rock blasting explosive

基本解释

The effect of blasting on the rock medium is composed of the dynamical pressure of explosive shock wave and quasi-static pressure of explosive gas.
爆炸荷载对爆破介质的作用是由爆炸冲击波的动态作用和爆轰气体的准静态压力作用两部分组成。
The difficult is that the formation of blasting fragmentation was controlled doubly by rock characters, which involves the joint and crack, explosive characters and blasting parameters.
其难点在于爆破碎块的形成受岩体内宏观节理、裂隙、断层等地质结构（构造）和爆破参数、炸药参数的双重控制。
Based on this, the explosive type that matched the ore rock conditions was determined and the basis for selecting the related parameters of the test of shaft excavation by one blasting was obtained.
据此确定了与矿岩条件相匹配的炸药类型，得到了试验地段一次爆破成井试验的相关参数选取依据。
