摘要
通过对沃溪矿区采空区及充填现状的分析 ,综合各种充填方法的特点 ,设计出一种行之有效的新的充填方法———钻孔充填法 ,解决了沃溪矿区上部空区处理不到位、安全隐患大的问题。通过对充填料坍落度、流动性、强度等指标的试验及充填效果分析 ,认为该充填新工艺可靠、实用。
Through analysis of the current filling condition of the mined-out area in the upper part of Woxi mineral field and based on the different characteristics of different filling methods,a fresh and effective filling method was designed and adopted i.e.supplying filling materials through drill-hole,which kept the mined-out area from hidden trouble against safety.From experiments of intensity,fluidity,collapsibility of the filling materials,it showed that the new filling method was reliable.
