摘　　要：瓦斯解吸指标不仅能够反映煤层瓦斯压力的大小和瓦斯放散初速度的快慢,而且能够反映钻屑初始解吸量的特征。主要探讨了钻屑瓦斯解吸指标Q3、Q20/Q30在不同瓦斯压力下的解吸特征,并对掘进工作面区域防突措施效果检验指标及临界值进行了分析。The gas desorption indicators can not only reflect the magnitude of gas pressure in coal seam and the speed of initial methane releasing rate, but also reflect the initial desorption characteristics of the cuttings. This paper discusses the desorption characteristics of index of drill cuttings absorption and release including Q3, Q20/Q30under different pressures, and finally analyzes effect test indicators and critical value of regional outburst prevention measures in heading face.
