应用灰色关联分析法评价瓦斯爆炸事故危险源

基于安全工程学原理和现场调研，针对矿井瓦斯防治现状，提出瓦斯固有危险源概念，认为瓦斯涌出量、瓦斯压力具有瓦斯固有危险源特征；瓦斯涌出量在一个考察周期内，变化属于非线性问题，瓦斯固有危险源具有非线性动力特征；瓦斯诱发危险源对固有危险源影响以及固有危险源和诱发危险源这些因素之间的相互关系可用灰色关联分析。采用瓦斯涌出量、风量、瓦斯浓度等参数，运用灰色关联分析实例分析巷道瓦斯危险源风险程度，对现场防治瓦斯爆炸有一定参考价值。

Gray related analysis method to assess risk of gas explosion accident dangerous source

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.
