摘　　要：通过对掏槽爆破的实验研究,利用火药和猛炸药的联合装药方式,改变了以往的单一装药结构,模拟实验的结果表明,联合协同装药结构与单一装药结构的掏槽效果有着显著的区别,前者的掏槽效果要优于后者;同时通过炸药水下的测试结果表明,改进以后的装药结构的冲击波峰值压力的持续时间明显提高,即联合装药的爆炸生成气体量要大于单一装药,为爆破工程上快速高效的掘进提供了理论依据。Through the experimental research of cut blasting, this paper puts forward that the joint charging way of gunpowder and high explosives is greatly diferent from the single charge structure, which not only has changed single charge structure in the past, but is better than the later as it is proved. At the same time, the results of underwater explosive test show that its peak pressure duration of the shock wave has increased significantly, that is, the generated gas quantity of explosion of the joint propellant is more than a single charge, which also provide the theoretical basis for the rapid and efficient tunneling of blasting engineer.
