Modeling And Simulation Of Mine Water Drainage

This paper discusses a model for groundwater quantity prediction at operating sections of underground mines. The approach involves the development of a mathematical model for the movement of water through an integrated (unsaturated-saturated) flow domain within a definable watershed. The model is programmed for the IBM 370/168 computer using the method of finite difference approximation coupled with a finite element analysis. The conceptual and computational aspects of the model have been validated with both experimental and field data and applied to an active coal mining operation located in central Pennsylvania.
