Quantitative analysis water inrush condition in north China mine floor by 3D numerical simulation
The main coal mine located on top of the limestone aquifers which include the thin Taiyuan group limestone aquifers and the thick Ordovician limestone aquifers in north of China. Ordovician limestone stratum as the main mine supply aquifers which with high pressure, rich of dynamic supply and static water storage, and the vertical geological structure(such as fault zone, karst column, etc.) as the main supply channel. the three-dimensional (3D) numerical simulation technique have more advantages than the traditional evaluation methods, It can more fully describe the complex internal structure of the aquifers, and handle a variety kind of system boundary. Therefore, 3D numerical simulation technique is an important tools to study mine hydrogeological.in this paper, took an application case that based on the limestone aquifer pumping test results in Gequan Mine Xingtai, Hebei province, used the software of Visual MODFLOW build a 3D description of aquifers. after calibration analysis model, Finally, obtained some Quantitative cognition about the mining hydro-geological conditions in the perspective of groundwater systems theory, This application provides a effective technology to guiding prevention and treatment of mine floor water, it has a strong theoretical and practical value for for mining deep coal in the north of China province.
