摘　　要：为筛选出煤与瓦斯突出危险性预测敏感指标,通过对通顺煤矿2~#煤层4组煤样的吸附平衡实验数据拟合得出了2~#煤层吸附平衡压力p与钻屑瓦斯解析指标Δh_2和K_1之间的函数关系式,再通过模糊聚类分析同一工作面不同测点的钻屑瓦斯解吸指标K_1和Δh_2、钻屑量S,得出Δh_2的相对敏感度最大,所以选取Δh_2作为通顺2~#煤层煤与瓦斯突出危险性预测的敏感指标,K_1和钻屑量S作为辅助性的参考指标。In order to screening risk prediction of coal and gas outburst sensitive indexes,firstly, obtained a function relation between adsorption equilibrium pressure p and drilling cuttings index K~ and Ah2,through experimental fitting of adsorption equilibrium experimental date of 4 groups of samples of coal seam 2# of Tongshun mine,secondly,obtained drilling cuttings index Ah2 has the maximum sensitivities by fuzzy clustering analysis the same face＇s different measuring point of drilling index S for K1 and Ah2,So choose Ah2 as sensitive index of the danger of coal and gas prediction of coal seam 2# of Tongshun mine ,then K1 and S as auxiliary reference index.
