上游式尾矿堆积坝坝面排水系统的重要性

Importance Analysis of Drainage System on Upstream Tailings Dam Surface

以上游式尾矿坝坝面排水系统为研究对象,分析了传统尾矿库坝面排水系统的布置方式。研究发现,尾矿堆积坝坝面排水系统的汇水面积随着尾矿坝的上升,可能会发生质的变化。针对此问题,结合实际项目的解决方案,提出在进行上游式尾矿库设计时应对尾矿库坝面排水系统汇水面积异常变化进行提前统筹,对已投运的尾矿库项目应及时发现、立即改造,清除安全事故隐患。

Taking the upstream tailings dam surface drainage system as the research object,the layout of the traditional tailings dam surface drainage system is analyzed.It is found that the catchment area of the drainage system on the dam surface of the tailings dam may change qualitatively with the rise of the tailings dam.In view of this problem,combined with the solution of the actual project,it is proposed that the dissimilation of the catchment area of the drainage system on the dam surface of the tailings pond should be coordinated in advance during the design of the upstream tailings pond,and the tailings pond projects that have been put into operation should be found and reconstructed in time to eliminate potential safety hazards.
