摘　　要：撞楔法是一种平巷掘进时穿过松软岩体的方法。三道岔矿在残矿回采作业中,经过反复的试验之后,采用撞楔法支护进路式回采、嗣后充填的方式对留矿采矿法存窿矿石进行回收,取得了较好的经济和社会效益。Wedge-impacting method is a way to pass soft rock in drift excavation process. When the remnant ore of shrinkage stoping method is recovered in Sandaocha gold mine, wedge-impacting route support and backfilling method is successfully used.
