Abstract

Abstract

In blasting experiments, durations of subordinate basting seismic waves and intensity of influence among them are changed by adjusting the number of subordinate blasting, explosive weigh of subordinate blasting, total quantum of explosive, interval, hole-net parameters and wave resistance of rock, etc. Relation of blasting seismic intensity and related blasting parameters is researched to illustrate propagation law and damage performance of the blasting seismic wave, and influence extent of related blasting factors on blasting seismic intensity. The rule to determine the basting parameters is obtained to provide a theoretical foundation for the optimal design of the blasting parameters in productive practices.
