【 摘 要 】

According to the Xuecun mine field measured data, the gas outburst prediction index is analysed by the qualitative. It is the use of gray relational analysis and the "three rate" calculated quantitatively predict the sensitive indicators of Xuecun mine. The results show that the results of qualitative analysis and quantitative are agreement. It initially came to the prominence predictor of Δh2, the sensitivity of which is better. It improves the reliability of sensitivity index for 2# coal working face of xuecun mine.
