Abstract: To better measure the three dimensional mining induced stress of surrounding rock, and get more comprehensive changing status of the three dimensional stress tensor for surrounding rock of roadway excavation in the process of mining, in this paper, we use the theory of stress relief method to monitor mining stress, and carry out finite element simulation for the measurement point mining stress borehole measurement in the excavation of real roadway working face through ANSYS modeling. In this paper, the distribution of three-dimensional dynamic stress in the excavation of roadway excavation is obtained, and the theoretical model of stress release method is applied to measure the error of the stress and mining stress of the original rock. It is concluded that the stress distribution is different, the error is larger, and it has some regularity.
