摘要
通过理论和实验研究了切缝药包爆破机理和爆破参数，结果表明，切缝药包爆破有明显的聚能效应和护壁作用。其最佳装药不耦合系数为1．5～2．2。
Mechanism and parameters of cutting seam cartridge blasting were studied. It can be concluded that cutting seam cartridge blasting has a distinct energy cavity effect and protecting borehole wall effect and its optimum decouple coefficient is 1.5 ～ 2.2.
