鲁西煤矿开采17~#煤奥灰含水层疏降水量预测研究

Study Prediction of Dewatering Quantity from Aquifer in Ordovician Limestone during No.17 Seam Mining in Luxi Mine

针对鲁西煤矿下组煤底板的突水危险性,利用传统的地下水动力学的理论计算和地下水数值模拟两种方法对奥灰含水层的疏水量进行了预测,并对这两种疏水量预测方法的优缺点进行对比,结果表明,基于GMS的地下水数值模拟预测的结果更加符合实际情况,可为矿井抽、排水系统的布置提供了依据。

To eliminate the risk of water inrush of coal floor in Luxi coal floor,theoretical calculation based on traditional groundwater dynamicsand numerical simulation of groundwaterwere applied to predictthe dewatering quantityof Ordovician limestone aquifer,and the advantages and disadvantages of the two methods were compared. The results show that,thesimulation of groundwaterbased on GMS fit the actual situation better. The study could provide basis for the arrangementof mine drainagesystem.
