Abstract: According to the actual situation of the poor blasting effects of Qianbixi copper mine, the blasting explosive,blasting construction, the utilization rate of perforation,the shape of roadway are researched. The explosive consumption is reduced to 1.51 kg/m3, the average penetration of shallow hole blasting of working faces is increased from 2.6 m to 3.2 m, the blasting efficiency is increased to 91.4% by adopting the on-sit mixed charging emulsion explosive to conduct high effective smooth blasting. The research results show that, the blasting quality reach to the quality standard, perfect comprehensive benefits is obtained, besides that, the research results in this paper can provide some reference for mine construction.

Key words: On-site mixed charging emulsion explosive, High effective smooth blasting, Blasting construction
