摘要/Abstract

摘要： 针对谦比希铜矿采掘爆破作业效果不理想的实际情况，开展了对爆破炸药、爆破施工、炮眼利用率、巷道成型等主要问题的研究。通过采用现场混装乳化炸药高效光面爆破，使得该铜矿炸药消耗量降低到1.51 kg/m3，工作面浅孔爆破的平均进尺由原来2.6 m增加到目前的3.2 m，爆破效率提高到了91.4%，爆破质量达到了优良标准，取得了良好的综合效益，对矿山施工具有一定的参考价值。

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
