity of workers,improved the working environment of the excavation face,and achieved automated and intelligent production operations such as excavation,support,transportation,dust removal,water exploration,and remote control.The efficient collaborative operation of the tunneling production system and the matching of production capacity achieved good application effects and alleviated the contradiction of imbalanced mining-tunneling ratios in coal mines.
