專用爆破多向聚能管預裂與光面爆破技術的歷史與現狀：預裂爆破是沿設計開挖邊界布置密集炮孔，采取不耦合裝藥或裝填低威力炸藥，在主爆區之前起爆，從而在爆區與保留區之間形成預裂縫，以減弱主爆破對保留巖體的破壞并形成平整輪廓面的爆破作業。爆破多向聚能管廠家光(guang)(guang)面(mian)(mian)爆(bao)(bao)(bao)(bao)破(po)是(shi)沿(yan)設計開挖邊(bian)界布設密集炮孔，采(cai)用(yong)不耦合裝藥或裝填低威力炸藥，在(zai)主爆(bao)(bao)(bao)(bao)區爆(bao)(bao)(bao)(bao)破(po)之(zhi)后(hou)起爆(bao)(bao)(bao)(bao)的(de)(de)以形成(cheng)平整的(de)(de)開挖輪廓(kuo)面(mian)(mian)的(de)(de)爆(bao)(bao)(bao)(bao)破(po)作(zuo)業。爆(bao)(bao)(bao)(bao)破(po)技術的(de)(de)發(fa)展是(shi)先出現(xian)光(guang)(guang)面(mian)(mian)爆(bao)(bao)(bao)(bao)破(po)，然(ran)后(hou)衍生(sheng)發(fa)展為預(yu)裂爆(bao)(bao)(bao)(bao)破(po)。聚(ju)能管(guan)國內歷史與現(xian)狀，我(wo)國于1964～1965年在(zai)湖北陸水水電(dian)站施工(gong)中做(zuo)過淺孔預(yu)裂爆(bao)(bao)(bao)(bao)破(po)試驗，1965年鐵道部門在(zai)成(cheng)昆鐵路(lu)建(jian)設中開始(shi)試驗光(guang)(guang)面(mian)(mian)爆(bao)(bao)(bao)(bao)破(po)，1977年在(zai)西延線張(zhang)家船工(gong)點(dian)，全(quan)長近200m的(de)(de)2000m2路(lu)塹邊(bian)坡全(quan)部采(cai)用(yong)光(guang)(guang)面(mian)(mian)爆(bao)(bao)(bao)(bao)破(po)，爆(bao)(bao)(bao)(bao)破(po)后(hou)邊(bian)坡平整穩定(ding)，殘留(liu)的(de)(de)半孔清(qing)晰可(ke)見，是(shi)鐵路(lu)建(jian)設中采(cai)用(yong)路(lu)塹光(guang)(guang)面(mian)(mian)爆(bao)(bao)(bao)(bao)破(po)。
