预装药爆破技术在德兴铜矿的应用

Application of preload blasting technology in Dexing Copper Mine

对硫化矿预装药爆破技术进行了较为全面的研究,解决了硫化矿预装药的爆破安全问题,实现了大区微差爆破和多工作面同时起爆系统,减少了爆破次数,提高了大型生产设备的效率,经济效益和社会效益显著。

This paper makes relatively complete investigation on the preload blasting technology of sulphide ore, settles ihe problems of sulphide ore explosive-preload safety, realizes the short delay blasting in large region and simultaneous detonating system of multi-work faces, reduces the blasting times and improves productive efficiency of large equipment, economic benefit and social effect visibly.
