Abstract: The mathematical deformation model of tailing deposits is established by using the relationships among the stressporosityand fluid concentration. The characteristics of porosity change in the tailing deposits are based on the mechanical performance and the dynamic leaching test results. This coupled model tailing deposit model with the coupling of stressseepagechemical interactions is also consider the effect of acid solutions.
