采用三维激光全息动光弹超动态综合测试系统进行了定向断裂爆破模型试验研究。分析和讨论了定向断裂爆破动应力场参数和定向断裂爆破作用机理；优选了实用的定向断裂爆破新方法和配套工艺。经岩巷生产实践表明：所选择的切缝药包定向断裂爆破方法是可行的，它为改革现有光面爆破技术提供了良好的应用前景。
Directional fracture blasting model test was carried out by using 3D laser holographic dynamic photoelastic hypersonic dynamic integrated test system. The dynamic stress field and directional fracture blasting mechanism of directional rupture blasting are analyzed and discussed. A new practical method of directional rupture blasting and its matching technology are optimized. The production practice of rock roadway shows that the selected method of directional fracture blasting of kerf packets is feasible and it provides a good prospect for the reform of existing smooth blasting technology.
