路堑洞室控制爆破技术设计

On controlled blasting technique of slope-cut chambers

以某高速公路路堑洞室控制爆破工程为例,从药包布置、药量计算、起爆网络三个方面介绍了主要爆破参数设计方法,并对爆破安全进行了检算,阐述了爆破方量与爆破所用的器材,达到了一次爆破成型的效果。

Taking the controlling blasting technique of slope-cut chambers of some expressway as the example, the paper introduces the main blasting parameter design methods from the allocation of explosive packages, calculation of explosive volume and detonating network, inspects the blasting safety, and illustrates the equipment used for the blasting amount and explosion, and it achieves the demanded effect in one time.
