在我矿掘进爆破作业中,多年来沿用2~# 岩石炸药作柱状连续装药,一般效果尚好,但用于淋水工作面则较差,存在瞎炮多、处理不安全,炸药耗量大,直接影响掘进工效和进度等问题。经现场调查分析,认为主要原因是装药时,原装药卷的纸壳因与粗糙的炮眼内壁摩擦挤压而常破裂,水遂渗入药卷内导致产生瞎炮,另也和装药操作不当,起爆药卷加工不好,雷管爆力偏小等有
In mine excavation blasting operations, 2 # # rock explosives used for many years continuous columnar charge, the general effect is good, but for the pouring face is poor, there are more blind cannons, unsafe handling, large explosives consumption , A direct impact on driving efficiency and progress and other issues. The field investigation and analysis, that the main reason is that when the charge, the original drug roll of the shell due to rough and blasthole wall friction squeeze and often rupture, water and then into the drug volume resulting in blind artillery, the other and the improper handling of the charge , Detonated drug processing is not good, such as the detonator is too small
