摘要: 干式尾砂堆存工艺起源于20世纪60年代的黄金提纯技术,相比其他尾砂贮存方式,干式堆存在安全、环保及基建投资等方面有其独特的优越性,但因其运行成本过高一直未广泛应用于尾矿库建设,随着压滤机技术的改进,干式尾砂堆存筑坝将成为尾矿堆存发展的新趋势。通过对某一干式堆存尾矿坝稳定性的分析,指出了在降雨条件下影响干式尾矿堆积坝稳定性的因素。

Abstract: Dry tailings stockpiling technology was originated from gold purification technology in sixties of the last century. Compared with other tailings storage methods, dry stockpiling has its own advantages on aspects like safety, environmental protection and capital investment, but it hasn't been used widely in construction of tailing pond due to its high running costs. With the improvement of press filter technology, dry tailings stockpiling damming will become the new trend for development of tailings stockpiling. Through the analysis and research of stability of a dry stockpiling tailing dam, factors, which influence the stability of dry tailings dam under condition of raining, are analyzed.
