哈图金矿的充填技术

Research on Filling Techniques in Hatu Gold Mine

为解决哈图金矿深部开采地压控制及老空区围岩逐渐闭合破断的问题,通过基础试验与充填系统设计及技术研究,在日常采空区充填的过程中也对以往空区进行充填,解决了充填相关问题,通过一段时间的充填生产,部分破坏严重的采空区陆续充填后,地压得到明显控制,老空区围岩的弱化得以消除,保障了生产安全。

To solve the problems of ground press control in deep mining and gradual shutting and breakage of the surrounding rock in old goaf,basic tests were carried out,the filling system was designed and the filling techniques were studied in Hatu gold mine.In ordinary filling process,the old goafs were filled simultaneously,which solved related filling problems.After mining with backfill in a period of time,some old goafs with serious damage were handled,the ground press was controlled obviously,and the weakening of surrounding rocks was eliminated,which guaranteed the mining safety.
