尾矿库安全评价存在的问题与对策

Problems and countermeasures of safety evaluation of tailing pond

指出了目前尾矿库安全评价中在尾矿料物理力学性质试验、沉积尾矿料物理力学性质概化分区方法、尾矿料本构模型与固结理论、尾矿库防渗与排渗系统服役性能长期演化规律、尾矿库溃坝致灾过程研究等方面存在的问题,分析了产生上述问题的原因,提出了今后应重点研究的方向。

The existing problems in the safety evaluation of tailing pond are pointed out, including the physical and mechanical tests on tailing materials, the generalized partitioning methods for physical and mechanical properties of deposited tailing materials, the constitutive models and the consolidation theories, the long-term performance evolution of drainage systems as well as the researches on the breaching process of tailing pond due to different disaster-induced factors. In this research, the reasons for the above problems are analyzed. Meanwhile, the key research direction of the safety evaluation of tailing pond in future is proposed as well.
