Abstract

Based on the pillar blasting recovery and goaf stability control of the 3–6# ore body of Baiyinnuoer lead-zinc mine, a HJC model of lead-zinc mine surrounding rock is established to simulate the safety and stability of this blasting project. To determine the parameters of the surrounding rock HJC model, through uniaxial compression tests, Brazilian splitting tests, ordinary triaxial isostatic tests, and SHPB Hopkinson tests were conducted. Subsequently, theoretical calculations and fitting were performed to ascertain HJC model parameters, including strength, damage, and pressure parameters. Utilizing LS-DYNA, modeling and numerical analysis were carried out based on the determined parameters. The obtained stress-strain curve was then compared and analyzed alongside the experimental results. The findings revealed that the simulation curve exhibited overall consistency with the experimental curve. Specifically, the fitting goodness R2 values were 0.865, 0.803, and 0.811 at impact pressures of 0.3MPa, 0.4MPa, and 0.5MPa, respectively, thereby validating the rationality of the determined HJC model parameters.
