摘要:
地下采空区是地下矿山开采活动遗留下来的一种地质产物,是矿山地质灾害最主要诱发因素之一。地下采空区对矿山的正常生产和周边人民群众的生命安全、生产生活都造成了严重的影响。排山楼金矿经过二十余年的高强度开采,其地下采空区总面积达45470 m2,最大空场高度达68 m,存在着极大的安全隐患。作者结合工程实际,通过对排山楼金矿的采空区地质特点进行分析,提出了VCR辅助下的逐步充填的技术方案,消除了采空区对安全生产的严重威胁,同时对我国采空区的治理工作具有一定的参考价值。
Abstract:
The underground gob is a kind of geological legacy of mining activity and one of the most important factors of mine geological disasters. At same time ,the gob caused a serious impact to liv-ing and production activities around it. After twenty years high -intensity exploitation, the total empty area of Paishanlou gold mine is up to 45 470 m2 , of which the highest up to 68 m. Based on the analysis of geological characteristics of the gob, the author put forward the VCR-assisted grad-ual-filling technical scheme, which can eliminate the serious threat to safety production.
