| 摘 要： | 定量分析和研究废弃矿井淹没过程的水流特征对于预测和防止废弃矿井地下水淹没过程中诱发的次生灾害具有重要意义。建立了废弃矿井淹没的多种介质水流数学模型，得出了淹没补给水量随时间、矿井内淹没水位和补给水源含水层水位之间的相关关系，建立了淹没补给水量与相关影响因素之间的函数关系式，完成了矿井淹没过程中涌水量实时计算的FEFLOW模块设计和开发。进行了近水平煤层开采后废弃矿井充水淹没水位回弹过程的数值模拟计算，得到了不同充水介质在充水淹没过程中的水流和水位回弹特征。结果显示，FEFLOW二次开发模块运算效果良好，具有实用价值。

| Abstract: | When a mine is abandoned,dewatering stops.The inflow from water floods roadways,mining crack fracture system,and then overflows the aquifer where the water had been drained when coal was mining.Thus the groundwater rebound was in abandoned mines.Quantitative analysis and study on flow characteristics during water flooding are important for forecast and prevention of secondary disasters caused by water rebound process.Numerical model for multimedia of groundwater rebound in abandoned mines was established,an... |
