摘要
定向断裂爆破与普通光爆、预裂相比，爆破效果明显提高，爆破能量利用更为合理。文中根据爆破断裂的分形研究，阐述了控制断裂爆破改进周边成形质量。
Compared with the conventional smooth blast and presplit methods,the controlled fracture blast has better result,the blast energy of which is made more rational use of.According to the study on the blast crack by fractal analysis,the mechanism improving periphery appearance and increasing the utilized explosion energy ratio by the controlled fracture blast is presented.
