In mining operations, tailings ponds are essential engineering structures that contain substantial quantities of tailings and waste. Therefore, ensuring their stability is crucial for operational safety and environmental protection. This study aims to validate the effectiveness of various design measures for tailings ponds to enhance their design and management. Using GEO-SLOPE numerical simulation, we conducted a comprehensive assessment of the seepage and stability of tailings ponds under different scenarios.The results demonstrate that, under a 500-year flood event, the drainage capacities of the east and west interception ditches and the overflow channels of the tailings pond comply with the required standards. Moreover, seepage analysis confirms the effectiveness of the seepage control measures implemented in the tailings dam design, particularly the use of HDPE geomembranes and the design drainage system, in providing superior seepage prevention. Furthermore, stability calculations under three different conditions indicate that the downstream slope stability of the tailings dam meets the design standards.Additionally, this study suggests the installation of manual and online monitoring facilities to enable real-time monitoring of the tailings dam body and drainage conditions, thereby mitigating the risk of unforeseen incidents. In conclusion, these findings offer valuable technical references for the future design, construction, and management of tailings ponds, thereby advancing the technology and application of tailings pond stability analysis.
