摘要
飞石是引起爆破安全事故的主要因素研究了飞石产生的原因,通过实验和数据分析,推导出了飞石运动规律的计算公式,并给出了砖、混凝土的介质系数B的取值;对飞石进行了弹道分析,推出了飞石最大飞行距离的计算公式;最后给出了飞石的控制方法图1,表1。
Flyrock is the main factor resulting blasting accident. The reasons resulting flyrock are studied. In terms of experiment and data analysis,the formula of calculating the starting speed of flyrock is obtained,the coefficents of brick and concrete are given.With the theory of orbit,the means to calculating maximum flying distance is supplied.Effective measurements to control flyrock are discussed. 1fig.,1tab.,5refs.
