Abstract: The stability of the surrounding rock of the roadway is directly related to the safety and effi⁃ cient production of coal mines. In order to ensure the stability of the surrounding rock of the roadway，the 11012 working face of the Zhaogu No.2 Coal Mine in Jiaozuo Coalfield is used as the engineering back⁃ ground.By comprehensively using the means of field investigation，rock mechanics experiment，theoretical analysis industrial test and so on，the deformation and failure characteristics of the roof of the roadway in the area affected by the advance of the mining roadway are studied.A mechanical model with the overlying stratum-roof-coal pillar as a unified system is established.The mechanical criterion for tensile and shear failure of roadway surrounding rock roof is obtained.Based on the above discussion results，a technical scheme of grouting anchor cable support suitable for local geological conditions is proposed.After using grouting anchor cable support，the overall dynamic coupling control of high-strength and full-anchor-grout⁃ ing integration of the surrounding rock of the roadway is realized.

Key words: mining roadway, advance support, grouting anchor cable, surrounding rock stability
