摘　　要：以岳城矿厚煤层分层开采为实例,由于分层开采的煤层瓦斯涌出的差异性,应针对性采用不同的瓦斯治理技术;上分层拟采用地面采动井、顶板走向长钻孔及回风隅角抽排的综合瓦斯治理技术;下分层开采时,针对瓦斯涌出量小的特点,拟采用回风隅角埋管抽排的瓦斯治理技术;采用“一面一策”的科学瓦斯综合治理措施后,能确保工作面安全高效生产;也可为其他类似矿井提供经验借鉴。Aiming at the difference of gas emission in slicing mining coal seams in Yuecheng Colliery,the author proposes the different gas control measures,in which comprehensive gas control technology with surface mining shaft,roof long-strike borehole and drainage in return airway corner is applied in upward slicing,and drainage with buried pipe in return airway corner in downward slicing,which can ensure the safety and efficient production and provide a reference for other similar mines.
