Abstract：The disturbed stress field in deep mine roadway is closely related to the occurrence of excavation disturbed zone(EDZ). However，the geological conditions of site and the limitation of technology restrict the feasibility of in-situ monitoring to the disturbed stress field in deep mine roadway. Thus，the evolution of EDZ was instead obtained with the in situ monitoring firstly. Secondly，a numerical model was established by back analysis. The model is used to simulate the evolution of EDZ accurately. Finally，the evolution of disturbed stress field during the excavation of deep mine roadway was analyzed with this model. The results showed that the stress values of monitoring spots were not changed basically when the monitoring section was ahead of excavation plane due to the constraining of the rock in front of the excavation plane. When the excavation plane passed the monitoring section，the values and orientations of the principle stresses on the side，roof and floor were changed. The evolution of disturbed stress and EDZ were compared and found that they had some similar characteristics.
