摘要(Abstract)：

利用集中药包的叠加原理,结合爆破效果研究端部等效集中装药与柱状装药的等效关系。假设柱状药包是由一系列集中药包组成,柱状药包对端部岩石的作用是由一系列等量的集中药包对端部作用叠加的结果,计算获得了端部等效集中装药药量。以集中装药药量为依据,确定井巷掘进爆破及台阶深孔爆破等柱状装药端部抵抗线及合理的填塞长度。
Relations between the end equivalent concentrated charge and column charge were studied by analyzing the concentrated charge superposition principle and the blasting effect.A columnar cartridge was supposed that composing of a series of concentrated charge,and the effect on the end rock was the result of superposition consisting of a series of the same amount of concentrated charge.The end equivalent concentrated charge was obtained through calculation.The end resistance line,reasonable filling length of drivage blasting and deep-hole blasting were determined based on the concentrated charge quantity.
