| 摘 要： | 爆破飞石是造成大量工程事故的五大爆破危害之一,其飞散距离的估算存在较大难度,主要是因为确定爆破飞石飞散距离的因素很多。本文查阅了大量相关资料,总结得出了计算爆破飞石飞散距离的经验公式、统计规律公式、弹道公式和其他公式。从使用情况来看,几何相似公式的使用次数最多,但是该公式的系数K1的选取存在较大差异,取值范围大多为1~2;而该系数对计算结果有直接影响,需要广大爆破工作者进行相应的试验来细化K1的取值。

| Abstract: | Blasting flying rock is one of the five blasting hazards which brought about a large number of engineering accidents.We have so many difficulties in calculating the casting distance of blasting flying rock because the factors of it are much more.In this text,we have read a great deal papers and summarized some formula such as experience formula,statistics law formula,ballistic formula and so on.From the using,the geometry similarity formula has been most cited.However,the coefficient K1 of it had great diff... |
