Abstract
During long-term operation,tailings dam bodies in lead-zinc mining areas are prone to seepage failure and slope instability risks due to factors such as complex geological conditions,rainfall infiltration,and fluctuating reservoir water levels.To ensure the safe operation of tailings storage facilities,this study conducts qualitative and quantitative evaluations of the dam's stability under various working conditions using the limit equilibrium method and coupled seepage analysis.Based on an analysis of the natural conditions of a mining area and the material composition,physical-mechanical properties of the tailings dam,the study identifies potential sliding surfaces and safety factor variations.For identified safety hazards,comprehensive remediation measures are proposed,including drainage and seepage control,widening and thickening of the dam toe,slope road reinforcement,and ecological restoration.The research findings provide technical references for improving the stability of lead-zinc mine tailings dam bodies and risk prevention.关键词
