Numerical Simulation of Tailings Pond Dam Break Based on MIKE21
The safety of tailings pond not only affects the production benefit,but also affects the safety of people's life and property.Taking a tailings pond in Henan Province as an example,the numerical analy-sis model of tailings pond dam break is established using MIKE21 hydrodynamic module to simulate the evo-lution process of sand discharge flow.The submergence range,submergence depth and characteristic time point of the discharge sand flow under four different working conditions are compared,and the submergence characteristics of the discharge tailings after the addition of the sand bar are analyzed.The research results are of great significance for adding protective measures,preparing emergency plan and feasibility study re-port,designing safety facilities and so on.
