Upstream type high-strength reinforced wide-top damming method and structure for fine-particle tailings
The invention relates to the technical field of tailing damming, and particularly relates to an upstream type high-strength reinforced wide-top damming method and structure for fine-particle tailings.According to the upstream type high-strength reinforced wide-top damming method and structure for the fine-particle tailings, strength reinforcement is conducted on the beach face of a current accumulation dam through riprap and silt squeezing, and the foundation strength of damming is guaranteed; tailing grading is conducted through a cyclone, direct damming is conducted through the underflow tailings of the cyclone, and high-strength geosynthetics are laid in the damming tailings at intervals; and the strength of a dam body is improved through the friction and clamping effects between the geosynthetics and the damming tailings, the standard penetration index of the tailings on the surface layer is greatly increased, the physical and mechanical properties of the tailings in the dam bodyare improved, and the stability and safety coefficient of the dam body is increased. By implementing the method, the stability of the tailing dam body under various operating conditions can be guaranteed, the construction difficulty is lowered, and investment is reduced.
本发明涉及尾矿筑坝的技术领域，特别是涉及一种细颗粒尾砂上游式高强度加筋宽顶筑坝方法及结构，其通过抛石挤淤对现状堆积坝滩面进行强度加固，保证筑坝的基础强度，通过旋流器进行尾砂分级，采用旋流器底流尾砂直接筑坝，筑坝尾砂中间隔铺设高强度土工合成材料，通过土工合成材料与筑坝尾砂间的摩擦、钳固作用提高坝体强度，大大提高表层尾砂标贯指数，提高坝体内尾砂物理力学性质，提高坝体稳定安全系数，该种方法的实施既能保证尾矿坝在各种运行工况下的坝体稳定，又降低了施工难度，减少了投资。
