Abstract：Water inrush accidents in the roof aquifer occurred many times in the working faces of No. 8 coal seam in West No. 1 mining district in Pansan Mine. In order to ensure the safe mining of other working faces of this seam, a numerical simulation model of underground water in the study area was established with the Visual Modflow software based on the analysis of the hydro-geological and geological conditions in this area, and with this model, prediction was made on the water inflow in four working faces of No. 8 seam in West No. 1 mining district in the mine under the natural mining conditions, which provided basis for taking appropriate water drainage plans in the process of mining.
