q iankong zuanli潜孔钻机(underwater drill)一种钻岩石炮孔的施工机械。用压缩空气和液压为主动夕辅以电动。由于它的冲击器紧随钻具一起进入孔底行冲击钻孔，故名潜孔钻机。利用压缩空气和液压一动能，经过机体转换成机械冲击和回转熊，通过钻对岩石进行冲击破碎，并将岩粉排出形成炮孔。按用条件分为:①井下式潜孔钻机，由冲击器，柱架回转推进机构组成。不能自行移动，用在井下作山②露天式潜孔钻机，由冲击回转、推进提升、行走、{尘等机构组成。能自行移动，具有凿岩效率高、噪低的特点，在水利工程施工中广泛被采用。常用的号有YQ一巧O型，可钻直径150毫米、深17米的炮引也能钻凿一定角度的倾斜孔。尚有可钻直径80、10(200及250毫米以上的潜孔钻机。(吴树德)
