Abstract: With the increasing demand for coal resources driven by economic development, floor water inrush accidents have become more frequent during coal mining operations, significantly impacting mine safety production. Taking the floor water inrush accidents occurring in the floor of the No. 16 coal seam as the research object, this study first analyzes the formation causes of floor water inrush and the effect of water pressure on the floor in Xin’an Coal Industry Co., Ltd. (hereinafter referred to as "Xin’an Coal Mine"). Based on the characteristics of the mine, the analytic hierarchy process (AHP) and GIS technology were employed to screen water inrush risk factors, and a vulnerability analysis was subsequently conducted. According to the analysis results, technical measures for the prevention and control of floor water inrush are proposed.
