普朗铜矿井下聚矿槽拉槽爆破问题分析及处理
|
摘要
普朗铜矿在自然崩落法采矿聚矿槽爆破过程中,经常会产生悬顶、周边炮孔炸药没有完全起爆甚至有毫秒管雷管未起爆等现象,导致聚矿槽爆破不合格,严重影响安全生产,在分析其问题产生原因的基础上,有针对性提出了解决问题的措施,确保了矿山正常安全生产。
During the blasting process of ore accumulating tanks in Pulang copper mine,which was mined by the natural caving method,many phenomenons were often produced,such as suspended ceilings,and incomplete detonation of the explosives in the surrounding blast-holes or even no detonation of the millisecond tube ors.Those phenomenons would result in unqualified blasting of the ore accumulating tank,which seriously affected the safe production.On the basis of analyzing the causes of the problems,some measures to solve the problems were proposed pointedly,ensuring the normal and safe production of the mine.
