单一复合煤层综采工作面上隅角瓦斯治理技术研究

摘要

本文针对单一复合煤层上分层开采过程中出现瓦斯涌出量增加、回采工作面瓦斯浓度超限的实际问题，对27012工作面快速回采中采取的各种处理上隅角瓦斯积聚的方法进行了论述与分析，同时对李子垭煤矿今后生产过程中的上隅角瓦斯管理工作提出了相应的治理技术及措施。%Aiming at the real problems of the amount of gas emission increasing and gas concentration overrunning in mining face appeared in the mining process of single-composite coal seam, this paper discusses and analyzes the methods of dealing with the gas concentration in the upper corner of 27012 mining face, and proposes the corresponding control technology and measures for the gas management in the upper corner of the Liziya Coal Mine in the future production process.
