Discrimination of Mine Water Bursting Source Based on Fuzzy System
Through applying the background values of aquifer derived from fuzzy clustering analysis,a fuzzy comprehensive estimation model was developed for quick recognition of mine water inrush.Based on the hydrological-chem ical analysis data of water samples which water bursting sources were known in Liliu mining area,Shanxi province,this paper presented that the hydrological-chemical characters of different aquifer was different,and established a sort of fuzzy comprehensive evaluation models of discriminating coal mine water bursting sources in Liliu mining area.Applied to a production mine,the correct rate of water bursting source judged results by various methods was more than 70%.With the dispersion method and the method extracted from stepwise discrimination analysis to determine the membership degree and Model 3 the type determined by various factors,the correct rate of water bursting source with comprehensive evaluation of combination of two methods was higher respectively 94.5% and 93.3%.The fuzzy system can efficiently and accurately discriminate the resource of water inrush for an unknown sample,and provide the decision basis for the safety production of the coal mine.
