大冶有色金属公司丰山铜矿首次在南缘运用了导爆索孔串联起爆方法 ,效果良好。鉴于岩石性质复杂多变等特性 ,该矿南采工区改变传统的矿山炸药起爆方式。以往都是将导爆索放入孔底并联起爆 ,这样产生的爆轰波冲击过大 ,对巷道眉线破坏严重 ,增加了不安全隐患。导爆索孔口串联起 Daye Nonferrous Metal Company Fengshan Copper Mine for the first time in the southern margin of the detonating cord hole series detonating method, the effect is good. In view of the complex nature of the rock and other characteristics of the mining area to change the traditional South mining mining explosive detonation. In the past, the detonating cord was put into the bottom of the hole and detonated in parallel. The impact of the detonation wave thus produced was too large, causing serious damage to the eyebrow line of the roadway and increased the unsafe hidden danger. Detonating cable orifice in series
