Abstract:Drilling-and-blasting remains the predominant method for metal mining in China, and blast simulation is the key to optimizing blast design. For years, the Chinese blasting-simulation community has relied heavily on foreign codes such as ANSYS/Autodyn and LS-DYNA, creating an urgent need for domestic alternatives. Based on single-hole blasting-crater tests in concrete, this paper presents the first systematic comparison between GalaxyEDS—a Chinese explicit-dynamics software—and the international commercial code Autodyn. The comparison evaluates their ability to reproduce the physical phenomena numerically and assesses the domestic software’s accuracy and suitability for mining applications. The results show that GalaxyEDS closely matches both experimental data and Autodyn predictions in crater morphology, bulging motion, and blasting action index, providing quantitative support for the engineering deployment of the domestic code.
