Traditional blasting engineering courses are limited by abstract theoretical concepts and limited experimental training. In order to address these challenges, this study developed a quasi-plane strain blasting experimental teaching system under confining pressure loading. We independently developed an integrated experimental device for cylindrical charge blasting. The device combines lateral constraint, high-speed photography, and ultra-dynamic strain testing; additionally, we combined digital image correlation full-field strain analysis with dynamic strain gauge point measurements. This methodology enables the visualized observation of blast-induced crack propagation and comprehensive data analysis of strain wave propagation patterns. Teaching practice demonstrated that the developed system, which employs a “teacher demonstration–student practice” hierarchical teaching model, enabled students to visually grasp blasting damage zone characteristics and stress wave attenuation laws. Thus, the system significantly enhances theoretical understanding and scientific research innovation capabilities; it provides a replicable practical paradigm to address the challenges of high safety risks and operational complexity in traditional blasting experiments.
