深孔微差爆破起爆延时及相邻段炮孔跳段概率的计算

CALCULATIONS OF THE DELAY TIME AND OVERLAPPING PROBABILITIES OF ADJACENT DELAY INTERVALS DURING LONG-HOLE MILLISECOND BLASTS

炮孔跳段,使爆破的顺序发生混乱。这样,不但影响爆破效果,而且影响爆破的安全。本文以概率论的理论为基础,根据微差雷管的延时分布,阐述了炮孔的延时和误差以及相邻段炮孔跳段概率的计算方法,它比单纯计算雷管的跳段概率更符合实际情况。

Overlapping delay of charged holes will result in disordering of blasts and hence detriment to the safety in blasts as well as to thee quality of blasts. Based on the probability theory, the paper will elaborate the methods for Computing the delay time and error of charged holes and overlapping probabilities of two adjacent delays of charged holes according to the delay time distribution of millisecond blasting caps. This will better match the realistic production blasts than in the case of a mere calculation of overlapping delay probabilites of millisecond blasting caps.
