Abstract: Aiming at the complex and variable stress distribution of surrounding rock in inclined coal seam roadway and the poor effect of conventional support scheme, the theoretical research, numerical simulation and on-site monitoring method of roadway support technology were systematically studied in combination with the specific engineering background of Shitanjing No.2 mine.The results show that the vertical stress of the top and bottom of the right angle trapezoidal roadway in the inclined coal seam is inclined to the low side, and the horizontal stress is concentrated at the sharp corner of the roadway, which is particularly prominent at the sharp corners on both sides of the roof.According to this feature, a targeted asymmetric support scheme is proposed and numerical simulation analysis is carried out.The asymmetric distribution of surrounding rock stress is obviously improved after the support, and the deformation is greatly reduced.On-site implementation monitoring shows that the scheme can effectively control the asymmetric deformation and damage of the right angle trapezoidal roadway in inclined coal seam.According to the asymmetric distribution law of surrounding rock stress of roadway, the proposed supporting scheme plays an important role in the stability control of surrounding rock of inclined coal seam roadway.
