摘　　要：针对龙滩矿井综采工作面W型通风系统,易造成回采工作面中隅角瓦斯积聚与超限问题,以龙滩矿井3112南回采工作面为工程研究背景,提出采取主动抽放采空区瓦斯,实施高抽巷瓦斯治理技术,实现了中隅角与回风巷瓦斯不超限,保证了矿井安全生产。In view of W-type ventilation system in Longtan coal mine fully mechanized working face, it is easy to cause gas accumulation and overrun in the middle corner of mining face. Taking 3112 south mining face of Longtan mine as the engineering research background, proposes to take active gas drainage in goaf and implement gas control technology of high drainage roadway, so as to realize the gas limit of middle corner and return air roadway, and ensure the safety production of mine.
