| Coal mine water hazard is one of the five major disasters, especially 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, all 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 significance.Jizhong Energy Co. coal-mining 9# East Mine for the study, mainly through water-filled mine water hydrology geochemistry analysis, the selection of representative Na++K+,Ca2+,Mg2+,Cl-,SO42-,HCO3- and TDS such as the evaluation index, using the gray, fuzzy comprehensive evaluation and BP neural network theory and methods to construct the mine suddenly (a) water, rapid identification system.Test results showed that the three methods of consistency and diversity, reflecting the advantages and disadvantages of various identification methods.Fuzzy 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 wells 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.Comprehensive use of the above methods, operating software with visual VB, the successful completion of Inrush Water Source System Development for the Handan area is karst mining under high pressure to provide a scientific basis.
