Abstract：Based on the relationship of the local failure and impact energy factor on the high-speed impact，the theory of energy equivalence and its formulation for average vibration of deep rock mass disturbed by excavation or explosion are first proposed in this paper. The physical foundation of the non-dimensional energy condition that quasi-resonance and pendulum-type waves occurring is interpreted，and the condition is defined as the ground shock energy factor in this paper. The occurring conditions for engineering disasters such as rock burst and zonal disintegration are derived using this theory. Also，the safety depth of protective engineering is defined by the theory combined with propagation laws of underground blasting waves. The research shows that the ground shock energy factor reveals a new way for understanding the complex mechanism of the static and dynamic phenomenon for deep rock mass.
