Abstract：In order to study the impact of mining in Jiulong mine on groundwater resources, this paper used the methods of theoretical calculation, data analysis and water level observation and analysis to calculate the groundwater impact area in Jiulong mine. The maximum height of water conduction fracture zone was 64.77 m and the maximum height of caving zone was 16.02 m. It showed that under the current conditions, the mining of Jiulong Mine had a serious impact on the sandstone aquifer of the Lower Shihezi Formation, the sandstone aquifer of the large coal roof, the Yeqing limestone aquifer and the Daqing limestone aquifer, and had a slight impact on the Quaternary aquifer and the Ordovician aquifer under the coal seam.
