为研究岩石破碎过程中爆炸应力波与爆生气体膨胀的作用，进行了耦合装药爆破实验。结果表明，耦合装药爆破时爆炸冲击能（Ｅｓ）和部分膨胀能（Ｅｂ）进行冲击加载，在介质中依次激起原生和次生爆炸应力波。不同Ｅｓ／Ｅｂ比值条件下，介质爆破致裂效果与破碎质量出现明显差异的主要原因，是这两个应力波加载水平发生了变化，进而影响到介质的爆破破裂行为。由此认为，Ｅｓ和部分Ｅｂ在破岩过程中所起的主要作用，是通过应力波与缺陷相互作用使岩石产生破裂的方式进行的；以（准）静态形式存在的部分Ｅｂ的主要作用，是促使爆破块度与岩体分离。
In order to study the effect of explosive stress wave and explosive gas expansion during rock fragmentation, coupling charge blasting experiment was carried out. The results show that the explosive impact energy (Es) and part of the expansion energy (Eb) are impacted by the explosive charge, and the primary and secondary explosion stress waves are excited in turn in the medium. Under different Es / Eb ratio conditions, the main reason for the significant difference between the fracture effect and the crushing quality of medium blasting is that the loading level of these two stress waves has changed, which in turn affects the blasting behavior of the medium. Therefore, it is considered that the main role played by Es and part of Eb in rock breaking is that the rock is ruptured through the interaction of stress waves and defects; the main function of part of Eb existing in quasi-static form, Is to promote the block and blasting blasting separation.
