專業深孔爆破聚能管光面爆破技術優勢：相對于傳統爆破工藝，聚能管光面爆破比常規爆破具有以下優勢∶少打眼，少裝藥。節約周邊鉆孔量50%，總鉆孔進尺減少30%；節約炸藥10～20%，雷管30%。節約噴漿料15-20%。節省時間∶每循環鉆孔、裝藥、噴漿時間1.5-2.0小時。深孔爆破聚能管價格在安全方面利用水沙袋替代炮泥(ni)，以(yi)避免搗炮泥(ni)損(sun)毀電雷管導線(xian)，造(zao)成(cheng)瞎(xia)炮。大大減少對圍(wei)巖擾動，光面效果好(hao)，巖性(xing)(xing)(xing)條件差情況下可(ke)以(yi)大大減少超(chao)挖量(liang)，控制巷(xiang)道成(cheng)型；巖性(xing)(xing)(xing)完(wan)整無(wu)節理情況下眼(yan)痕率可(ke)以(yi)達到90%以(yi)上，巷(xiang)道成(cheng)型好(hao)，穩定性(xing)(xing)(xing)強。布孔方式優化成(cheng)多(duo)排掏(tao)槽布孔，單次掘進深(shen)度(du)可(ke)以(yi)優化提高10%到15%不等。由于(yu)炮孔數量(liang)大大減少可(ke)以(yi)考慮一起全斷面起爆，節省放炮時間。
