在工程爆破中，礦用型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，鄭州礦用型聚能管基本(ben)連接方式有：串(chuan)聯、并(bing)聯、串(chuan)并(bing)聯和并(bing)串(chuan)聯等。電(dian)(dian)(dian)(dian)力(li)(li)起(qi)爆(bao)(bao)法具有較(jiao)安全、可(ke)靠、準確(que)、高效(xiao)等優點，在國內外(wai)仍占有較(jiao)大比重。在大、中型(xing)爆(bao)(bao)破中，主要仍是用(yong)電(dian)(dian)(dian)(dian)力(li)(li)起(qi)爆(bao)(bao)。特別是在有瓦斯、礦塵爆(bao)(bao)炸的(de)環境中，電(dian)(dian)(dian)(dian)力(li)(li)起(qi)爆(bao)(bao)是主要的(de)起(qi)爆(bao)(bao)方法。但電(dian)(dian)(dian)(dian)力(li)(li)起(qi)爆(bao)(bao)容易受各(ge)種電(dian)(dian)(dian)(dian)信(xin)號的(de)干擾(rao)而發生早爆(bao)(bao)，因此在有雜散電(dian)(dian)(dian)(dian)、靜電(dian)(dian)(dian)(dian)、雷電(dian)(dian)(dian)(dian)、射頻電(dian)(dian)(dian)(dian)、高壓感應電(dian)(dian)(dian)(dian)的(de)環境中，不能使用(yong)普通電(dian)(dian)(dian)(dian)雷管。
