Numerical Simulation and Prediction Assessment of Floor Water Inflow in Tiexin Coal Mine

A numerical model for groundwater of Tiexin Mine was set up with the numerical simulation software Visual Modflow for groundwater according to the geological structure and hydrogeological conditions in order to ensure the safe production of the mine.The model can better reflect the groundwater flow field in the mine after it was identified and verified,be used to predict the water inflow under different mining conditions of the mine,and thus provide the basis for the formulation of the mine water drainage scheme.
