信湖矿水文地质条件分析及涌水量预测研究

Analysis of hydrogeological conditions and prediction of water inflow in Xinhu Mine

基于信湖煤矿水文地质条件,利用数值法和地下水动力学方法分别进行矿坑涌水量预测,并就预测结果进行对比分析,结果显示:利用数值模拟法预测得到的信湖矿的矿坑涌水量为11 000~3 236 m^3/d,水动力学方法得到的信湖矿的涌水量为13 152 m^3/d,两种预测方法所测算出的结果偏差不大,总体认为数值法的计算结果比较可靠。同时可将水动力学法当做数值法计算矿坑涌水量预测的一种检验印证方法,两种计算方法结合起来会使矿坑涌水量的预测结果更加准确。

Based on the hydrogeological conditions of Xinhu Coal Mine, the numerical simulation and groundwater dynamics method were used to predict the mine water inflow, and the results were compared. The results show that the mine water inflow from Xinhu Mine predicted by numerical simulation is 11 000~3 236 m^3/d, the water inflow from Xinhu Mine obtained by hydrodynamic method is 13 152 m^3/d. The results calculated by the two prediction methods are not much different. It is generally considered that the numerical method is more reliable. At the same time, the hydrodynamic method can be used as a test method to calculate the prediction of mine water inflow by numerical method. The combination of the two calculation methods will make the prediction result of mine water inflow more accurate.
