尾矿库坝体安全稳定性影响因素分析及对策措施

Analysis of influencing factors on safety and stability of tailings dam and Countermeasures

我国矿山每年产出尾矿超过3亿吨,因采矿产生废石的堆放量日益剧增,如果堆放及处置不当易发生安全事故,将会给人们生命财产与环境带来重大损失,为了保证矿山生产可持续发展,对尾矿坝体稳定性及安全管理方面的研究十分必要,本文通过参阅大量的参考文献介绍了尾矿坝体安全稳定性相关概念,总结了我国尾矿库坝体稳定性影响因素,同时计算出坝坡抗滑稳定最小安全系数,确定坝体边坡是否处于危险状态,为提高尾矿库坝体安全稳定性制定了具体措施。

The output of tailings in mines in China exceeds 300 million tons every year.Because of the increasing stacking of raw and waste stones from mining,if improper stacking and disposal are prone to safety accidents,it will bring great losses to people's lives,property and environment.In order to ensure the sustainable development of mine production,the stability of tailings dam body and safety management are concerned.It is necessary to study the safety and stability of tailings dam body.This paper introduces the related concepts of safety and stability of tailings dam body by referring to a large number of references,summarizes the influencing factors of stability of tailings dam body in China,calculates the minimum safety factor of anti-sliding stability of dam slope,determines whether the dam slope is in dangerous state,and improves the safety of tailings dam body.Specific measures have been formulated for stability.
