Structural form and characteristic analysis of charge structure with deck decoupling

In order to study the structural form and application scope of blast holes charge and achieve the purpose of specific blasting effect, through a large number of engineering practice and investigation, the basic classification, functional characteristics and application scope of deck charge and decoupling charge are summarized. The selection principle of design parameters of common charge structure in open-pit deep hole blasting and tunnel excavation blasting is analyzed. It is discussed that in the construction process of controlled blasting the use of different charge structure can change the direction of explosive action, energy utilization rate and the action time of explosive generated gas;It is the main technical means to control the blasting hazard and improve the blasting effect. It has great practical significance to select, design and optimize the charge structure reasonably in the blasting engineering application.
