摘要：China's mine blasting technology is gradually mature, but there are deficiencies in low blasting efficiency. The reasonable matching of explosives and rocks can effectively improve the blasting efficiency and is of great significance for mine blasting. Based on ANSYA/LS-DYNA, the matching effects of rock physical density, elastic modulus, Poisson's ratio, compressive strength and shear modulus in double-hole blasting were studied and verified by simulation. By comparing the length of time that the shock wave caused the rock to be crushed, the experiment shows that the longer the blasting time, the better the matching effect. Numerical simulations show that the five physical factors affecting the matching effect of explosives and rocks are: compressive strength, Poisson's ratio, density, shear modulus, and elastic modulus. It has been verified that the experimental results can provide reference for the development of blasting technology.
