Kaiping Coal Seam Exploitation SongGuYing Exploration District Water Filling Factor Analysis

Based on the SongGuYing exploration hydrogeological conditions,including water-resisting layer characteristics,dynamic groundwater and each aquifer of hydraulics relations between the analysis of factors,for mine mining flood prevention and control reference material and decision-making basis.Coal seam mining directly affect mainly for the main water filling aquifer recognize base-level cycle of roof and floor,and coal seam between the upper tertiary middle and bottom aquifer,sandstone half cemented sands,in local conglomerate only for direct water filling aquifers.Mr Grey aquifer on 144.38 ~ from 12 coal seam 150.81 m,there is thick layer silty sandstone and mudstone water-resisting layer,under normal circumstances,Mr Grey water will not pose a threat to coal seam mining,combined with adjacent area money home camp mine hydrogeological data comparison,exploration district deposit hydrogeology type except fault guide water outside for hydrogeological conditions of fracture pore medium(local) water filling deposits,namely: the category of type ii.
