Abstract: In order to solve the problem that the layout of the mining roadway caused by the three working faces of the original design of the east wing mining area II104 of the Luling Mine is difficult, the moving is frequent, and the continuous length of the fully mechanized mining face is short, using numerical simulation and field observation, and based on the original conditions of the coal seams in the II104 East Wing mining area and the characteristics of the roadway layout, the three working faces of the original design were combined into a II1041 working face.The key technology for the fully mechanized large-angle rotary mining plan, the process parameters and the rotating technology requirements, and the mining pressure law were studied combined with numerical simulation.The research was carried out to analyze the variation law of mining stress in the whole stope, and the method of controlling the up and down movement of the conveyor during the rotation of the II1041 working face and the control of the rotation angle of the bracket was put forward.The research results show that: with an adoption ratio of 1∶8, after 54 cycles, a total of 74° roration is completed.The maximum working resistance of the bracket during rotation is 6 481 kN/frame, and there is still a surplus of 4.7%.This has ensured the normal recovery of the working face.
