Tailing pond dam body, tailing pond and stacking method of tailing pond dam body
The invention discloses a tailing pond dam body, a tailing pond and a heaping method of the tailing pond dam body, relates to the technical field of tailing ponds, and solves the problems that in the prior art, the tailing pond dam body is heaped by adopting coarse-fraction settled sand, sulfide in the coarse-fraction settled sand is oxidized, acid wastewater is generated, and the stability of the tailing dam is affected. The tailing pond dam body comprises a first dam body section, a second dam body section and a third dam body section, the first dam body section is located at the bottom end of one side of the second dam body section, the third dam body section is located at the top end of the other side of the second dam body section, the first dam body section is a concrete rockfill dam, and the third dam body section is a high-strength rockfill dam formed by fine silt tailings and cementing materials. According to the tailing pond dam body, on one hand, the stability of the tailing pond dam body can be enhanced through the action of the multiple dam body sections, on the other hand, the third dam body section is a high-strength rock dam formed by fine silt tailings and cementing materials, local materials can be used, the damming cost is reduced, and the stability and the environmental protection property of the dam body are enhanced.
本发明公开了一种尾矿库坝体、尾矿库以及尾矿库坝体的堆筑方法，涉及尾矿库技术领域，解决了现有技术中采用粗粒级沉砂堆筑尾矿库坝体，粗粒级沉砂中的硫化物被氧化，产生酸性废水以及影响尾矿坝稳定性的问题。本发明的尾矿库坝体，包括第一坝体段、第二坝体段和第三坝体段，第一坝体段位于第二坝体段一侧的底端，第三坝体段位于第二坝体段另一侧的顶端，并且第一坝体段为混凝土石坝，第三坝体段为细泥尾矿与胶结材料形成的高强度体石坝。一方面，本发明的尾矿库坝体通过多段坝体段的作用，可增强尾矿库坝体的稳定性，另一方面，第三坝体段为细泥尾矿与胶结材料形成的高强度体石坝，可就地取材，降低筑坝成本，增强坝体的稳定性和环保性。
