在工程爆破中，礦用型雙向聚能管公司常用的起爆方法有：電力起爆法、導火索起爆法、導爆索起爆法、導爆管起爆法。電力起爆法是利用電能使雷管爆炸，進而起爆炸藥的起爆芳法。它所需的器材有：電雷管、導線和起爆電源。電爆網路的連接形式，要根據爆破方法、爆破規模、工程的重要性、所選起爆電源及其起爆能力等進行選擇，南京礦用型雙向聚能管基本連接方式有(you)：串聯(lian)(lian)、并(bing)聯(lian)(lian)、串并(bing)聯(lian)(lian)和(he)并(bing)串聯(lian)(lian)等(deng)。電(dian)(dian)(dian)(dian)(dian)力(li)(li)(li)起(qi)(qi)爆(bao)法具有(you)較(jiao)安全(quan)、可靠、準確、高(gao)效等(deng)優點(dian)，在國內外仍占有(you)較(jiao)大比重。在大、中(zhong)型爆(bao)破(po)中(zhong)，主(zhu)要仍是(shi)用電(dian)(dian)(dian)(dian)(dian)力(li)(li)(li)起(qi)(qi)爆(bao)。特別是(shi)在有(you)瓦斯(si)、礦塵(chen)爆(bao)炸的(de)環境中(zhong)，電(dian)(dian)(dian)(dian)(dian)力(li)(li)(li)起(qi)(qi)爆(bao)是(shi)主(zhu)要的(de)起(qi)(qi)爆(bao)方法。但電(dian)(dian)(dian)(dian)(dian)力(li)(li)(li)起(qi)(qi)爆(bao)容易受(shou)各種(zhong)電(dian)(dian)(dian)(dian)(dian)信號的(de)干擾而發生早(zao)爆(bao)，因此在有(you)雜散電(dian)(dian)(dian)(dian)(dian)、靜電(dian)(dian)(dian)(dian)(dian)、雷(lei)電(dian)(dian)(dian)(dian)(dian)、射(she)頻電(dian)(dian)(dian)(dian)(dian)、高(gao)壓(ya)感應電(dian)(dian)(dian)(dian)(dian)的(de)環境中(zhong)，不能使用普通電(dian)(dian)(dian)(dian)(dian)雷(lei)管。
