Tunnel blasting design is an important part of tunnel construction, and a reasonable blasting program can not only improve the construction efficiency, but also ensure the stability and safety of the surrounding rock. In this study, an intelligent design platform for tunnel blasting program is developed, which aims to solve the limitations of traditional blasting design methods under complex geological conditions. The platform is developed in JavaScript language, combined with React, Nest and other technologies to support efficient interaction and data processing between the front-end and the back-end. By designing an automated blasting parameter calculation module, the platform is able to automatically generate a blasting plan based on the specific parameters of the tunnel project (e.g., geological conditions, tunnel dimensions, etc.), and provide key contents such as the arrangement of the gun holes, the calculation of the charge amount, and the sequence of detonation. The unit consumption of explosives designed by the system is 0.96, which is lower than the 1.04 of the traditional design system, showing good optimization effect. In addition, on-site application verification shows that after adopting this system, the blasting effect is better than the traditional design, the over and under excavation is controlled within 12cm, and the utilization rate of the shell hole is increased to 86%. The application of this system not only improves the design efficiency, but also reduces the construction cost and resource consumption, which has a wide engineering application prospect.
