| Abstract: | According to the theory of shock waves, the smash district and its forming time, the blasting cavity radius and its expanding characteristics are all discussed in this paper. The results show that the principal factors effecting the smash district and the blasting cavity radius are strength of the shock wave,the characteristics of rocks and radius of the hole. |
