Tailing pond pollution control flow guide and seepage prevention method
The invention discloses a tailing pond pollution control flow guide anti-seepage method which comprises the following steps: firstly, determining a tailing pond bottom bedrock breaking development area and a damaged area of a natural or artificial material anti-seepage layer, and carrying out grouting anti-seepage reinforcement treatment on the damaged area; calculating a precipitation radius and a dominant channel according to the permeability coefficient of each stratum in the tailing pond area, and arranging a peripheral vertical diversion well array on the periphery of the tailing pond; and transverse flow guide holes are formed in the sealed slag heap for drainage, so that the water content of the slag heap in the warehouse can be reduced, and the oxidation, dissolution, release and diffusion migration rates of pollutants are reduced. The method is suitable for the tailing pond with the pollutant migration and diffusion problem, grouting seepage prevention is conducted after a damaged area is found out, then the vertical diversion well array around the tailing pond is constructed to conduct diversion on peripheral underground water, the underground water penetrates through the water-resisting layer to be directly drained to a deep underground water channel, and meanwhile the ground surface drainage prevention measure and the bottom seepage prevention measure of the tailing pond are combined. External shallow underground water can be effectively isolated, and interaction between peripheral underground water and the interior of the tailing pond is greatly reduced.
本发明公开了一种尾矿库污染控制导流防渗的方法，步骤为：先确定尾矿库库底基岩破碎发育区、天然或人工材料防渗层的破损区，对破损区进行注浆防渗加固处理；根据尾矿库区各地层渗透系数计算出降水半径和优势通道，在尾矿库外围布置周边垂直导流井阵；再对封库的渣堆内部，设置横向导流孔引流，可降低库内渣堆含水量、减少污染物氧化溶解释放与扩散迁移速率。本发明适用于发生污染物迁移扩散问题的尾矿库，查明破损区后进行注浆防渗，再构建尾矿库周边垂直导流井阵对外围地下水进行导流，穿过隔水层直接引流至深层地下水通道，同时结合尾矿库地表防排措施和底部防渗措施，可有效隔绝外部浅层地下水，大幅减少外围地下水与尾矿库内部的交互作用。
