| Abstract: | Aiming at the small size karst cave developed horizontally near the blasthole during cylindrical charge,the blasting numerical simulation of the four working conditions is carried out by using Ansys/Ls-Dyna software,which is full of water or air,when water and air coexist and when there is no karst cave.By observing the effective stress cloud map distribution under different simulation conditions,the influence of the medium contained in the horizontal development cave near the blasthole on the propagation of explosion stress wave is revealed. |

| Keywords: | small size karst cave explosion stress wave stress concentration numerical simulation |
