Deformation and Failure Characteristic of Roadway in Deep Mine

Aiming at the severe deformation and failure of the specific circumstances such as frequent roof fall and seriously spalling in deep mine roadway, based on the results of the theoretical analysis of deep roadway stress field distribution around and numerical simulation through FLAC^3D and filed data, this article studied the development process of deformation and failure of deep roadway, compared the process of the plastic zone of different original rock stress level, found that the location of the destruction of roadway move up with the depth increasing, pointed the failure characteristics of surrounding rock and measures to prevent the damage of surrounding rock affected by tectonic stress level of deep roadway.
