摘　　要：应用聚能爆炸射流穿透作用原理，对露天煤矿地下疏干滤水钢管进行聚能爆破切割试验．研究了聚能装药的合理几何形状；探讨了点聚能装药、直线聚能装药和内圆线型聚能装药爆炸穿透机理；研制了ＹＹＣ－３Ａ０Ｖ及ＹＹＣ－３Ａ０Ｃ型实心装药中心起爆的内圆线型爆破切割器，成功地爆炸切割了深埋地下的２１９和２７３疏干滤水钢管．In this paper the shaped charge were used to cut the underground filtering pipelines in Huolinhe Open pit Mine which focuses the blasting energy and forms an extremely high speed penetrating jet. Through experiments the optimal geometry of shaped charge was studied. The penetration mechanisms of three kinds of charges, such as dot shaped charge, line shaped charge and internal circle shaped charge, were also investigated and compared. The YYC 3A 0V type and YYC 3A 0C type blasting cutters with internal circle shaped charge and detonated at the center of charge were designed and made which can successfully cut the underground filtering pipelines of diameter 219 and 273 respectively.
