“…The tailings pond represents a high-risk source of potential energy, and in the event of a dam breach, it could result in significant downstream damage.The research on tailings dam failures primarily encompasses two aspects: the instability of the dam structure and the evolution of debris flows.The study of dam break sand flow evolution primarily encompasses the empirical formula approach, model testing methodology, and numerical simulation techniques. In terms of dam break research, Yekti et al 1 simulated that overtopping is the most dangerous, with the highest flow velocity and flow rate. Chen et al 2 simulated the development of notch erosion using the time iteration method in mathematical models.…”

In response to the challenges posed by rapid development, wide-ranging disaster impact, and untimely warning of debris flow resulting from tailing dam failure, it is of great significance to study the mechanism of dam failure as well as the evolution law and affected area of debris flow for effective disaster prediction and risk assessment. Establish a 1:150 physical model for tailing dam failure test and combine it with RAMMS debris flow software to study the mechanism of tailing dam failure and the evolution law of rock flow in complex environments. By analyzing and comparing experimental data, the consequences of disaster risk following dam failure were summarized in a comprehensive manner. The results show that: The particle size distribution of the model sand should be moderate; The composition of particle size distribution has a significant impact on the collapse morphology of dam body after dam failure. The saturation line is the lifeline for tailing reservoir stability, and its level determines the degree of tailing saturation in the reservoir. The breach is situated at the midpoint of the dam crest. When the breach occurs, the inflow volume is 0.313m3. According to the flow ratio relationship, the inflow volume at breach occurrence is equivalent to 1.78 times the total amount of a 1000-year flood and 1.19 times the total amount of a probable maximum flood (PMF). The analysis of the surface flow field reveals that the region with the highest flow velocity extends from the dam toe to Shangdi village; The impact on Shizhou village is limited to the backwater of the dam break water flow and gradual sedimentation of tailings.

In response to the challenges posed by rapid development, the wide-ranging disaster impact, and the untimely warning of debris flow resulting from tailing dam failure, it is of great significance to study the mechanism of dam failure as well as the evolution law and affected area of debris flow for effective disaster prediction and risk assessment. We developed a 1:150 physical model for testing tailing dam failure and combined it with RAMMS (V1.7.0) debris flow software to investigate the mechanisms of tailing dam failure and the evolutionary patterns of rock flows in complex environments. Through the analysis and comparison of experimental data, we comprehensively summarized the consequences of disaster risk resulting from dam failure. The results show that the grain size distribution of the model sand should be moderate; the composition of the particle size distribution has a significant impact on the collapse morphology of the dam after failure. The saturation line is the lifeline for the stability of the wake reservoir, and its level determines the degree of saturation of the wake in the reservoir. The breach was at the midpoint of the crest of the dam. The inflow volume at the time of the breach was 0.313 m3. According to the flow ratio relationship, the inflow volume at breach occurrence was equivalent to 1.78 times the total amount of a 1000-year flood and 1.19 times the total amount of a probable maximum flood (PMF). Analysis of the surface flow field revealed that the region with the highest flow velocity extended from the toe of the dam to Shangdi village; the impact on the village of Shizhou was limited to the backflow of the dam break and the gradual sedimentation of the tailings.
