摘　　要：为探究突出煤层区域预测瓦斯含量临界值,采用理论计算初步确定煤层瓦斯含量临界值为6.0 m^(3)/t,并采用“三率”分析法和瓦斯含量与突出危险的关联性对瓦斯含量临界值进行了分析,最后对确定的区域预测瓦斯含量临界值进行了扩大验证,从而最终确定3#煤层区域预测瓦斯含量临界值为6.0 m^(3)/t合理有效,为矿井安全生产提供了保障。In order to explore the critical value of regional predicted gas content in outburst coal seam,the critical value of gas content in coal seam is initially determined to be 6.0 m^(3)/t by theoretical calculation,and the critical value of gas content is analyzed by using the"three rate"analysis method and the correlation between gas content and outburst risk.Finally,the determined critical value of regional predicted gas content is expanded and verified,therefore,it is finally determined that the critical value of the regional predicted gas content in the 3#coal seam is 6.0 m^(3)/t,which is reasonable and effective,and provides guarantee for the safe production of the mine.
