Due to the complexity of geological conditions,dynamic changes in climate,and the diversity of field surveys and calculation methods,the calculation and prediction results of water inflow in underground coal mines have great uncertainty.To simplify the difficulty of calculating water inflow in mines and reasonably determine the available water volume in changing environments,this article focuses on mines with periodic and stable operating modes,combined with actual production conditions and needs,Based on the theory of dynamic water balance,an empirical formula for calculating the water inflow of underground coal mines and pits is proposed.The analysis results can provide technical references for alleviating the contradiction between water supply and drainage in mining areas,scientifically treating water resources in mining areas,and managing water resources.
