摘要
尾矿库的安全稳定在矿山的安全生产和环境保护中具有十分重要的意义。尾矿库安全评价应该研究坝及其附属构筑物的安全状况,评价尾矿库的安全等级。本文立足于尾矿库工程的实践经验,探讨了尾矿库安全评价中应该涉及的科学问题,并对其相应的评价方法进行了探讨,指出了尾矿库安全评价应该采用的基于有限元理论的定量评价方法。本文认为排水不良和地震液化是影响尾矿坝稳定性的重要因素,应该在评价过程中给予重点的关注和研究。此外,在尾矿库的安全评价中,应更多地采用有限元数值计算方法研究上述科学问题。
The safety and stability of the tailing reservoir plays an important role in the mining production and environmental protection. Safety assessment on tailing reservoir should be based on safety conditions of dam and its affiliated construction and the assessment on safety state of the tailing reservoir. Based on practice of the projects of tailing reservoir, scientific issues and corresponding evaluation methods are discussed and analyzed in this paper, and thus FEM quantitative evaluation methods are discovered proper in safety assessment of tailing reservoir. The impeded drainage and liquefaction are the two key factors in dam stability, which should be given more attention and research in safety assessment. What＇ s more, numerical simulation methods of FEM should be used to study the scientific issues of safety assessment on tailing reservoir.
