Abstract :
In this paper, the damage tensor is calculated based on damage theory. And the condition of stress waves diffusing in wall rock is calculated by applying the analytic method of stress waves diffusing in anisotropic rock to wall rock. The horizontal and vertical diffusing curves in two kinds of wall rock are obtained.
