深孔爆破聚能管價格聚能藥包破碎法特點是:不需要打眼，因而不需要購買打眼設備和動力設備;施工簡單，施工進度比淺眼爆破法快安全性比普通淺眼爆破法和普通裸露藥包法好;勞動強度比淺眼爆破法低。深孔爆破聚能管價格制造(zao)聚(ju)能(neng)(neng)藥(yao)(yao)(yao)包(bao)所采用(yong)的(de)(de)炸藥(yao)(yao)(yao)有(you):黑(hei)索(suo)金和(he)梯恩(en)梯混(hun)合熔鑄型(xing);乳化油炸藥(yao)(yao)(yao)和(he)黑(hei)索(suo)金混(hun)裝型(xing)和(he)二號巖石硝鉸炸藥(yao)(yao)(yao)壓制型(xing)。根據使用(yong)的(de)(de)結果證明，選用(yong)密度較(jiao)大和(he)爆速較(jiao)高的(de)(de)炸藥(yao)(yao)(yao)制造(zao)聚(ju)能(neng)(neng)藥(yao)(yao)(yao)包(bao)能(neng)(neng)獲得較(jiao)好的(de)(de)破碎效果。這主要是由于它加(jia)(jia)工簡單和(he)破碎能(neng)(neng)力較(jiao)大。在(zai)礦(kuang)山由于二次(ci)破碎消耗(hao)的(de)(de)藥(yao)(yao)(yao)包(bao)較(jiao)多(duo)，而且(qie)金屬藥(yao)(yao)(yao)型(xing)罩的(de)(de)加(jia)(jia)工費工又費材料(liao)，所以多(duo)不采用(yong)藥(yao)(yao)(yao)型(xing)罩。國(guo)內生產(chan)的(de)(de)一種用(yong)于破碎大塊的(de)(de)聚(ju)能(neng)(neng)藥(yao)(yao)(yao)包(bao)，裝置聚(ju)能(neng)(neng)藥(yao)(yao)(yao)包(bao)時，要將藥(yao)(yao)(yao)包(bao)垂直(zhi)裝在(zai)大塊的(de)(de)頂(ding)面上，聚(ju)能(neng)(neng)穴朝下。藥(yao)(yao)(yao)包(bao)位置應選在(zai)頂(ding)面的(de)(de)幾何中心或(huo)附近(jin)較(jiao)平整的(de)(de)地點。然后(hou)在(zai)上面覆蓋泥沙(sha)。

給大家介紹下爆破聚能(neng)(neng)(neng)管(guan)的(de)技術原理∶炸(zha)藥(yao)爆炸(zha)產生的(de)爆轟波(bo)通過聚能(neng)(neng)(neng)管(guan)的(de)聚能(neng)(neng)(neng)槽，將炸(zha)藥(yao)的(de)動(dong)能(neng)(neng)(neng)、勢能(neng)(neng)(neng)轉換成(cheng)高壓(ya)(ya)、高速、高能(neng)(neng)(neng)的(de)射(she)流，切割(ge)演(yan)示成(cheng)縫(feng)。射(she)流在(zai)孔壁產生射(she)流壓(ya)(ya)力(li)達7000MPa，巖(yan)石(shi)(shi)動(dong)載抗壓(ya)(ya)強度(du)為200MPa，抗拉為1/8～1/10的(de)抗壓(ya)(ya)強度(du)，相鄰兩炮(pao)孔互為鄰空面(mian)，疊(die)加后(hou)的(de)壓(ya)(ya)縮波(bo)變為稀疏(shu)波(bo)，在(zai)兩炮(pao)眼連線上使巖(yan)石(shi)(shi)結(jie)構斷(duan)裂，形(xing)成(cheng)裂紋。準靜態氣(qi)體膨(peng)脹，靜態壓(ya)(ya)力(li)在(zai)兩炮(pao)孔最短連線兩側產生拉力(li)使巖(yan)石(shi)(shi)裂縫(feng)進(jin)一(yi)步擴展。根據爆破應力(li)集中氣(qi)刃作用原則，爆破氣(qi)體沿裂縫(feng)進(jin)一(yi)步擴大貫通，拋落巖(yan)石(shi)(shi)。
