Title: RESEARCH AND APPLICATION OF BLASTING VIBRATION FREQUENCY CONTROL TECHNOLOGY
Abstract: Using the control theory of mechanical vibration to study the characteristics of blast spectrum,it was found that the earthquake occurred in delay blasting was caused by the superposition of rock blasting vibration and delay time vibration which were in the different spectrum.The rock blasting oscillating wave was transformed into harmonic wave to analyze by setting the delay explosion oscillating wave as the command fundamental wave,on this base,using the Doppler effect caused by floating epicenter,the mixed frequency was finally synthesized to achieve the frequency shift.According to these,fundamental theory and design methodology of the blast vibration dynamical response control were established and the theory and methodology were successfully applied into geotechnical blasting and demolition blasting.
