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(mian)利用水沙袋替代炮(pao)泥，以(yi)避免搗炮(pao)泥損毀電雷管導線，造成瞎炮(pao)。大(da)(da)大(da)(da)減(jian)少(shao)對圍(wei)巖擾動，光面(mian)效果好(hao)，巖性(xing)條件差情(qing)況下(xia)可以(yi)大(da)(da)大(da)(da)減(jian)少(shao)超挖量(liang)，控(kong)制(zhi)巷(xiang)道(dao)成型(xing)(xing)；巖性(xing)完整無節理情(qing)況下(xia)眼(yan)痕率可以(yi)達到(dao)90%以(yi)上(shang)，巷(xiang)道(dao)成型(xing)(xing)好(hao)，穩定性(xing)強。布孔(kong)方式優化成多排掏槽布孔(kong)，單次掘進深(shen)度(du)可以(yi)優化提高(gao)10%到(dao)15%不等。由于炮(pao)孔(kong)數量(liang)大(da)(da)大(da)(da)減(jian)少(shao)可以(yi)考(kao)慮一起(qi)全斷面(mian)起(qi)爆，節省放炮(pao)時間。
