Abstract：Mine discharge is one of the main factors affecting the safety production of coal mine.It directly af-fects the complexity of mine hydrogeology conditions , and concerns the economic and technical evaluation of ore deposit, so the effective prediction of water yield of mine has become the priority in mine safety produc-tion.In order to effectively predict the water yield of mine, for the type of precipitation water-filled mine with the example of Gushuyuan Coal Mine,through the analysis of its rainfall and discharge data in recent 5 years, the quantitative relationship was derived using regression analysis.The average annual rainfall in the normal flow and high flow years was obtained through the hydrological frequency analysis of the rainfall in recent 20 years.Taking the average annual rainfall as the dependent variable and based on the inferred function relation-ship between precipitation and water inflow, the normal water inflow and the largest water inflow were predic-ted to achieve the purpose of effective forecasting.
