摘　　要：通过对开拓巷道围岩松动状态、表面位移和压力监测分析,得出了开拓巷道围岩松动状态与承载性能的综合分析结果。分析开拓巷道围岩松动范围的演化规律和断面形式的选择,给出了开拓巷道合理支护结构形式。By analysis on the surrounding rock loose state, suriace displacement and the surrounding rock pressure monitoring, The comprehensive analysis results of surrounding rock loose state and bearing capacity of the developing roadway were obtained. The numerical simulation software was used for numerical analysis on the evolution of the loose range and tunnel section form selection, The reasonable supporting structures of the developing roadway were obtained.
