Prediction of mine water inflow is important for the protection of mine safety .There are several methods for prediction of mine water inflow ,including the big well method ,mathematical statistics method ,artificial neural network method ,hydrogeo‐logical analogy method ,water balance method ,correlation analysis method ,and drawdown curve method of mine water inflow . Each of these methods has its own advantages and disadvantages .According to the hydrogeological conditions of the Lvtang coal mine in Guizhou province ,the big well method and water balance method were selected to predict the mine water inflow .At the same time ,the parameters which can affect the prediction results of mine water inflow were analyzed to ensure the accuracy of prediction results .The results showed that the general water inflow of the coal‐bearing stratum in the Lvtang coal mine is 210 L/s ,while the maximum water inflow can reach 410 L/s .This study can provide the scientific support for the prevention and control of mine water damage and safety in mine production .% 矿井涌水量预测对于保障矿山安全具有重要的意义.国内外常用的矿井涌水量预测方法有大井法、数理统计法、人工神经网络法、水文地质比拟法、水均衡法、相关分析法和涌水量降深曲线法等，这些方法都有各自的优缺点.综合考虑贵州绿塘煤矿的水文地质特征及资料情况，选取大井法和水均衡法对其矿井的涌水量进行预测，并对影响涌水量预测结果的参数进行了分析.预测结果显示：绿塘煤矿的一般涌水量预测值为210 L/s ，最大涌水量预测值为410 L/s.本研究可以为矿井水害防治和安全生产提供依据.
