Abstract ：Based on the coal seam condition and fully mechanized mining automation technology development status ，the

restriction factors and technical bottleneck of intelligent mining technology for three －soft seam of deep coal mine was analyzed．In order to solve the problems of coal wall spalling and roof leakage in three －soft coal seam ，an intelligent adaptive control strategy of hydraulic support based on multi －parameter monitoring and fusion analysis was proposed．Through analyzing the technical bottleneck of precise positioning and intelligent height controlling of the shearer ，the resourceful coal mining energy regulation strategy based on geological information advanced detection and interface recognition of coal and rock was proposed．The reasons for the abnormal working conditions of the scraper conveyor was analyzed ，and the early warning and control strategies for the abnormal working conditions based on the intelligent three －way attitude monitoring of the scraper conveyor was put forward．Aiming at the difficulty of realizing intelligent propulsion in advance support area of fully mechanized mining face ，unit intelligent adaptive advance hydraulic support and automatic moving device were studied ，which improved the adaptability and intelligent control level of advance hydraulic support for large deformation roadway．The intelligent cooperative promotion strategy of fully mechanized mining equipment group was analyzed ，and the development direction of intelligent mining technology of fully mechanized mining face was predicted．
