Tailing dam construction method coupled with tailing stockpiling process
The invention discloses a tailing dam construction method coupled with a tailing stockpiling process. The tailing dam construction method comprises the following steps that S1, the earth surface of a damming area and the earth surface of a tailing pond area are cleaned, leveled and laid with an impermeable layer; s2, an initial dam is built on the impermeable layer, a blocking dam is built on the downstream, a damming area is formed in the area between the blocking dam and the initial dam, a tailing pond is formed between the initial dam and the original terrain, and a tailing clarification water area is formed at the tail of the pond area; and S3, along with rising of the beach face in the tailing pond, damming and heightening are conducted in sequence by stages through dry-discharged tailings in the damming area, damming is propelled from the initial dam to the blocking dam until the last-stage construction is completed in front of the blocking dam, and the whole tailing dam is formed. The tailing stockpiling process and the tailing dam construction method are coupled, the dry stockpiling process and the wet stockpiling process are combined, the method has the advantages of being high in tailing pond capacity utilization rate, capable of saving investment and the like, and meanwhile the practical problems that single dry stockpiling or single wet stockpiling tailing ponds are not easy to produce and operate, high in construction investment and high in operation cost are solved.
本发明公开了一种耦合尾矿堆存工艺的尾矿坝建设方法，包括以下步骤：S1、筑坝区及尾矿库区域清理地表并整平铺设防渗层；S2、在防渗层上建设初期坝，并在下游建设拦挡坝，在拦挡坝至初期坝之间区域形成筑坝区，在初期坝与原地形之间形成尾矿库，库区尾部形成尾矿澄清水域；S3、随尾矿库内滩面上升，在筑坝区内采用干排尾矿依次分期筑坝加高，筑坝由初期坝向拦挡坝方向推进，直至在拦挡坝前完成最后一期施工，形成尾矿坝整体。本发明耦合尾矿堆存工艺和尾矿坝建设方法，将干式堆存和湿式堆存工艺相结合，具有尾矿库库容利用率高、节省投资等特点，同时解决了单一干排堆存或单一湿式堆存尾矿库不易生产运营、建设投资高、运营成本高的实际问题。
