1、前言***********#####尾矿库设计总坝高103m,总库容3296万m3,目前尾矿总堆积高度约70m。根据国家经贸委第20号令《尾矿库安全管理规定》中第十五条规定:“尾矿库使用到设计最终坝高的1/2~2/3高度时应对尾矿堆积坝进行工程地质勘察和稳定性分析”,广西***********有限责任公司委托中国有色金属工业尾矿坝监测中心对#####尾矿库进行安全评价。其主要任务为:1.对#####尾矿库现状的坝体稳定性和防洪能力及排洪系统可靠性进行验算和评价;同时还对该尾矿库堆积至最终设计标高时的安全性进行评估
2、。2.提出确保尾矿库安全运行的建议。在该项目进行过程中,得到***********及####选厂、工程勘查设计院、研究总院的大力支持和帮助,在此一并表示感谢!shouldbetightened,noloose,TerminalBoardwiringshouldbeoneoneachside,nomorethantwo.J,shieldedwire,sparewirebindingorder,reliablegrounding.7.7qualitystandard7.7.lcablesthroughthecable
