定向断裂控制爆破理论分析及现场应用
Theory analysis of directional split of rock by controlled blasting and practical application
【摘要】 基于断裂动力学理论 ,文章论述了切缝药包定向断裂控制爆破炮孔间贯通裂纹形成的机理。按照切缝药包定向断裂控制爆破参数计算公式确定的炮孔间距和装药量 ,经现场实际应用证明是有效的和合理的。
【Abstract】 Based on the theory of dynamic fracture mechanics,the mechanism of crack-forming among shot holes in the directional split of rock by controlled blasting is expounded.Equations for calculation parameter of directional split of rock by controlled blasting are used to determine the hole spacing and explosive charge,it is effective and reasonable in practice.
