Experimental study on impact failure characteristics of deep circular roadway

Meikuang Anquan
In order to study the impact failure characteristics of deep circular roadway under the condition of disturbance load, based on the self-developed multi-functional physical simulation test system of rock burst, the impact failure test of circular roadway was carried out for large-scale rock-like materials.
