摘要
Coal mine water hazard is one of the five major disasters, especial y for the mining area in North China Karst 9# coal mine, Coal Seam Floor Water strong Ordovician aquifer would pose a huge threat to mine safety. In fact, al major coal mine water inrush occurred before, except for some visible sign of, but also includes non-visible sign, namely, water inrush Hydrogeochemistry implied. If you can capture and use this information in a timely manner to carry out analysis of hydrogeochemical characteristics, for identifying sources and determine the possibility of water inrush occurred has important practical significanceFuzzy identification method and the above two methods, is more suitable for coal mine water inrush identification. Discrimination results from the side reflects the Ordovician limestone aquifer and the limestone aquifer Daqing Chemical Characteristics of relatively independent, indicating that the two wel s in the Ge Quan-east aquifer hydraulic connection weak. Ordovician limestone aquifer and the Benxi limestone aquifers have some similar chemical characteristics, showing the Ordovician and the Benxi limestone aquifer has a hydraulic connection.
