摘要
矿山经过开采后会遗留大量的采空区,通过空场法回采的矿山产生的采空区更大,会给矿山安全生产带来巨大隐患。对祁雨沟金矿井下采空区现状分析,提出了具体的采空区隐患治理方案,采用分级尾砂、废石和胶结充填技术对采空区进行治理工作,有效的防范了采空区事故。
A large number of mined-out areas will be left after mining,and the mined-out areas produced by open stoping method are even larger,which will bring great hidden dangers to mine production safety.Based on the analysis of present situation of underground mined-out area in Qiyugou Gold Mine,this paper puts forward the specific treatment scheme for hidden danger of mined-out area,which mainly adopts graded tailings,waste rock and cemented filling technology to control mined-out area,and effectively preventing mined-out area accidents.
