华北石炭二迭纪煤田,在开发过程中地下水害问题十分突出,特别是象峰峰、焦作、井陉等老矿区,随着开采深度的加大,水害威胁越来越严重。煤层底板含水层,特别是中奥陶世石灰岩含水层的突然涌水,往往淹没矿井,或增加排水工作量。因此,研究底板突水条件,预测突水区域及突水点位,贯彻以防为主、综合治理的 In the North China Carboniferous Permian Coalfield, the problems of groundwater hazards are very prominent during the development. Especially in the old mining areas like Xiangfengfeng, Jiaozuo and Jingtao, as the mining depth increases, the threat of water damage becomes more and more serious. Sudden flooding of coalbed floor aquifers, especially the middle-aged Ordovician limestone aquifers, often overwhelms mines or increases drainage workload. Therefore, the study of the floor water inrush conditions, water inrush prediction and water points, the implementation of prevention-based, comprehensive management
