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。
Based on the analysis of the chemical field of the tailings dump dam in Majitang, the effects of variation of the hydration field on the cohesion and compressibility of the tailings, as well as the effects of Ca2 +, Mg2 +, and SO2 - in the unsaturated-saturated redox state, 4 ions and Fe (OH) 3 gel produced tailings chemical tailings tailings chemical consolidation mechanism, and divided into three different chemical consolidation zones, namely chemical consolidation enhanced zone, the chemical consolidation is relatively stable Area and chemical consolidation weakened area.
