小打鹅尾矿库尾矿堆积坝稳定性研究

由于小打鹅尾矿库区地形条件限制,使得该尾矿库存在"两高一快"的特殊性.为了确保尾矿库工程安全可靠,在尾矿库初步设计完成后,采用物理模型实验、数值模拟和理论分析方法,分析和研究了尾矿堆积坝的稳定性,获得了尾矿堆积坝的结构组成、设置坝体排渗设施与不设排渗设施条件下尾矿坝渗流场的变化规律,以及不同工况下尾矿坝的稳定性等成果.这些研究成果为该尾矿库的设计和安全生产管理提供了科学依据.至今该尾矿库已安全运行五年多,一切正常.

Stability of Tailings Dam of Xiaodae Tailings Pond

Due to the limitation of the topography of Xiaodae tailings pond， the height of the starter dam is 72.5m and increases very fast (the average rate was 18.5m/a). To ensure its safety， the stability analysis was carried out through physical model tests， numerical simulation and theoretical analysis after primary design of the tailings pond. The structural composition of tailings dam， the variation rules of seepage field with or without drainage system in the dam， and the stability of tailings dam under different working conditions were obtained. Results could be helpful to the design and safety management of the tailings pond. So far， the dam has been stably utilized for over five years.
