Abstract：In order to achieve intelligent mining of large angle coal seam fully mechanized mining faces and solve the prominent problems of outdated mining equipment automation technology and difficult equipment matching in mines in southwestern China,the current application status of intelligent mining technology in fully mechanized mining faces at home and abroad was analyzed,and the difficulties in intelligent mining conditions of large angle coal seams were pointed out.The development of intelligent mining of large angle coal seams will inevitably be achieved in stages and gradually.Key technologies such as the layout of complete sets of equipment for intelligent working faces in high angle coal seams,automatic attitude control technology for center distance management of hydraulic supports,automatic roof connection technology for hydraulic supports,automatic control technology for anti overturning and anti-slip of hydraulic supports and scraper conveyors,and intelligent all-round coal gangue and personnel protection technology were emphasized.The feasibility of key technologies for intelligent mining in high angle coal seams was verified through industrial practice,providing technical support for intelligent mining in high angle coal seams.
