摘要
简述了金岭铁矿建设井下尾矿库的过程。根据尾砂特性分析 ,采用半承压水理论来计算密闭墙厚度 ,并利用疏干的方法解决尾矿水对周围水质的影响。 1999年投产后已向采空区排入尾矿 40余万t,各密闭墙体安然无恙 。
The process of constructing an underground tailings reservoir in Jinling Irom Mine is described.Based on the analysis of the tailings properties,half pressure bearing water theory was applied to calculate the thickness of the airtight walls and a drainage method was used to eliminate the effect of tailings water on the quality of surrounding water.Since its operation in 1999,over 0.4 million t tailings have been discharged into the mined area and the airtight walls have been in safe and there has been no water infiltration into the surrounding rock.
