信陽深孔爆破多向聚能管的軍事應用：聚能爆破技術，早在二次世界大戰期間就在軍事方面廣泛應用。國內在聚能破甲技術如大錐角反艦導彈戰斗部和大錐角反坦克地雷以及敏感彈戰斗部等方面取得了較為快速的發展，我國20世紀60年代打破國外技術封鎖獨立自主研發成功原子彈就是得力于聚能爆破技術轟擊核裝置而引爆原子彈。專用深孔爆破多向聚能管的民爆(bao)(bao)應用(yong)——切(qie)槽(cao)爆(bao)(bao)破技(ji)術(shu)：聚(ju)能爆(bao)(bao)破用(yong)于工(gong)程建設(she)也是(shi)20世紀60年(nian)代(dai)開始(shi)的，首(shou)先是(shi)瑞典的U﹒Langefors提(ti)出孔壁切(qie)槽(cao)爆(bao)(bao)破利用(yong)槽(cao)口(kou)應力(li)集中定向(xiang)開裂的設(she)想(xiang)，后經W﹒L﹒Fourney驗證是(shi)有效的。70年(nian)代(dai)國(guo)外(wai)廣泛(fan)研究和應用(yong)了切(qie)槽(cao)爆(bao)(bao)破技(ji)術(shu)。
