摘要
石门揭煤突出预测指标主要有两种:综合指标D,K和初始释放瓦斯膨胀能指标.为了比较两种指标的优越性,通过现场钻取煤样,在试验室对其进行测定,并利用灰关联分析方法进行指标优选.分析结果表明:初始释放瓦斯膨胀能反映煤与瓦斯突出危险性的准确程度要高于综合指标D和K值.因此,预测马家沟矿突出的最好指标是初始释放瓦斯膨胀能.
There are two indexes of outburst forecast mostly when a cross-cut is uncovered:general index D and K,expansion energy in initial released gas.In order to compare advantages of above indexes,coal samples were collected by drilling in situ,and tested in laboratory,then according to grey relevancy analysis method,indexes were optimized.Analyse results show that nicety degree for reflecting coal and gas outburst fatalness of expansion energy in initial released gas is higher than that of general index.Therefor...
