o型聚能管公司給大家介紹下爆破聚能管的技術原理∶炸藥爆炸產生的爆轟波通過聚能管的聚能槽，將炸藥的動能、勢能轉換成高壓、高速、高能的射流，切割演示成縫。專用o型聚能管射流在(zai)孔(kong)壁產(chan)生(sheng)射流壓(ya)力達7000MPa，巖石動載抗壓(ya)強度為200MPa，抗拉為1/8～1/10的抗壓(ya)強度，相鄰(lin)(lin)兩炮(pao)孔(kong)互為鄰(lin)(lin)空(kong)面(mian)，疊加后的壓(ya)縮波(bo)變為稀疏波(bo)，在(zai)兩炮(pao)眼連線上使巖石結(jie)構斷裂，形成裂紋。準靜態(tai)(tai)氣體膨脹，靜態(tai)(tai)壓(ya)力在(zai)兩炮(pao)孔(kong)最短連線兩側產(chan)生(sheng)拉力使巖石裂縫進一步擴展。根(gen)據(ju)爆破應力集中氣刃作用原則，爆破氣體沿裂縫進一步擴大貫通，拋落巖石。
