某钽铌矿尾矿库闭库整治工程设计研究

Design and Research on Tailing Pond Closure in a Certain Ta/Nb Mine

某钽铌矿尾矿库即将库满停用,进入闭库程序。整治设计采取了沿坝轴线射水造混凝土防渗墙、翻修排水棱体和加设溢洪道消力池及钢筋混凝土护面等整治措施。经渗流及坝坡稳定等分析计算,表明设计采取的整治加固措施具有较好的效果,满足尾矿库安全要求。

The tailing pond of a certain Ta/Nb mine is full and going to be closed. To prevent environment pollution, the control measures of building concrete impervious wall along dam axial line, reconstructing drainage mound and adding spillway basin as well as paving with reinforced concrete are taken in design. It is indicated by calculation of seepage flow and analysis of slope stability that the tailing pond can meet the environmental protection requirement after the control and reinforcing measures are taken in design.
