Application and Optimization Design of Cooperation of Blasting and Explosive Model in Sulphide Mine

The mine economic benefit was closely related to blasting effect,then reducing blasting cost and improving blasting effect were important factors for reducing general cost of ore-exploitation. The cooperation model of blasting and explosive technique was based on the joint optimization of explosive characteristics and blasting technology. Firstly,the characteristics of explosive was optimized to fit the case of high sulfur-ore mining,and then the match effect between rock and explosive should be studied by orthogonal experiments. Finally,the optimal blasting parameters by using the optimized and appropriate explosive were studied.
