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.
