摘要
文章依据断裂力学理论 ,论述岩石定向断裂控制爆破炮孔间贯通裂纹形成的原理 ;分析岩石中固有裂纹大小对炮孔装药量和炮孔间距的影响 ;同是提出爆破参数的设计原则和方法。
Based on the theory of fracture mechanics,the mechanism of crack-forming among shotholes in the directional split of rock by controlled blasting is expunded. The effect of the length of existed crack in rock on the explosive charge and hole spacing is analyzed and the design principle and method for blasting parameters are also suggested. [
