钻炸法 Drilling and blasting

(重定向自Rock blasting)

钻炸法,又称钻爆法,为使用爆破方式进行隧道开挖作业,同字面上意思,是在开挖处先钻出一个洞,把炸药埋入其中,然后引爆的做法。由于炸药位于洞中,力量不易散失,所以能够发挥炸药完全的力道,炸碎大量的岩石,使工程快速进行,施工进度较容易掌握,故为大多数岩石隧道施工及采矿所采用。施工方流程包含:

这一方法从早期由人工手把钎、锤击凿孔,用火雷管逐个引爆单个药包,发展到用凿岩台车或多臂钻车钻孔,应用毫秒爆破、预裂爆破及光面爆破等爆破技术。施工前,要根据地质条件、断面大小、支护方式、工期要求以及施工设备、技术等条件,选定掘进方式。
