摘　　要：五轮山煤矿地处贵州山地,地质条件复杂,矿井属于煤与瓦斯突出矿井,煤层瓦斯不易解析。针对五轮山煤矿的特殊情况,首采工作面采用本煤层预抽瓦斯、采空区埋管抽放、高位抽放巷抽放瓦斯及上邻近层卸压抽放瓦斯,较好地解决了该工作面瓦斯超限问题,为正常生产创造了有利的条件,探索出了适合山地复杂条件的五轮山煤矿瓦斯综合治理技术。Wulunshan Coal Mine is located in Guizhou, which has many mountain and complex geological conditions. The mine belongs to a mine with coal and gas outburst, and the coal seam gas is not easy to resolve. For the special ease of the coal mine, the first mining face uses the predrainaging gas, goal buried pipe drainage, the high alley gas drainage and upper adjacent pressure relief gas drainage. It solves the face gas gauge problem well to create favorable conditions for the normal production and explores the gas control technology applied in Wulunshan coal mine in which the mountains have complex conditions.
