| 摘 要： | 本文讨论了大降深矿井排水预测中 ,利用迭代法求解数值模型时 ,地下水位计算误差的影响因素。利用理想模型讨论了地下水位计算误差与开采量、迭代收敛误差限、计算时间和含水量参数之间的关系。经讨论得知地下水位计算误差与迭代收敛误差限、计算时间和含水层参数有关 ,与开采量和水位变幅无关。

| Abstract: | The influential factors of calculation error for groundwater table are discussed by using the iteration method to find solution of numerical model in the mine drainage forecast of deep drawdown.The relationship between the calculation error of groundwater table and water discharge,the limit of iteration convergence error,the calculation time and the aquifer parameter using ideal model are studied.It is found that the calculation error of groundwater table is concerned in the limit of iteration convergence error,the calculation time and the aquifer parameter except the water discharge and groundwater table relief.An actual example is finally presented. |
