摘要
根据伊敏露天矿开采现状,对内排空间不足的原因进行了分析;针对内排土场空间紧张的问题,从设计角度出发,结合露天矿地质条件,讨论了在露天矿采掘、运输、排土3个环节进行技术优化。通过采掘工作线的调整,降低了排土空间的需求,采用减少剥离强度、降低运输系统占用及内排土场扩容等多重措施,保证露天矿正常生产接续。
According to the mining status of Yimin Open-pit Mine,the article analyzes the cause of insufficient internal dumping space.For the problem of internal dump space tension,from the design perspective,combined with the open-pit mine geological conditions,the article discusses the mining,transportation,drainage three links technical optimization.Through mining line adjustment,we reduce the drainage space demand,reduce the stripping strength,reduce the transportation system occupancy and internal dump expansion of multiple measures,to ensure the normal production of open-pit mine.
