Seepage draining method for fine-grained tailing pond, seepage draining system and application
The invention provides a seepage draining method for a fine-grained tailing pond, a seepage draining system and application, and relates to the technical field of tailing treatment. According to the seepage draining method, a seepage draining area is defined on the beach surface of the tailing pond through adopting a floating body, a base layer and a sand wall are formed in the seepage draining area through using deposition and solidification of coarse tailings, a seepage draining body is arranged in the sand wall, and the permeability coefficient of the coarse tailings is higher than the permeability coefficient of fine tailings, so that moisture in the coarse tailings enters a water guide pipe along the seepage draining body firstly and then flows to a sub-dam drainage ditch to be drained; and a large amount of moisture is contained in the fine tailings outside the seepage draining area, the moisture in the fine tailings is gradually gathered in the seepage draining area and enters the seepage draining body along with the difference of pore water pressure inside and outside the seepage draining area, the coarse tailing sand wall is used for reversely filtering the fine tailings,and the seepage draining body is used for reversely filtering the coarse tailings, so that the seepage draining body is not easy to block by the fine tailings, seepage draining of the fine tailings isrealized, the seepage draining area and the seepage slope of a dam body are increased, and the seepage draining efficiency is improved.
本发明提供了一种细粒尾矿库的排渗方法、排渗系统及应用，涉及尾矿处理技术领域。该排渗方法采用浮体在尾矿库滩面上围设一排渗区域，在排渗区域内利用粗粒尾矿沉积固结形成基层及砂墙并在砂墙内设置排渗体，由于粗粒尾矿的渗透系数较细尾矿的渗透系数要高，故粗粒尾矿中的水分会先沿排渗体进入到导水管再流至子坝排水沟排出，而排渗区域外的细粒尾矿中含有大量的水分，随着排渗区域内外孔隙水压力的差异，细粒尾矿中的水分逐渐聚集于排渗区域内并进入排渗体，利用粗粒尾矿砂墙反滤细粒尾矿，排渗体反滤粗粒尾矿，从而使得排渗体不易被细粒尾矿堵塞，实现了细粒尾矿的排渗，增加了坝体排渗面积与渗透坡降，提高了排渗效率。
