Abstract：Mining-induced mechanical behavior of rock depends on the changing stress state，which is different from the intrinsic mechanical behavior. The mining-induced mechanical triaxial test has been designed based on the distribution of stress state during the excavation. The characteristics of released energy in strain softening process have been discussed by the contrast between conventional and mining-induced mechanical triaxial test from theory-based view. Furthermore，the composition of energy storage induced from in-situ stress is discussed with result that the critical value of necessary energy for destruction is far less than the traditional results. It is reasonable to explain the mechanism on dynamic failure of coal or rock. And there is one from the new thinking of mechanism on outburst that at the shallow depth dynamic failure may also occur，which means that the high in-situ stress is the dominant factor of energy storage，also a necessary condition for dynamic failure but not sufficient condition.
