介绍了钻孔装药台阶爆破时岩石块度组成的分析方法。该方法以破碎区的范围和岩体天然节理含量为根据,根据爆破岩石的物理力学性质及所使用炸药的理化性能计算破碎区的半径。通过爆炸应力波的反射作用,论证了岩体中因爆破膨胀应力波的作用而受破坏的比例。
The analysis method of rock mass composition during drilling charge blasting is introduced. Based on the range of the crushing zone and the natural joint content of the rock mass, the method calculates the radius of the crushing zone according to the physical and mechanical properties of the blasting rock and the physical and chemical properties of the explosive used. Through the reflection of the explosion stress wave, the proportion of damaged rock mass in blasting due to the explosion stress wave is demonstrated.
