Abstract: In order to adapt to the trend of digital and visual mine management,to improve the management level of tailings ponds,the actual production problems are solved based on 3Dmine mining engineering software.By means of tailings pond data,a 3D model of the tailings pond was built to solve practical problems such as analysis of storage capacity,calculation of dam volume,estimation of solution volume and tailings volume,optimization of tailing discharge plan.The application of engineering examples achieves the expected effect.This study means significant to the practical problems of tailings pond production for those similar mines.

Key words: tailing pond,3D model,storage capacity,engineering quantity
