深孔爆破时,地震波、空气冲击波、飞石的危害范围比大规模的洞室爆破要小。但是深孔爆破,如果参数不当也会产生严重的飞石事故。而飞石距离的计算,用集中药包的公式计算时,爆破作用指数n值难以计算和确定,即使根据深孔药量计算了爆破作用指数,计算的飞石距离偏高得多。为此,本文根据实践过程中测得的大量数据,谈谈深孔爆破飞石距离的计算。
Deep-hole blasting, seismic waves, air shock wave, flying stone damage than the larger chamber blasting to be small. However, deep-hole blasting, if the parameters are not properly produced will have a serious flying stone accident. The calculation of the distance between fly-stones and the formula of the concentrated medicine bag makes it difficult to calculate and determine the value of n for the blasting effect index. Even though the blasting action index is calculated according to the amount of deep-hole medicine, the calculated fly-stone distance is much higher. To this end, this article based on a large number of data measured in practice, talk about the calculation of deep-hole blasting rock fly distance.
