Abstract

TrueGrid and LS-DYNA are used to study water pressure blasting, and a shallow borehole blasting rock model is established. The influence of water in the borehole on the rock blasting effect is analyzed by damage coefficient cloud map and stress-time diagram. The results show that adding water to the borehole can increase the degree of rock breakage and reduce the cost of rock blasting effectively.
