In order to effectively control the stability of the surrounding rocks of the 9104 intake airflow roadway, FLAC3D numerical simulation was used to analyze the stress distribution patterns of the surrounding rocks during mining and recovery mining of the working face. The results showed that the maximum deformation of the top and bottom plates and the two sides during the mining were 43 mm and 83 mm respectively, after the implementation of the high-strength high pre-stress support scheme, which ensured the stability of the surrounding rock of the tunnel.
