Abstract: The risk maangement evaluation model of gas explosion is established based on analyzing the hazards that caused gas explosion in coal mine from the four aspects of people, machine,envrionment and management. The analytical hierarchy process method is adopted to obtain the weighted value of all factors and conduct fuzzy compreshensive evaluation on them, besides that, the results of risk management evaluation are quantified, so, the risk levels are obtained. The research results in this paper can provide some refenrence for the risk management work of all kinds of disasters and accidents in coal mine.
