SUN Bin~(1,2)(1.School of Management,China University of Mining and Technology,Beijing 100083,China;2.Department of Safety Control,Zhejiang College of Police Officer,Hangzhou 310018,China)  
Base on the safety engineering principle and the site investigation and according to the present status of the mine gas prevention and control,the paper provided the conception of the mine gas existing dangerous source.The paper holds that the gas emission and gas pressure would have the features of mine gas existing dangerous source.The variation of the gas value within an investigation week would be non linear issue and the gas existing dangerous source would have non linear dynamic features.The gray related method can be analyzed the gas caused dangerous source affected to the existing dangerous source and relationship between the factors of the existing dangerous sources and the caused dangerous source.With the gas emission,ventilation quantity,gas content and other parameters,the gray related method can analyze the dangerous degree of the gas dangerous source in the mine roadway,which would have certain reference value to prevent and control gas explosion in mine.
