This study reviews the research progress and limitations of the safety standard system for blasting vibration in China to promote standard optimization and technological development. The core provisions of existing national standards and major industrial standards in water conservancy, railway, mining, and municipal engineering, with emphasis on major differences in vibration limits for various protected objects. Recent research progress was also reviewed regarding blast vibration propagation, safety criteria, structural response, intelligent prediction and vibration reduction technologies. Results show that the current standard system is limited in overlapping provisions, conflicting limits, and insufficient coverage of special geological conditions and emerging structural types. It is still dominated by static single-parameter control, posing deficiencies in frequency-velocity coupling framework and cumulative damage assessment. Despite significant advances in numerical simulation, machine learning prediction and electronic detonator precise delay technology, it is limited in the implementation of these research outcomes and insufficient validations. In this light, this study proposes the restructuring of the standard system into a "general basic + industry-specific" architecture by introducing dynamic, multi-parameter coupled control and intelligent monitoring systems to promote bidirectional translation among research, standards, engineering applications and enhance international alignment. This study provides references for the refined revision of blast vibration control standards and their engineering applications.

In order to solve the problem of poor overall blasting effect when using pre-splitting blasting technology in Beiya gold mine, based on RHT damage constitutive model, numerical simulation research on pre-splitting blasting under different hole spacings was carried out by using ANSYS/LS-DYNA numerical simulation software. The results show that when the hole spacing of pre-splitting hole is set to 120 cm, the crack between holes has obvious bifurcation and the crack propagation range is large. When the hole spacing is set to 130 cm, the crack propagation range decreases within the surrounding area, and the rock damage around the blast hole is obviously reduced. When the hole spacing is further increased to 140 cm, it is found that the cracks on the connecting line of adjacent pre-splitting holes are only locally connected and cannot penetrate through holes. It shows that the 130 cm hole spacing has reached an ideal balance between reducing the disturbance of the pre-splitting blasting itself to the rock mass and achieving effective blasting. Based on the results of numerical simulation, the site test has achieved good blasting effect. The research results can provide reference for the design and construction of pre-splitting blasting in similar mines.
