Simulation prediction of mine water surges based on Visual MODFLOW

Mine water damage is a major threat to the safe production of coal mines in China, and how to predict mine water surges scientifically and effectively is an important basis for mine water damage accident prevention and protection of groundwater resources. This paper takes a mine field in northwest China as the research object, comprehensively grasps the geological and hydrogeological conditions of the mine and analyses the causes of coal seam water filling; applies Visual MODFLOW to establish a numerical model of groundwater flow in the study area, and carries out dynamic prediction of mine water influx under natural and artificial boundary conditions respectively based on the method of water conservation and coal mining. The results show that the water influx is significantly reduced under the modified boundary conditions, providing a strong basis for the selection of water-preserving coal mining methods and valuable experience for the mining of coal seams in areas with similar conditions.
