The Analysis of the Stress Field and Crack of Rock under the Blast Loading

Abstract:

The crack tip stress field of rock is analyzed under blast loading, and the crack arrest criterion, the conditions of rock crack initiation and crack extension are presented in this paper. The study will help the design of maintaining the stability of stope drift active workings.
