摘要

Rock blasting presents complex mechanical challenges, including wave propagation within rock media and dynamic fluid–solid coupling damage. This study integrates the lattice Boltzmann method (LBM) with the distinct lattice spring model (DLSM) to develop a dynamic LBM-DLSM coupling framework, enhanced through a multi-time-step algorithm and a new unit conversion strategy. The proposed method is first validated via wave propagation simulations, demonstrating its accuracy and effectiveness in capturing fluid–solid coupled wave behavior. Its capability for rock blasting analysis is further verified through comparison with experimental results, providing a reliable numerical tool for rock blasting analysis.
