Taking A Coal Mine as an example,a gas hazard warning model was proposed,and the application effect of the proposed model was verified through practical application.This model conducts over limit warning analysis and dynamic trend warning analysis by collecting environmental data such as blasting,ventilator failure,drilling and hole spraying,roof caving,coal and gas outburst,and gas emission in goaf,etc.At the same time,the Fisher discriminant method was used to compare the analysis results and determine whether there is a gas hazard in the underground working face of the coal mine.The application effect analysis shows that the warning model performs well,and has successfully warned the hidden dangers of gas disasters for 5 times,and the accuracy rate can reach 100%.This indicates that the gas hazard warning model has high application value and can be widely promoted and used on a large scale.
