Short summary
In recent years, dam-break accidents in tailing ponds have happened frequently, which has resulted in verified loss of life and ecological disaster. Simulation of a tailing dam accident in advance is useful for understanding the tailing flow characteristics and assessing the possible extension of the impact area. In this paper, a 3-D CFD approach was proposed for reasonably and quickly predicting the flow routing and impact area of mud flow from a dam failure across 3-D terrain.
