摘　　要：针对近距离煤层群下开采保护层时,瓦斯易从邻近层涌入回采工作面的问题,在试验煤矿采用了岩石截流钻孔抽放瓦斯技术,通过效果考察并将其与邻近层钻孔抽放瓦斯技术进行对比,结果表明:岩石截流钻孔抽放瓦斯技术能有效将上邻近层涌向工作面的部分瓦斯进行拦截,达到了防止工作面回采过程中瓦斯超限的目的。To counter the problem that gas may easily emit into the working face from the adjacent seam in the extraction process of the protective seam of the short-interval coal seam group,gas drainage technology by rock intercepting boreholes was used in the test mine,and comparison was made on the drainage effect with the drainage technology by boreholes in the adjacent seam.The results showed that the gas drainage technology by rock intercepting boreholes can effectively intercept a portion of gas that may emit into the working face from the upper adjacent seam and achieve the goal of preventing gas overrun in the working face.
