摘　　要：新集一矿151105综采工作面机巷沿空掘进期间,采空区瓦斯由煤(岩)体裂隙向掘进巷道溢出,回风流中瓦斯经常达到临界值,通过采取超前钻孔探放瓦斯,利用均压、喷浆封堵、双局扇等技术措施,有效地解决了隐患,实现安全掘进作业。During driving belt entry of 151105 fully mechanized coal face along goaf, the gas overflowed from goaf by coal（rock） toddy cranny, the gas concentration reached the critical value in air return flow, by adopting advanced drilling ex-ploration, used air pressure balancing, plugging with grouting, double local - fans and other technical measures, effectively solved the problems, to and achieved safe driving operation.
