Abstract：Based on the geological conditions of a mine in Shanxi Province,FLAC3D numerical simulation software was used to analyze the influence mechanism of parameters such as mining depth,weak structural planes,and surrounding rock strength on the evolution law of zonal disintegration in roadway.The simulation results show that a high stress environment is a necessary mechanical condition for the occurrence of zonal disintegration in surrounding rock of deep roadways.The development and spatial distribution characteristics of weak structural planes inside the surrounding rock play a key role in the formation of zonal disintegration.Changes in the strength parameters of surrounding rock have a significant impact on the expansion range and degree of damage of disintegration zone.The research results provide theoretical and data support for revealing the formation principle of zonal disintegration of surrounding rock in deep roadways.
