New method for constructing combined drainage and seepage system of valley-type tailings pond
The invention discloses a novel construction method for a combined seepage drainage system of a valley-type tailing pond, and the seepage drainage system is formed by combining a seepage drainage prism, a horizontal seepage drainage structure and a vertical seepage drainage structure (13). The drainage and seepage prism (4) is formed by combining a cement blanket (5), a rockfill body (9), geotechnical cloth (8), a broken stone hardcore (11), a coarse tailing protection layer, geotechnical cloth (8), a coarse tailing protection layer and a dry rubble protection layer (12) on the outermost layer, the horizontal drainage and seepage structure is formed by connecting water collecting pipes (7) and drainage pipes (6), the water collecting pipes (7) are laid in rows along the current dry beach face, and the drainage pipes (6) are laid in rows along the current dry beach face. The drainage pipe (6) is lapped with the water collecting pipe (7); and the vertical drainage structure (13) is arranged on the later-stage drainage dry beach face and penetrates through a tailing sand layer to be connected with the water collecting pipe (7). The method has the advantages of being convenient to construct, economical, effective, high in applicability, good in seepage drainage effect, small in occupied area and free of resource consumption, and the problem that catchment of the valley type tailing pond is difficult to drain in time is effectively solved.
本发明公开了一种山谷型尾矿库组合排渗系统构建新方法，排渗系统由排渗棱体、水平排渗结构、垂直排渗结构(13)组合构成，排渗棱体(4)由靠近山体一侧向外依次设有水泥毯(5)、堆石体(9)、土工布(8)、碎石垫层(11)、粗尾砂保护层、土工布(8)、粗尾砂保护层及最外层的干砌块石保护层(12)组合构成，水平排渗结构由集水管(7)和排水管(6)连接构成，集水管(7)沿现状干滩面成排铺设，排水管(6)与集水管(7)搭接；垂直排渗结构(13)布置在后期排放干滩面上，并贯通尾砂层与集水管(7)衔接。本发明具有施工便捷、经济有效、适用性强、排渗效果好，且不占地、不耗费资源的特点，有效解决了山谷型尾矿库汇水难以及时排出的难题。
