对突出矿井进行危险等级划分，并实行分级管理，可减少防突工程量、减少防突的盲目性，具有非常显著的社会和经济效益。作者将突出矿井划分为严重、中等、较弱3个等级，选取12个指标综合评判矿井的突出危险等级。在分析分级指标并进行量化的基础上，采用模糊数学的多因素二层次综合评判方法，建立决策模型，按最大隶属原则，确定矿井突出危险等级。运用所建立的模型，对一些突出矿井进行了分析，证判的分级结果与实际情况相吻合。

managing the coal mines according their dangerous grade determined. can decrease the engineering quanity and lessen the sightless characteristic. It has marked benefit for community and great economic benefit. The dangerous grade of outburst mines are determined Outburst coal mines are classified into mines with serious outburst hazard, mines with middle outburst hazard and mines with ordinary outburst hazard. Twelve classification indicators are used in comprehensively evaluating the dangerous grade of outburst mines. The dangerous grade of outburst mines are determined according to the principle of the most subjection with fuzzy comprehensive evaluation method, on the basis of the classification indicators and its quantification. By the model founded, some coal mines are studied and the research results are accordant with the fact.
