摘　　要：通过分析丰汇煤矿15号煤层瓦斯含量和瓦斯压力与埋深的关系,初步确定煤层瓦斯含量为区域预测敏感指标,将区域预测数据标准化并利用数学分析方法,通过样本数据的极差和标准差进一步确定区域预测敏感指标为煤层瓦斯含量,以《防治煤与瓦斯突出细则》为参照,利用初始释放瓦斯膨胀能指标校准计算预测敏感指标的临界值,最终确定丰汇煤矿15号煤层的突出危险性区域预测的敏感指标为煤层瓦斯含量,其临界值为7.83 m^(3)/t。By analyzing the relationship between gas content,gas pressure and buried depth of No.15 coal seam in Fenghui Coal Mine,it is preliminarily determined that the gas content of coal seam is the sensitive index of regional prediction,the regional prediction data is standardized,and the mathematical analysis method is used to further determine that the sensitive index of regional prediction is the gas content of coal seam through the range and standard deviation of sample data,with reference to the detailed rules for the prevention and control of coal and gas outburst,using the initial released gas expansion energy index to calibrate and calculate the critical value of the predicted sensitive index,it is finally determined that the predicted sensitive index of the outburst risk area of No.15 coal seam in Fenghui Coal Mine is the coal seam gas content,and its critical value is 7.83 m^(3)/t.
