郭庄煤矿涌水量预测分析及防治水措施研究

Prediction and Analysis of Water Inflow and Study on Water Control Measures in Guozhuang Coal Mine

为了准确预测矿井涌水量,根据工作面的实际水文地质条件以及历年涌水量情况,采用大井法对工作面的涌水量进行预测。根据预测结果,设计帷幕注浆堵水方案及排水系统,建立完善的防治水措施,在郭庄煤矿17号煤层中进行实际应用。结果表明:正常期矿区的涌水量为100.31 m^(3)/h,丰水期矿区的涌水量为241.14 m^(3)/h,强排水系统的排水能力为1100 m^(3)/h,为井下安全开采提供了保障。

In order to accurately predict the mine water inflow,according to the actual hydrogeological conditions of the working face and the water inflow situation over the years,the large well method is used to predict the water inflow of the working face.According to the prediction results,the curtain grouting water blocking scheme and drainage system are designed,and the perfect water prevention and control measures are established.The actual application in the No.17 coal seam of Guozhuang Coal Mine shows that the water inflow of the mining area is 100.31 m^(3)/h in normal period,241.14 m^(3)/h in wet period,and the drainage capacity of the strong drainage system is 1100 m^(3)/h,which provides a guarantee for underground safe mining.
