Abstract

Abstract

Being of a complex hierarchical structure with energy closed in it for its intrinsic friction and cohesion, the rock mass can be regarded as a medium with the properties of internal energy source and energy collection. The equivalent impact energy factor corresponding to the rock mass under high in situ stress subjected to the weak disturbance was presented, and the calculation method of the irreversible deformation region radius under the large-scale underground explosion was deduced. Compared with the method by Kocharyan G G, et al, the calculation method presented in this paper has a clearer physical principle and wider application.
- large-scale underground explosion,
- block hierarchy structure,
- equivalent average kinetic energy,
- local irreversible deformation
