摘　　要：为了提高预抽煤巷条带瓦斯区域防突措施效果检验效率,保证安全生产,提出用钻屑瓦斯解吸指标Q3、Q20和瓦斯含量逐级对区域防突措施进行效果检验的方法,通过实验研究了各解吸指标与瓦斯压力和瓦斯含量之间的关系,并在平煤股份八矿区已15-13330机巷进行了现场试验,应用效果良好。In order to improve the verification efficiency of the outburst prevention measures for strip mining gas region of the gas pre-drained seam gateway and to ensure the safety production,the paper provided the method of the drilling cuttings gas desorption index Q3 and Q20 and the gas content applied to the effect verification of the outburst prevention measures steadily.With the experiments,the relationship between the each desorption index and gas pressure and gas content was studied.A site trial was conducted in Yi 15-13330 conveyor gateway of No.8 Mine of Pingdingshan Coal Mining Group with good effects.
