Abstract

The seismic effects produced by the daily step deep-hole blasting of the Open-pit mine were monitored by using the UBOX-20016 blasting vibration recorder.The empirical equation of the blasting seismic wave attenuation was deduced by the least square method through the data regression analysis,and its credibility is demonstrated.The technical measures of the controlled blasting vibration velocity in different blasting region,and the technical measures under the different blasting parameters and charging conditions are presented in this paper.
