Analytical techniques for mine water inflow estimation

Dear friends, We are constructing borewells in the area surrounded by mines. Can someone explain different analytical techniques for mine water inflow estimation incorporating several refinements, such as finite boundary conditions, linear, fracture and turbulent flow conditions? These methods will help us do groundwater modelling for our area. Your help would be much appreciated. If you have practically applied any of the techniques, please share your experince of adopting that particular technology.  Best.
