Abstract: Through the analysis of the instability mechanism, mining effect, physicochemical property of surrounding rock and floor failure characteristics of original U shape shed support of 1110 air-return way in the Xiayukou Coal Mine, the main reason which caused the unstable failure of surrounding rock is obtained. According to structure compensation principle, high stress broken seam tunnel shed-cable collaborative support technology is proposed. Through the test of deformation information of surrounding rock mass, it proves that this support technology effectively controls the surrounding rock mass deformation of tunnel.
