摘　　要：通过现场钻取煤样,在试验室测定了2种石门揭煤突出预测指标:综合指标和初始释放瓦斯膨胀能指标,利用灰色系统理论进行指标优选,发现了马家沟矿最佳的突出预测指标———初始释放瓦斯膨胀能。The coal samples are collected by drilling in situ, and two indexes of outburst forecast when a cross - cut is uncovered-general index and expansion energy in initial released gas, is tested in laboratory, according to the theory of grey system, indexes are optiraized, we find that expansion energy in initial released gas is the best index of outburst forecast when a cross- cut is uncovered in MaJiaGou mine.

关 键 词：突出预测 综合指标 初始释放瓦斯膨胀能 灰色优选
