摘　　要：针对陶二煤矿2214工作面瓦斯赋存特征、煤层赋存状态及巷道布置方式,采用顺层钻孔预抽回采区域煤层瓦斯、高位钻场顶板走向钻孔抽采邻近层卸压瓦斯、采空区埋管抽放、沿空留巷Y型通风相结合的瓦斯综合治理技术,并以精细化管理为保障,区域措施效果检验和区域验证指标均小于临界值,回采期间工作面上隅角瓦斯浓度控制在0.45%以下,回风瓦斯浓度控制在0.35%以下,杜绝了瓦斯超限事故,保证了矿井的安全高效生产。Aiming at gas occurrence characteristics, coal seam occurrence condition and roadway layout of 2214 work face at Taoer Mine, the comprehensive measures of gas pre extraction from coal seam, high level borehole extracting release from adjacent layer, gas drainage from tubes buried in gob, gob-side entry retaining and Y-shaped ventilation were adopted, and specified management was utilized as guarantee. Regional measures effect test and verification were less than the critical value. The concentration of gas of upper corner was under 0.45%, and the concentration of gas of return air was under 0. 35%. Gas overrun accident was eliminated and safety and efficient mining production was ensured.
