Abstract：In order to predict the influence of the extraction of No. 3 coal seam upon the overlying aquifer in Xiangyuan Coal Mine, the second-type flow boundary was determined by analyzing the hydro-geological conditions in this coal mining area, using Visual Modflow software and subdividing the computational domain, and the influence of the extraction of No. 3 coal seam on the overlying aquifer in this mine was simulated and predicted by using the iterative approximation method. The results showed that after the coal mining of the mine for 12. 6 years, the fall depth of water level at the funnel center was about 87 m and the influenced area was about 31. 85 km2 .
