摘　　要：针对近距离煤层群1405首采工作面瓦斯涌出量大、瓦斯超限问题,以O形圈理论为依据,在1405 W型通风走向长壁对拉采煤工作面中,采用顶板高位钻孔瓦斯抽采技术,抽采采动影响范围内本煤层和邻近煤层卸压瓦斯。In order to solve a large amount of gas emission from contiguous seams and gas concentration exceeding limit in first-mining double working face on the strike 1405, roof highly-located holes gas drainage technology is chosen to drain relief-pressure gas from extracting seam and adjacent seams in mining influence area on the basis of O-ring theory.

关 键 词：近距离煤层群 顶板高位钻孔 卸压瓦斯
