摘　　要：为了考察平煤一矿丁6煤层硬煤、软煤不同的突出危险性预测指标临界值,使之更具有针对性和有效性,遂运用实验室瓦斯吸附解吸实验和理论分析相结合的研究方法,对实验数据进行统计分析并回归得出了瓦斯含量W和瓦斯压力p、瓦斯解吸指标V1和瓦斯解吸指标Q3、瓦斯解吸指标V1和瓦斯压力p之间的关系,最终基于瓦斯膨胀能确定了丁6煤层硬、软煤突出危险性预测指标瓦斯含量W和瓦斯解吸指标Q3的临界值,其中硬煤、软煤区域突出危险性预测指标瓦斯含量W的临界值分别为5.55、4.93 m3/t;硬煤、软煤工作面突出危险性预测指标Q3的临界值分别为0.20、0.26 mL/g。In order to inspect the different critical value of the outburst danger prediction index between hard coal and soft coal in the Ding6 coal seam for No. I Coal Mine of Pingdingshan Mining Group, it made the prediction more targeted and effective. It used the re- search methods with the combination of the experiment of gas adsorption and desorption in the laboratory and theoretical analysis to con- duct statistical analysis for experimental data, it carried out regression analysis and obtained the relationship of gas content W and gas pressure p, gas desorption index V1 and Q3, gas desorption index V1 and gas pressure p, finally determined the critical values of gas content W and gas desorption index Q3 of hard and soft coal outburst danger prediction index in the D6 coal seam based on gas expansion energy. The critical values W of outburst danger prediction indexes of hard and soft coal were 5.55,4.93 m3/t. The critical values Q3 of outburst danger prediction indexes of hard and soft coal were 0.20,0.26 mL/g.
