自我们提倡用积分法计算爆破网路以来,一些矿山有关人员来信询问用双曲函数计算爆破网路的来龙去脉、应用范围及推导过程等。现特写本文予以介绍。一、两种不同的并联并联爆破网路有两种,一种是簇联(图1a),另一种是用连接线把雷管并联起来(图1b),后种形状如木梯,故称梯格并联。由于连接线有电阻,两种并联效果不一样。在采矿大爆破和竖井掘进时,经常采用梯格并联爆破网路。
Since we advocated using the integral method to calculate the burst network, a number of mine officials wrote to ask about the ins and outs of using the hyperbolic function to calculate the burst network, the scope of application and the derivation process. Now closeup of this article to be introduced. First, there are two different types of parallel parallel network explosion burst, one is the cluster (Figure 1a), the other is connected to the detonator in parallel (Figure 1b), after the kind of shape such as wooden ladder, it said Ladder parallel. Due to the resistance of the cable, the two parallel effect is not the same. In mining large-scale blasting and shaft excavation, the grid is often used in parallel to burst the network.
