| Abstract: | Based on research status on zonal disintegration mechanism of deep surrounding rock. The influence of deep rock characteristic on roadway destruction and supporting is summarized, and the limitations of existing supporting load theory of deep rock engineering are discussed. The supporting method applicability for deep surrounding rock with zonal disintegration tendency is analyzed. Due to complex condition of physical and mechanical properties and geological environment in deep rock engineering, the concept of dynamic combined support is put forward. |

| Keywords: | zonal disintegration mechanism supporting load theory reinforcement dynamic combined support |
