摘　　要：介绍了国内外瓦斯与油型气灾害防治技术的研究现状。针对黄陵矿区煤油气共生的实际情况,采用掘前定向长钻孔区域预抽、掘进工作面边掘边抽、采前预抽、顶板走向高位裂隙抽放、上隅角抽放、采空区泄压抽放等综合措施,对矿井瓦斯进行了治理,并介绍了油型气灾害防治技术及方法。实践结果表明:采用措施后,黄陵矿一、二号矿井再没有发生过瓦斯与油型气的异常涌出情况,两矿井连续4年实现瓦斯零超限,防治效果良好。This paper described the research status of the prevention and control technologies for mine gas and oil-type gas disasters both at home and abroad. To counter to the actual situation of coal-oil-gas association in Huangling Coal Mining Area, comprehensive gas control measures were taken, including regional gas pre-drainage by directional long holes before driving, gas drainage in the heading face while driving, gas pre-drainage before mining, gas drainage by high-located fractures along the roof, gas drainage from the upper corner angle, pressure-released gas drainage from gob and so on, the prevention and control technologies and methods for oil-type gas disasters were also described. The practice results showed that after the measures were taken, the abnormal gas and oil-type gas emissions did not occur in No. 1 and 2 mines in Huangling Mining Area, gas overrun did not happen in four years, and better gas prevention and control effect was achieved.
