Study on Discrimination Model of Water Inrush Source in Binhuang Mining Area of China

Groundwater flow into the mine by coal mining, which threatens safety of mine. Therefore, it is necessary to identify source water flowing Taking binhuang mining area in Shaanxi Province as research background, discrimination models six inrush sources had been studied. The composition 256 samples was determined and quality characteristics 6 were analyzed. Fisher linear discriminant function model established selecting 9 indexes components. By testing effect, considered that probability K1L aquifer misjudging Q surface high, misjudgment rate 30.4%. Combined with analysis geological conditions, has a good hydraulic connection water. Aiming at problem misjudgment, neural network used, reduced 0%.
