袁家村铁矿湿陷性黄土地基建尾矿坝的研究与应用

Study and Application of Setting Up Tailings Dam on Collapsible Losses Foundation in Yuanjiacun Iron Ore Mine

我国湿陷性黄土分布广阔,在湿陷性黄土地区建设尾矿库应考虑湿陷性黄土地基对坝体的影响,通过局部挖除、堆载预压、反压坡脚、滤水疏干等一系列工程措施,保证坝体的安全稳定。

Distribution and characteristics of collapsible losses in China is introduced. With Yuanjiacun iron ore project as an example, influence of collapsible losses foundation on tailings dam is analyzed. Through measures such as local excavation of collapsible losses, preloading, back pressing of slope toe, water filtration and drainage, safety of dam body is ensured and stability analysis is also done for the tailings dam.
