利用数值法和解析法对祁南煤矿矿坑涌水量进行预测分析

Numerical and analytical methods of the water inflow in qinan coal mine

以祁南煤矿为例,详细分析了其水文地质条件,利用两种计算方法(数值法和解析法)对矿坑涌水量进行了预测研究,并将观测数据与计算结果进行了对比分析,总体认为数值法得到的预测结果比较可靠。另外,在计算矿坑涌水量的过程中,解析法可以当做数值法的补充验证方法。两种预测方法相互结合,计算得到的矿坑涌水量更加可靠。

Taking Qinan coal mine as an example,the hydrogeological conditions are analyzed in detail,two calculation methods(numerical method and analytical method) are used to predict the water inflow of the mine,the observed data are compared with the calculated results.It is generally believed that the prediction results obtained by numerical method are relatively reliable.In addition,the analytical method can be used as a supplementary verification method in the calculation of mine water inflow.The two prediction methods are combined with each other,with the calculated water inflow is more reliable.
