Scenario modeling of groundwater filtration in a enclosing tailings dam of a mining enterprise

Abstract

Scenario hydrogeomechanical 3D modeling of groundwater filtration through the body of the enclosing tailings dam of a mining enterprise was carried out. A hydrogeomechanical 3D model of the tailings dam was created and modeling of filtration-deformation processes was carried out according to three scenarios for the position of the depressed surface of groundwater: the actual state, the limit according to the project, and the maximum filling with water. The calculated values of the rate of water filtration through the body of the enclosing dam are determined for the simulated scenarios of the position of the depression surface. A graphical dependence of the filtration rate on the position of the depression surface of groundwater is revealed, and an analytical expression approximating it is found.
