Due to the fact that, with the surrounding rock and support constituting a complex bearing system, the surrounding rock partition fracture, rock burst and other problems in deep rock mass caused by excavation will bring great potential safety hazards to the site during the construction of deep stratum tunnels. Taking the abnormal phenomenon of zonal fracturing as the research focus, an abnormal response characteristic model has thus been established under the special environment of high temperature, high ground stress, etc. of the deep roadway rock mass, relying on the actual project of a deep roadway in Huainan mining area, and with the help of FLAC3D numerical simulation software, followed by an analysis of the influence of different original rock pressure and internal friction angle on the zonal fracturing. The results show that different original rock pressures and internal friction angles have significant effects on the zonal fracture of surrounding rocks. When the original rock pressure gradually increases within the range of 17.3 MPa and 35.0 MPa, the volume of the interval rupture area increases from 0 to 25×102 m3; when the friction angle gradually increases within the range of 22°and 38°, the volume of the interval rupture area decreases from 26.87×102 m3 to 0, returning to the traditional failure mode of the shallow tunnel.
