摘要

由于装药结构作为爆破设计的重要参数，对爆破影响不可忽视，由阻抗匹配角度对3种不同装药(耦合、空气不耦合及水不耦合)结构爆破能量传递进行理论分析，获得能量传递与装药结构关系，即不耦合装药时存在合理的不耦合系数使爆破能量高效传递给岩石。通过具体爆破开挖工程对爆破震动进行测试及能量传递公式验证，结果表明，以水作为不耦合介质的不耦合装药能有效降低爆破震动能量，减小爆破粉尘危害，且使块度更均匀。

Abstract

As an important parameter in designing blasting, charge structure has a significant impact on blasting. From the perspective of impedance matching, it carries out a theoretical analysis on blasting energy of three charge structures. With the relationship between the charge structure and energy transfer drawn, the study results indicate that there exists a reasonable decoupling coefficient when the charge structure is decoupled, thus allowing blast energy to transfer efficiently to the rock. Choosing the blasting excavation of Longwangshan in Zhejiang, this study tests the blasting vibration to verify the formula of energy transfer. Through comparative analysis on their corresponding explosive effects, it is concluded that decoupling charge with water as decoupling medium can effectively reduce the vibrating energy of blasting, producing more uniform fragment size and reducing dust pollution caused by the blasting.
