抗水性高精度导爆管雷管在曼家寨采场的应用
|
摘要
云南华联锌铟股份有限公司曼家寨采场,采矿量210万吨的生产能力,现有的爆破质量很难满足电铲的铲装要求,曼家寨主要以普通导爆毫秒雷管加起爆弹作为起爆手段,但由于普通的导爆管毫秒雷管强度较低,在装药过程中容易因外界因素的影响,使整个网络的安全性降低,爆破效果难以控制,公司引进抗水高精度导爆管,经过试验,抗水高精度导爆管能够满足现场进行装药的要求,其安全性能提高,且能实现逐孔起爆技术,减少同段起爆药量,降低爆破震动,提高起爆网路延时合理性及准确性,提高爆破效果。
Yunnan Hualian Zinc Indium Co., Ltd. Manjiazhai stope,the mining capacity of 2.1 million tons of production capacity, the present blasting quality is difficult to meet the shovel requirements, Manzhai mainly detonated detonator as the detonation means, but because the ordinary detonator millisecond detonator strength is low, it is easy affected by external factors in the charging process so that the entire network security and blasting effect is difficult to control, the company introduced high-precision guide Bursting, after testing, high-precision anti-water detonation tube is able to meet the requirements of charge in site, it not only can achieve hole-by-hole detonation technology and reduce the same section of the detonation dose, but also weaken blasting vibration, improve the delay the rationality and accuracy and the blasting effect.
