Study on deformation law of roadway surrounding rock under dynamic disturbance

Meikuang Anquan
The surrounding rock is in a state of high stress during deep mining of coal mine, and the dynamic disturbance may lead to the instability of the surrounding rock and even rock burst. Therefore, it is of great significance to study the influencing factors of the deformation of roadway surrounding rock under dynamic disturbance.
