摘要
通过对安徽祁东煤矿新生界底部含水层("四含")的水文地质条件分析,建立了水文地质概念模型和数学模型。运用V isualM odflow软件对模型进行识别和验证,从而识别出"四含"内部参数特征。运用识别后的模型采用两种方案对"四含"进行疏放,结果表明:"四含"在一定时间内是能够疏干的,方案2的时间效益优于方案1,这为"四含"水害的防治、煤岩柱类型划分与高度的合理留设提供一种重要的参考依据。
Hydrogeologic conception model and mathematical model were built, on the basis of analysis of hydrogeolgic conditions of the aquifer situated in the bottom of Cenozoic strata （＂the fourth aquifer＂）. The model was identified and verified by software visual modflow and some inner characteristic parameters of the aquifer were gained. The discharge from the aquifer was simulated according to two different discharge scenarios. The results showed that the storage quantity of the aquifer can be drained out completely in certain period of time and the first scenario is better than the second. The research provides some important references for water prevention of the aquifer, classification of coal-rock pillar and suitable allocation of its height.
