某钒铁矿分区协同开采方案优化

摘要

针对某钒铁矿资源开采规划不明确,钒铁矿开采相互制约,矿量积压严重,采空区影响矿山安全生产的问题,提出了钒铁矿分区协同开采优化方案。方案将勘探线7#~10#线划为东区,10#~15#线划为中区,15#~21#线划为西区,采用不同的采矿方法进行分区设计与分区回采。新方案设计开采资源储量相比原方案增加了1064．7万t,提高设计采出矿量约20%；东区增加了矿石回收率9个百分点,中区增加了21个百分点,西区增加了14个百分点,使矿产资源得到了充分有效回收,经济效益得到了显著提高；同时,消除了采空区危害,改善了铁矿上盘钒矿的开采安全条件,有效保障了安全生产条件。成果对于类似矿山具有重要借鉴意义。%Due to the problems of a vanadium and iron mine such as unclear resource mining plan,mutual restriction of mining,serious ore backlog and goaf affecting mine safety production, the collaborative optimization mining scheme is pro-posed. The mining area is divided in to eastern area (7# ~10# prospecting line),central area (10# ~15# prospecting line) and western area (15# ~21# prospecting line ),different mining methods are used for partitioning design and partitioning mining. Compared to the original mining scheme,the reserves is increased by 10. 674 million t and amount of ores is improved 20%, the ore recovery of the eastern area is increased by 9%,the ore recovery of the central area is increased by 21%,the ore recov-ery of the western area is increased by 14%,the mineral resources of the mine is used fully,the economic efficiency is im-proved significantly. Besides that,the goaf hazard is eliminated,the mining safety condition of the vanadium ore upper the iron ore are improved,the safety production conditions of the vanadium and iron mine is guaranteed,the the collaborative optimiza-tion mining scheme proposed in the paper can provide reference for the similar mine.
