With high water quick setting filling material as the comment, rock or waste rock as the aggregate, through the laboratory experiments and insitu filling experiments.
通过以高水速凝充填材料作为胶结剂、以块石(或废石)作为骨料的室内模拟试验和现场充填试验,利用高水速凝材料具有早强、速凝、采场充填不需脱水的优点,加快采充作业循环,减少采空区的暴露时间,增加保安矿柱采场附近井筒周边岩石的稳定性等特点,本文结合招金股份公司三矿区3号井的特殊开采条件,采用了高水速凝废石浇注充填法,为保安矿柱的安全回收创造有利条件。
