各種爆破、爆破器材銷毀以及爆破器材意外爆炸時，爆破源與人員和其他保護對象之間的安全距離稱為爆破安全距離。爆破安全距離應取各種爆破效應（地震、沖擊波、飛石、有毒氣體等）分別核定的大值。專業深孔爆破多向聚能管爆破時，必然產生爆破地震、空氣沖擊波、碎石飛散及有害氣體，因此，爆破設計時必須確定爆破危害范圍，并確定爆點到附近人員、設備、建筑物及井巷等的安全，這一段距離就稱為爆破安全距離。專業深孔爆破多向聚能管如何控制好(hao)這(zhe)段距(ju)(ju)離就顯的(de)尤為重要。為保(bao)證爆(bao)破(po)(po)(po)安(an)全(quan)(quan)，爆(bao)破(po)(po)(po)地點(dian)與人員或(huo)其(qi)他(ta)應(ying)(ying)保(bao)護對象(xiang)之間必(bi)須保(bao)持短的(de)相隔長度(du)。爆(bao)破(po)(po)(po)有害效應(ying)(ying)隨(sui)距(ju)(ju)離的(de)增加有規律地衰減(jian)，用距(ju)(ju)離作為安(an)全(quan)(quan)尺度(du)可限定爆(bao)破(po)(po)(po)有害效應(ying)(ying)在允許限度(du)之內。中(zhong)國《爆(bao)破(po)(po)(po)安(an)全(quan)(quan)規程》規定了(le)爆(bao)破(po)(po)(po)地震安(an)全(quan)(quan)距(ju)(ju)離，個別(bie)飛散物安(an)全(quan)(quan)距(ju)(ju)離，以及爆(bao)炸沖擊波的(de)安(an)全(quan)(quan)距(ju)(ju)離。
