  • 尾矿坝溃坝原因及安全稳定性分析……周杰,曾晟*,孙冰
  • 摘 要:尾矿库是矿山安全生产的的重要设施,同时也是重大危险源。尾矿坝溃坝必对下游人民的生命与财产造成巨大危害,对环境造成严重污染,研究尾矿坝溃坝原因显得尤为重要。总结了导致尾矿坝溃坝的3种主要因素,即渗透、洪水及地震,分析了尾砂物理性质、坝坡、坝高、子坝堆积高度、洪水和地震作用等对尾矿坝稳定性和失稳概率的影响,提出了提高坝体稳定性、建立安全监测系统、完善安全管理体系等有利于尾矿坝安全的措施,为尾矿坝安全管理提供依据。

    Analysis on thecauses of dam failure and the safety and stability of tailings dam……Zhou Jie,ZengSheng,Sun Bing

    AbstractTailings pond isan important facility for mine safe production,and also a major hazardsource.Tailings dam failure will pose a great threat to peoples lives and property downstream,and cause serious pollution to theenvironment,making it very important to study the cause of dam failure.3factors that cause tailings dam failure are summarized,being the permeation,theflood and the seismic action.The influence of tailings physical property,damslope,dam height,stacking dam height,flood and seismic action on the damstability and destabilization probability are analyzed.Measures that arehelpful to improve tailings dam safety like improving the stability of dambody,establishing safety monitoring system and enhancing safety managementsystem are put forward,providing basis for safety management of tailings dam.
