摘　　要：为考察钻屑瓦斯解吸指标△h2、钻屑瓦斯涌出初速度qm以及钻屑量指标Smax对某矿煤与瓦斯突出预测的敏感性,运用了灰色关联分析法和临界值迫近度分析法,对这三个指标的实测数据进行了分析处理,比较其突出危险敏感性的大小,找到突出预测敏感指标,以提高预测预报的可靠性。In order to compare the sensibility of forecast on coal and gas outburst ured data of desorbed index of drilling filings gas,discharging initial velocity of drilling in a mine, measfilings gas and index of drilling filings amount are analyzed by using gray relating analysis method and closeness degree to critical value analysis method to compare the sensibilities toward risk of coal and gas outburst, forecast sensibility index of outburst is found, to increase the reliability of forecast.
