Blasting Powders Cooperated with Explosives
In order to reduce the production cost, reduce labor intensity and improve the quality of precious stone blocks, Design of a new charging structure applied to directional fracture controlled blasting. In the experiment, sulfur-free black powder used to replace the traditional black powder, and the preparation of the performance of sulfur-free black powder was tested to ensure that the sulfur-free black powder explosive performance and storage use in the process of security, but also reduce environmental pollution. Using slotted stress concentration, through cement mortar test block to simulate the synergistic Explosive blasting stone cutting in the blasting effect. Experimental results show that the design of Explosives common charge structure is reasonable and cooperative Explosives blasting method is feasible. Finally, through the process of analysis of the role of the combined effects of blast and explosion of gas theory, apply that collaborative Explosive Energy Explosive blasting can be made more rational use, to reduce the cost of stone mining ,improve the mining cycle, and improve the quality of the role of blocks.
