Simulation Study on Dam Failure Risk of Tailings Ponds Based on SPH Model
As a hazardous source with high potential energy,tailings ponds may experience dam collapse accidents,leading to mudslides and causing serious casualties and economic losses.The traditional depth integration method has limitations in simulating the evolution process of debris flows,while Smoothed Particle Hydrodynamics(SPH)is a new numerical simulation method that can compensate for the shortcomings of traditional methods.Taking a tailings pond in Panzhihua City as an example,a SPH model for dam failure debris flow is constructed to simulate the evolution process of debris flow under different working conditions,obtain flow data of debris flow,and study the influence of breach width and depth on the evolution characteristics of debris flow.The simulation results are in good agreement with the actual situation,so the SPH model can effectively simulate the dam failure risk of tailings ponds.The research results provide new methods for the safety management and risk prevention of tailings ponds,thereby ensuring the safety of people's lives and property and promoting sustainable development of the mining industry.
