Abstract Traditional blasting design methods relying on empirical approaches often suffer from low efficiency and inadequate precision. To overcome these limitations, an automated blasting design method was developed based on theoretical calculations and mathematical modeling. By developing algorithms for automatic layout of cut holes, auxiliary holes, and perimeter holes, coupled with optimization of charge structures and initiation sequences, the proposed method achieved automated blasting scheme generation, diagram output, and 3D visualization. The proposed method was validated in a practical rock shaft engineering project, where excellent wall smoothness and rock fragmentation effects were achieved. The results confirmed the feasibility of the automated blasting design, providing a scientific and efficient technical solution for blasting design challenges.
