Abstract: Blasting is one of the four technologies in mining engineering, Drilling and blasting cost takes a great proportion in the mining cost. Therefore, to long for an ideal blasting effect and to realize the optimal matching of blasting parameters have long been the core of blasting operation with real engineering as the case and based on Orica's hole-by-hole detonation technique, the paper describes in detail the program and contents of the optimization of blasting parameters and pointes out that Orica Co's high precision fuse blasting cap is a guarantee for realizing a hole-by-hole detonation and improving the blasting effect.

Key words: Blasting technology, High precision fuse blasting cap, Hole-by-hole technique
