Abstract

Some residential areas and factories are located downstream the tailings pond. Once the tailings dam collapsed, the consequence will be very serious, so perfect prevention and emergency preparedness work is critical. And the prediction of tailings dam collapse affecting consequence is an important basis for the work. To improve the predictive accuracy of tailings dam break consequence, accurate topographic boundary data is necessary. Thus, precise terrain scanning was implemented by using 3D laser scanner for the tailings pond and downstream. Then higher precision digital elevation model was generated after the process of three-dimensional points cloud data denoising, splicing and modeling. On this basis, combining with the tailings dam geological prospecting and design data, the numerical model of dam break flow was set up. As a result, the residential area and the farmers' market planned to build were completely destroyed once the tailings dam break. With the calculation based on the 3D points cloud data, scientific decision basis can be provided for related departments.
