摘要
针对瓮福磷矿大塘矿段采用大直径深孔阶段空场嗣后充填采矿方法,利用Mathews稳定图法及FLAC3D数值模拟的方法,分析了不同矿块结构参数采矿方案的安全性,确定经济合理的矿块结构参数,保障大塘矿作业安全和提高采矿效率,促进企业经济效益和社会效益,建设和发展绿色矿山。
In view of large diameter long-hole open stoping backfill method of Datang ore of Wengfu phosphate ore,Mathews stability diagram and FLAC3 Dnumerical simulation methods were used to analysisthe safety of the different structural parameters of ore block mining plan.Theeconomic and reasonable structural parameters of ore block was determined to protect safety,improve the efficiency of mining,promote the enterprise economic benefit and social benefit,and construction and development green mine.
