摘要
通过对马家田尾矿堆积坝水化学场的分析 ,初步探讨水化学场的变异对尾矿的凝聚力和压缩性的影响 ,以及非饱和—饱和的氧化还原状态下Ca2 + ,Mg2 + ,SO2 -4离子和Fe (OH) 3 凝胶在尾矿颗粒间产生化学胶结的尾矿化学固结机理 ,并划分了 3个不同的化学固结分区 ,即化学固结增强区、化学固结相对稳定区和化学固结削弱区。
In this paper, through the analysis of water chemical field of Majiatian tailings fill dam, a preliminary study on mechanism of chemical consolidation of tailings with impact of the variation of water chemical field on their properties of the strength and deformation, in the state of oxidation-reduction of unsaturated-saturated has been performed. Three different chemical consolidation areas have also been delimited.
