摘　　要：针对新集二矿历次煤与瓦斯突出特征的考察研究,分析得出新集二矿煤与瓦斯突出对反映地应力和瓦斯压力的指标较为敏感。同时采用现场实测与实验室模拟相结合的分析方法对新集二矿防突预测指标的敏感性进行了系统的分析,并确定了各预测指标的临界值。结果表明,对于区域预测,瓦斯压力指标比瓦斯含量指标要敏感;对于局部预测,6#煤层和13-1#煤层的突出敏感性为S>K1>△h2,8#煤层的突出敏感性为K1>S>△h2。According to the investigation and study on the characteristics of previous coal and gas outburst,it analyzed and obtained that the coal and gas outburst was more sensitive to the indexes of ground stress and gas pressure in Xinji No.2 Coal Mine.The field measurement and laboratory simulation combined analysis methods were applied to systematic analysis on the sensitiveness of outburst prevention prediction indexes,and the critical values were determined.The results showed that： the index of gas pressure was more sensitive than that of gas content for regional prediction;for local prediction,the outburst sensitivity indexes of No.6 and No.13-1 coal seams were that S valueK1 value△h2 value,while K1 valueS value△h2 value in No.8 coal seam.
