摘　　要：为探究突出煤层煤巷上下帮卸压消突规律,采用钻屑解吸指标法现场实测了706顺槽上下帮30 m范围内钻屑瓦斯解吸指标K1值、钻屑量S值,采用DGC瓦斯含量测试仪测试了706顺槽上下帮30 m范围内残余瓦斯含量W,并分析了3个突出表征参数沿着孔深的变化规律,为邻近工作面制定合理有效的防突措施提供依据,以期为类似条件矿井提供借鉴。In order to explore the law of pressure relief and outburst elimination on the upper and lower side of coal roadway in outburst coal seam, the drilling cuttings desorption index method was used to measure the drilling cuttings gas desorption index K1 value and drilling cuttings amount S value within 30 m of the upper and lower sides of the 706 groove, DGC gas content tester was used to test the residual gas content W within 30 m of the upper and lower sides of the 706 groove, and the variation rules of three outburst characterization parameters along the hole depth were analyzed, providing a basis for the development of reasonable and effective outburst prevention measures in the adjacent working faces. It is expected to provide reference for mines with similar conditions.
