Abstract

Blasting cut size and blasting parameters are both key influencing factors in the process of chimney collapse. In order to verify the influence of its chimney collapse process, according to the empirical formula of blasting engineering parameters, the blasting notch form and blasting parameter values are designed, and the chimney is numerically simulated by ANSYS software, and the simulation results are obtained. The stress change diagram, the time change curve diagram of the coordinates of the node at the top of the chimney and the time change curve diagram of the velocity during the collapse of the chimney are analyzed, and the simulation results are basically consistent with the actual situation. This numerical simulation design method improves the scientificity of blasting scheme design.
