Deep-hole Blasting Vibration and Drop Shock Test and Analysis of Measures

Deep hole blasting method is employed in the construction of Xidayang reservoir,the blasting source is close to the private residence and reservoir dam.To guarantee safety,reduce the disturbance to residents,ascertain the maximum explosive amount per delay,reduce the blasting vibration,study the influence factors of blasting vibration,blasting vibration monitoring was carried during earlier period blasting construction of the project,the empirical formula of blasting seismic wave propagation was obtained for the project,then the reason of blasting vibration,the characteristic and propagation law of blasting seismic wave and the influence factors on blasting vibration were analyzed,which provides the basis for forecasting the intensity of blasting vibration and selecting vibration absorption method.
