Abstract This paper presents the generating mechanism of blasting vibration and analyzes the hazards induced by the blasting vibration of urban underground works. It concludes eight kinds of technical measures for blasting vibration control, such as controlling the initialing charge per delay interval, a reasonable interval time of initiation, proper cut type, and non-explosive blasting based on the engineering practice. Ultimately, it points out that the selection of appropriate vibration control measures should be based on the specific conditions during blasting of urban underground works.
