Over the years, a large number of scholars have done a lot of research on the active control of blasting earthquake hazards and blasting vibration hazards. Although some valuable results have been achieved and a series of vibration reduction measures have been summarized. However, with the increasing complexity of the blasting construction environment, the significant improvement of citizens' awareness of rights protection and the increasingly stringent standards for blasting vibration safety control, higher requirements have been put forward for the study of blasting earthquake effects and the control of blasting vibration hazards. In recent years, with the emergence of new blasting equipment and the development of blasting technology in the direction of refinement, experimental research on blasting vibration control technology based on high-precision digital electronic detonators or detonating cord detonators has become a trend.
