Abstract: The air inlet pedestrian roadway at -890 m of Cixi Coal Mine has occurred serious deformation and destruction due to its poor engineering geological conditions，great horizontal tectonic stress and low self-supporting capacity.To control surrounding rocks deformation of the roadway and ensure its stability，the elastic-plastic analysis on deep high-stress roadway deformation and destruction under different yield criterion and conditions is carried out，and the yield criterion applicable to engineering practice is determined.Based on FLAC3D，combined with a lithological composition analysis and mechanical property test results of surrounding rocks，the supporting structures and parameters of different supporting schemes are contrasted and optimized，and a combined supporting scheme of bolting and shotcreting is proposed，with anchor bolts and cables as the core.Mine pressure after the excavation of roadways are monitored to verify the reliability of the supporting scheme further and obtain the characteristics of surrounding rock change after excavation.Engineering practice shows that the combined supporting scheme of bolting and shotcreting has a significant effect on improving the stability and integrity of deep highly stressed roadways，and makes the stress and deformation of surrounding rocks be more stable.It provides a strong technical support to ensure the long-term security and stability of coal mines.
