分段爆破地震强度的试验研究
|
摘要
在爆破实验中,通过调整段数、分段炸药量、炸药总量、间隔时间、孔网参数、岩石波阻等爆破相关因素,以改变各分段爆破地震波持续时间、段别间爆破地震波重叠程度来研究爆破地震强度与爆破相关因素间的相互关系。阐明了爆破地震波传播规律及其破坏行为特征,以及各个爆破相关因素对爆破地震强度的影响程度。获得了确定段数等爆破参数的规则,从而为生产实践设计最佳爆破参数提供理论依据。
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.
