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3.2m,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。
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 re- searched. 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 bene- fits is obtained, besides that, the research results in this paper can provide some reference for mine con- struction.
