Experimental studies on subordinate blasting seismic intensity

ZHANG Dan~(1),DUAN Heng-jian~(2),ZENG Fu-hong~(2)(1.Civil Engineering Faculty Southwest Communication University, Chengdu610031,Sichuan,China;2.Sichuanhuidong Lead-Zinc Mine,Huidong615205,Sichuan,China)  
In this paper,blasting relative factors in blasting experiments,including the number of subordinate blasting,explosive weigh of subordinate blasting,quantum of explosive,interval,hole-net parameters and wave` s resistance of rock,are adjusted,with result that durations of subordinate bastings seismic waves and intensity of influence among them,are changed so as to research the relation between blasting vibration intensity and blasting relative factors,so the blasting seismic propagation's regularity,its damaging characters and the effects of every blasting relative factor on blasting seismic intensity are elucidated.Further,the rules are drawn that blasting parameters, such as the number of subordinate blasting and so on,are ascertained,so that it is proved the theory to design the optimal blasting parameters in productive practices.
