The design of the tunnel blasting course is an important comprehensive practical teaching link of the "Blasting Engineering" course of related majors in colleges and universities. To explore new ideas for reforming teaching practice, given the challenges of complex calculations, difficult parameter selection, and cumbersome diagram drawing in traditional curriculum design, a tunnel blasting intelligent design software platform was proposed for course design. By integrating digital and intelligent design technologies, the authors develop an intelligent design platform that converts abstract blasting parameter design into a clear visual model. The platform includes four modules: blasting design, resource library, data management, and global settings. It innovatively realizes real-time modification of blasting parameters and implementability judgment, has a guided operation process, and forms an interactive teaching mode. The practical results demonstrate that the intelligent design platform effectively reduces the computational burden and the subjectivity of parameter selection for students in traditional teaching practices through the guided operation process, enhances drawing efficiency and accuracy, and ensures that the blasting design scheme is scientifically and reasonably formulated. The interactive teaching mode enhances students' ability to combine theory and practice, stimulates their interest in active learning, thereby improving their understanding of professional knowledge, cultivating intelligent design ideas, and providing support for becoming high-quality talents serving the new era.
