Abstract: 

Prediction of groundwater inflow into a mining excavation is important during the feasibility stage of a surface mining operation. An effective drainage scheme will necessarily allow mining to be carried out in dry conditions and improve the slope stability; reduce many environmental problems and reduction of corrosion of mining plant and equipment. Analytical solutions are based on some assumptions and special boundary conditions that limit their applicability in different mining situations. On the other hand, numerical models are powerful tools to simulate all aquifer conditions and can provide a more realistic representation of the interaction between groundwater systems and mining excavations. Numerical models can reliably predict the quantity of inflow into a surface mine excavation. A two-dimensional numerical finite element model called SEEP/W has been used to predict inflow of water into surface mine workings and to design an appropriate dewatering system. The SEEP/W model considers the Galerkin approach in order to determine an approximation solution for the governing equation of the groundwater flow by the finite element method. The SEEP/W soft ware has a capability to simulate saturated/unsaturated flow conditions, confined/unconfined flow and to calculate the height of the seepage faces of the excavation. The results of the numerical model are compared to those from analytical solutions as well as other existing numerical models for estimating groundwater inflow into a surface mine. The results of the model presented here can provide valuable information to design dewatering systems.
