Abstract

The site selection of tailings dam is basis to ensure the safe operation in the later stage. Through numerical simulation, the influence degree of multiple topographic factors on the seepage field of tailings dam is analyzed, and it is found that the slope of bank slope on both sides of the valley, the longitudinal slope ratio of gully valley and the bottom width of gully valley will have a certain influence on the seepage field of tailings dam. In order to reduce the seepage line of the seepage field of the dam, the orthogonal optimization method was used to simulate the seepage field distribution of different horizontal drainage pipe diameters, pipe lengths, horizontal spacing, vertical spacing and buried inclination angles under different operating water levels based on the topographic factor analysis model. The results show that the infiltration line can be effectively reduced by the installation of the horizontal drainage pipe, and the pipe diameter, horizontal spacing and buried Angle can effectively reduce the height of the infiltration line. The mathematical model of the optimal horizontal drainage pipe is proposed, which provides a certain reference for the three-dimensional seepage safety analysis of the tailings pond.
