Vertical and horizontal combined tailing pond stabilizing structure and construction method
The invention belongs to the technical field of mining and mine environment protection, and particularly relates to a vertical and horizontal combined stable structure and a construction method. The stable structure comprises a vertical anti-seepage body, a horizontal self-cementing layer and a flow guide and seepage drainage layer. The vertical anti-seepage body is located below the foundation on the inner side of the tailing pond dam body, and the horizontal self-cementing layer and the flow guiding and seepage draining layer are sequentially constructed on the foundation on one side of the vertical anti-seepage body from bottom to top. Materials of the vertical impermeable layer comprise a self-cementing material, a retarding and water reducing agent and the like, and an upper-wall lower-curtain impermeable mode is adopted. Materials of the horizontal self-cementation layer mainly comprise self-cementation materials, retarding and water reducing agents, fibers and the like, and the horizontal self-cementation layer is laid on the side close to the dam body within a certain range. And the lower part of the water collection and drainage blind ditch is filled with large-particle-size river sand, and the upper part of the water collection and drainage blind ditch is filled with medium-particle-size river sand. The vertical and horizontal combined stable structure is adopted, and the effects of seepage prevention, stability, remarkable economic benefits and the like are achieved.
本发明属于矿山开采、矿山环境保护技术领域，具体涉及一种垂直与水平结合的稳定结构及施工方法。稳定结构包括垂直防渗体、水平自胶结层和导流排渗层；垂直防渗体位于尾矿库坝体内侧的地基以下，水平自胶结层和导流排渗层自下而上依次构建在垂直防渗体一侧的地基上。本发明的垂直防渗层材料包括自胶结材料、缓凝减水剂等，采用上墙下幕的防渗方式。水平自胶结层材料主要包括自胶结材料、缓凝减水剂、纤维等，在靠近坝体一侧进行一定范围内铺设。导流排渗层中设置集水导排盲沟，集水导排盲沟下部填充大粒径河砂，上部填充中粒径河砂。本发明采用垂直与水平相结合的稳定结构，达到了防渗、稳定、经济效益显著等效果。
