Near-city abandoned strip mine stratum reconstruction method
The invention discloses a near-city abandoned strip mine stratum reconstruction method. The near-city abandoned strip mine stratum reconstruction method comprises the following steps that in a strip mine pit, a space of which the horizontal elevation is lower than the elevation of a city drainage system is divided into a water storage area, a strip mine side slope, close to one side of a city, of the water storage area is taken as a working wall, other strip mine side slopes are taken as non-working walls; A city drainage system communicates with the water storage area; the water storage area is filled with a water storage medium, and an inverted-pyramid-frustum-shaped temporary water storage pond is reserved on one side, close to the working wall, of the water storage area; a water storage isolation layer is laid on one side face, close to the working wall, in the temporary water storage pond, and filtering layers are laid on the other side faces and the bottom face of the temporary water storage pond; a flexible isolation layer is laid in a non-water-storage-pond area in the water storage area; a backfilling layer, a waterproof layer and a reclamation layer are sequentially laid on the flexible isolation layer from bottom to top; and a water taking well is arranged in the center of the water storage area. According to the near-city abandoned strip mine stratum reconstruction method, the city water storage space is constructed by utilizing the strip mine pit to relieve the waterlogging problem in a rainy period, the space is abundant, the capacity is large, and the cost is low; and the pit part of a strip mine is partially backfilled to relieve the potential safety hazard of the slope.
本发明公开了一种近城市废弃露天矿地层重构方法，在露天矿坑中，将水平标高低于城市排水系统标高的空间划分为储水区，储水区靠近城市一侧的露天矿边坡为工作帮，其余露天矿边坡为非工作帮；将城市排水系统与储水区连通；在储水区内充填储水介质，在储水区靠近工作帮一侧预留倒棱台状临时储水池；在临时储水池内靠近工作帮的一侧面铺设储水隔离层，在临时储水池的其他侧面和底面铺设过滤层；在储水区内非储水池的区域铺设柔性隔离层；在柔性隔离层上由下至上依次铺设回填层、阻水层和复垦层；在储水区中心位置布置取水井。本发明利用露天矿坑构建城市储水空间缓解雨期的内涝问题，空间充裕、容量大、成本低；露天矿矿坑部分回填，缓解边坡安全隐患。
