摘　　要：上庄煤业3103工作面所采煤层3号-3、3号-1和3号-2瓦斯含量都比较高,且距邻近层较近,瓦斯治理难度较大。根据附近工作面回采经验和现场资料分析,合理科学制定对3103工作面瓦斯综合治理技术方案,采用本煤层瓦斯抽放、邻近层瓦斯高位抽放、强制放顶等多种技术手段相结合,确保3103工作面安全高效生产。实践证明对煤层赋存情况复杂、瓦斯含量高工作面,采用瓦斯综合治理技术是行之有效的。No.3-3,No.3-1,and No.3-2 coal seams in the 3103 working face of Shangzhuang Coal Industry with high gas content and close to adjacent layers,making gas management difficult,based on the mining experience at the nearby working face and the analysis of the site data,a comprehensive and reasonable technical plan for the gas treatment of the 3103 working face was formulated scientifically.The combination of various technical means such as gas drainage in the coal seam,high-level gas drainage in the adjacent layer,and forced roofing ensured the safe and efficient mining of 3103 working face.The practice proved that it was effective to adopt the comprehensive gas management technology to the coal seam with complicated conditions and high gas content.
