摘要
The analysis of hydrogeological characteristics on the basis of the mine water filling factors were discussed. It is considered that the sandstone of Shanxi group and the third limestone of Taiyuan group are direct aquifer for mining coal which has a direct impact on the coal seam mining. The groundwater dynamics of the “big well method” for mine water inflow is forecasted. Mine inflow in coal mine is conducted to predict the result of 286 m3/h (normal flow of water) and 405 m3/h (maximum flow of water) through “big well method” contained by underground hydrodynamics,providing significant foundation and reference value for safe production of Wanfu minefield,even other coal mines.
