Tailing pond risk hidden danger treatment method
The invention provides a tailing pond risk hidden danger treatment method which comprises the following steps: in the stage of finishing initial dam reinforcement and slope cutting of a fill dam, building a dam crest flood control wide platform by utilizing the slope cutting volume of the fill dam, setting a slope ratio from bottom to top on the top surface of the platform, designing the slope ratio to be 0.5%, and guiding rainfall on the top surface of the platform to the upstream surface of the platform, and the dam face is prevented from being scoured due to over-steep gradient. The flood discharge mode that the flood control wide platform is matched with the flood discharge box culvert-open channel is adopted, the overall stability of the tailing dam can be improved, meanwhile, the problem that the dry beach length and the safety superelevation are insufficient due to the fact that the reservoir area beach length is too short is effectively solved, the overall safety of the tailing dam is effectively improved, the flood control requirement is met, and the purpose that no water is stored in the reservoir area after the reservoir is closed is achieved; and long-term treatment and long-term safety of a project after reservoir closing are realized.
本发明提供了一种尾矿库风险隐患治理方法，在完成初期坝加固，在堆积坝的削坡阶段，利用堆积坝的削坡方量修建坝顶防洪宽平台，平台顶面设置自下而上的坡比，可设计为0.5%，将平台顶面降雨引至平台上游面，避免因坡度过陡对坝面形成冲刷。本发明采用防洪宽平台配合排洪箱涵—明渠的泄洪方式，不仅能够提升尾矿坝整体稳定性，同时有效的解决库区滩长过短导致的干滩长度和安全超高不足的问题，有效的提升尾矿坝整体安全，满足防洪要求，达到闭库后库区不存水的目的，实现闭库后工程的长治久安。
