Research on Vibration Characteristics of Precision Initiation in Longhole Bench Blasting
A initiation technique of digital detonator was employed in the test of precision initiation with longhole bench blasting operation, and vibration measurement was also conducted. Based on the analysis of site measured vibration waveform by blasting, the characteristics of blasting vibration was studied, the influence of vibration characteristics caused by the spatial location of blasting centre was discussed. A suggested value of reasonable stage interval for accurate initiation with Ionghole bench blasting operation was put forward.
