炸礁用炸药爆破水下岩石，常用于浚深、拓宽航道和港池，清除碍航礁石，开挖码头、船闸、船坞等水工建筑物的基坑。爆破方法有水下裸露爆破、钻孔爆破和硐室爆破三种。水下炸礁，对附近地面和水体会产生较强的震动效应和水冲击波，应对附近保护对象进行监测，划定危险区域，严格控制一次起爆炸药量。必要时对重要建筑物采取气泡帷幕等防护措施。水下裸露爆破 在加工好的炸药包旁边加捆坠石或砂袋，将几个或几十个药包连在一起，构成网状，沉放到水中礁石的表面，在水压力的作用下，不加覆盖进行爆破。这种爆破方法操作简便，机动灵活，但爆炸能量利用率低,炸药消耗量大，多在礁石不厚、零星分散,或流速大、水流紊乱、钻孔困难的条件下采用。中国可在流速5.5米/秒，水深10～15米的条件下进行水下裸露爆破。水下钻孔爆破 利用炸礁船（又称钻孔爆破船）进行水下钻探爆破。炸礁船有普通式和自升式两种。自升式炸礁船的四角有液压支柱，工作时将支柱下至水底后把船顶升出水面一定高度,以避开急流和波浪的影响,保持船舶的稳定。炸礁船上有钻机和轨道，钻机在轨道上移动以对准钻孔位置。钻孔方法视河床底质而定，在有覆盖层或为破碎的礁石时,一般采用双套管钻进方法,即先下外套管至覆盖层顶以保护钻孔，再把带钻头的内套管钻至覆盖层底，然后用钻具钻孔至要求深度。钻完一孔后立即将钻孔冲洗干净并用堵眼管塞住，防止泥砂进入孔内。全部的孔钻完后,先拔起堵眼管，冲洗钻孔,再把在船上预制好的炸药筒逐个送入孔内，钻孔顶部留40～60厘米用砂堵塞,然后拔起内、外套管,从套管底端取出导线,把各孔导线联成爆破网路并与主导线连接,船舶撤离危险区后通电起爆。这种爆破方法适用范围广，爆破效果较好，但受水深和流速的限制。中国已可在流速4.5米/秒、水深15米的条件下进行水下钻孔爆破。水下硐室爆破 一般是利用岸边有利地形或在江中露出的孤礁上做挡水围堰，抽水后开挖导硐，挖到爆破位置后开挖药室，把经过防水加工的药包和起爆体装入药室，外用泥砂堵塞，通电起爆。这种爆破方法一次可破碎大量礁石，并能抛掷至较远处，清碴量少，适用于开挖石方量集中、旁边有深槽可容纳抛出石碴的水域。近年来遥控爆破技术试验成功，起爆不用导线，从根本上消除了爆破网路出现故障的可能性，提高了起爆的可靠性，并有可能在特殊情况下进行控制爆破。
