摘要
为保证贵州簸箕田金矿复杂矿床安全、高效开采,利用FLAC^(3D)数值模拟软件分别对3种采矿法(上向进路充填采矿法、上向水平分层充填采矿法、下向分层充填采矿法)不同采场结构参数进行了数字模拟分析。结果表明,采场高度3 m、宽度6 m的上向进路充填采矿法最优,更符合矿山开采安全、稳定、经济要求。研究成果对类似复杂矿山开采具有指导意义。
In order to ensure safe and efficient mining of Zhenfeng Bojitian complex gold ore deposit,simulation analyses were performed by using FLAC^(3D) numerical simulation software for three mining methods respectively,including overhand drift cut⁃and⁃fill mining method,overhand cut⁃and⁃fill mining in horizontal slice,and underhand sliced cut⁃and⁃fill method,with different stope structure parameters.The results show that the overhand drift cut⁃and⁃fill mining with the stope height of 3 m and width of 6 m is the best method,which can meet the safe,stable and economical requirements in the mine.This research has guiding significance for similar complex mines.
