Abstract

Significant factors believed to be responsible for tailings dam failure which can lead to loss of lives, destruction of properties and assets or damage to the environment are the mechanics of material characteristics and static liquefaction. It is therefore essential to understand the tendency for the likely occurrence of liquefaction in tailings dam as well as mechanics behind the behaviour of this tailing materials (inevitable products of ore mining, mineral and metallurgical processes). This study aims to present the mechanical behaviour and susceptibility to liquefaction of a gold tailings sample. Series of oedometer tests were conducted to determine the compression behaviour and the possibility of transitional behaviour or not. Index and physical tests were conducted to determine engineering grading descriptors which was directly linked to compression behaviour and comparisons made with other tailings. Microstructure was studied to understand the effects of fabric on the behaviour of samples and the chemical composition and mineralogy were also investigated. The compression paths slowly converge and the gold tailings might be said to be less transitional. The gold tailing is less dependent on initial state. The loosest gold tailing is more susceptible to liquefaction and compared to other gold tailings, this sample is less susceptible to liquefaction.

尾矿的力学行为和液化敏感性:黄金尾矿案例
尾矿坝溃坝可能导致生命损失、财产和资产毁坏或环境破坏,据信造成尾矿坝溃坝的重要因素是材料特性的力学和静态液化。因此,了解尾矿坝可能发生液化的趋势以及尾矿材料(矿石开采、矿物和冶金过程的必然产物)行为背后的力学原理至关重要。本研究旨在介绍一种黄金尾矿样本的力学行为和液化易感性。为了确定压缩行为和是否存在过渡行为的可能性,进行了一系列气压计测试。还进行了指数和物理测试,以确定与压缩行为直接相关的工程分级描述符,并与其他尾矿进行比较。对微观结构进行了研究,以了解织物对样本行为的影响,同时还对化学成分和矿物学进行了调查。压缩路径缓慢收敛,可以说金尾矿的过渡性较弱。金尾矿对初始状态的依赖性较小。最松散的金尾矿更容易发生液化,与其他金尾矿相比,该样本不易发生液化。
