摘要
为解决设备老旧、工艺落后、充填料浆质量没有保障等问题,以国内某在生产金属矿山技改扩能工程为例,对矿山现有充填制备系统工艺改造过程进行介绍。通过对尾砂浓密方式、料浆搅拌方式、料浆输送方式进行比较分析,提出充填制备工艺改造方案,并对充填能力、物料平衡及主要工艺装置进行计算和选型。实践证明:采用深锥浓密机的充填工艺能有效稳定底流浓度,实现稳态充填,且溢流水含固率较低。本文成果可为矿山技改扩能工程实施提供一定的技术方案支撑,也为国内同类矿山充填制备工艺选择提供一点参考。
In order to resolve problems such as the obsolescence of equipment,the backwardness of technology,and the lack of assurance regarding the quality of filling slurries,a case study is conducted on the technical transformation and capacity expansion project of a domestic in-production metal mine.The transformation process of the existing flling preparation system in this mine is introduced.Through a comprehensive comparative analysis of tailings thickening methods,slurry mixing approaches,and slurry conveying means,a transformation plan for the flling preparation process is put forward.Moreover,calculations and model selections are performed for the filling capacity,material balance,and main process equipment.Practical applications have demonstrated that the filling process incorporating a deep-cone thickener can effectively stabilize the underflow concentration,enabling steady-state filling.Additionally,the solid-content ratio of the overflow water is relatively low.The research findings of this paper can offer substantial technical-solution support for the implementation of the technical transformation and capacity-expansion project of the mine.Meanwhile,they can also serve as a reference for the selection of filling-preparation processes in similar domestic mines.
