專業多向聚能管是將炸藥裝在聚能管內，兩頭均放置了水袋，聚能管爆炸產生的高溫高壓射流，讓水袋產生“水楔”效應,使圍巖裂縫加劇延伸擴展。它是在水壓光面爆破基礎上發展起來的一項新技術，區別只是在周邊眼中安裝專用線性聚能藥管替代常規爆破藥卷和傳爆線，只要做到七大關鍵環節：水袋挺拔飽滿、炮泥軟硬適中、水袋裝填到底、炮泥回填到口、木棍逐節搗固、水藥緊密相連、槽面必須平行，就能對控制超欠挖起到良好效果。多向聚能管價格在(zai)推廣水壓爆(bao)破的基(ji)礎上(shang)，去年9月，水壓聚能爆(bao)破的成(cheng)果上(shang)，今年更為深入地(di)在(zai)興泉鐵(tie)路大嶺隧道(dao)(dao)、牡佳鐵(tie)路麻山隧道(dao)(dao)采用(yong)了(le)此項技術，積累了(le)成(cheng)功經驗。
