摘　　要：基于某隧道6#煤层进行测试,采用瓦斯压力、瓦斯含量及钻屑瓦斯解吸指标K1值,预测煤层突出危险性,通过多项指标相互验证,提高了指标的准确度和可靠性。通过理论和实践表明,瓦斯含量辅助钻屑瓦斯解吸指标可作为隧道快速揭煤突出危险性预测的指标。Based on the test of the No. 6 coal seam of a tunnel, using gas pressure, gas content and gas desorption index K1 value to predict coal seam outburst risk, the accuracy and reliability of the index are improved by using a number of indicators. Through theory and practice shows that, gas content and gas desorption index of drill cuttings can be used as the index of the quick coal outburst risk prediction of tunnel.
