Applications of MODFLOW in Quantitative Analysis Coal Seam Floor Water Inrush Condition

摘要：

In north of China, the main coal mine underlying the thin Taiyuan group limestone aquifers and the thick- ordovician limestone aquifers, ordovician limestone aquifers as the main supply aquifer which with high pressure, rich of dynamic and static water storage, and the vertical water-filled geological structure (such as fault zone, karst column, etc.) as the main supply channel, and take an application case, using simulation software Visual MODFLOW conducted a threedimensional(3D) numerical model to simulate the limestone aquifers and vertical geological structures, after calibration the model, obtained some quantitative cognition about the mining hydro- geological conditions in the perspective of groundwater systems theory, finally, and predicted the pumping rate in the different mining levels which be controlled by the vertical water-filled geological structure, for example, in ± Om level: the pumping rate is only 145.83 m3/h when there were no vertical water-filled geological structure (scenario 1), and the pumping rate should reach to 416 m3/h when the vertical geological structure conducting limestone aquifers water to the mining levels (scenario 2). in -ISO level: the scenario 2pumping rate more than 1200 m3/h.
