| Our country is that great power of mining industry, the industry mine such as the metallurgy industry, nonferrous metals industry, chemical industry, nuke industry, building material and light industry all has tails facilities. The safe of tailings dams is related to the environment and human being's safety directly. The more precise computationdebris for tailings dams' seepage field to be allowed debris dams' security.The analysis of the seepage in tailings dams is a complicated question for coupling seepage-consolidation. This article studys the basics of the seepage field and stability analysis in a tailings dam.This article start off the basic theory about seepage, be tied in wedlock actual project, main study transfusion characteristic and influencing factor in tailingss dam, detailed analytical saturation line with tailings dam in different beach length, slope ratio of upper reaches, slope ratio of lower reaches, the coefficient of permeability in every tier tail ore sand and the coefficient of permeability in seepage exit.This article studys coefficient of permeability and builds the expressions under the efficiency of consolidation in the basic of the the theorys which have studied, builds the programmes with the expressions on Matlab software platform.This article also ananlyses a representative model with this theory and expressions and the programmes.LiXi tailings dam is a representative dam which builds by upriver method.In this article, collects the data of terrain and coefficient of permeability, density, angle of friction and pore ratio and so on. Makes a analyse ues the programmes, and makes analyse about seepage with Geo-Studio which is a geo FEM programmes.An attempt on the development and improvement of calculation seepage filed is presented. All these have the theoretical meaning and applicable value,and also present usefui reference to the slope stability analysis design for the tailings dams and slop control etc.
