镇平县铜钼选矿厂尾矿库地质灾害隐患分析及治理措施

Risk analysis and control measures of geological hazards from Cu–Mo mineral separation tailing ponds in Zhenping county

河南省镇平县铜钼选矿厂尾矿库已运行数十年,目前存在多处隐患,严重威胁下游水库及32万人口饮水安全。阐述了尾矿库的地质环境背景,分析了地质灾害隐患类型及特征,提出了尾矿库治理、拦渣坝及沉淀渡槽、地下水源修复等工程措施。

Tailing ponds of copper-molybdenum mineral separation in Zhenping county, Henan province, have operated for decades. The ponds present several hazards and pose a serious threat to downstream reservoirs and to the safety of drinking water for an estimated population of 320,000 people. This article examines the geological-environmental background of tailing ponds, and analyzes the types and characteristics of geological hazards that the ponds present. The study proposes several engineering measures, including tailing pond treatment, blocking of the dregs dam, precipitation aqueduct engineering, and groundwater restoration engineering.
