外错型高抽巷瓦斯抽采技术研究及实践

On the Research and Practice of Gas Extraction Technology in Unofficial Type High Level Suction Roadway

瓦斯灾害一直是影响矿井安全高效生产的主要问题之一,采空区瓦斯治理是矿井瓦斯治理的主要难点,李雅庄矿尝试采用高抽巷进行瓦斯抽采解决这一问题。以李雅庄矿为例对外错型高抽巷瓦斯抽采技术进行分析,以提升技术应用水平。

Gas disaster has been one of the major problems affecting the safe and efficient production, gas governance in goaf is the main difficulty in mine gas control, Liyazhuang Coal Mine tried to adopt gas extraction technology in high level suction roadway to solve this problem. This paper analyzed gas extraction technology in unofficial type high level suction roadway by taking Liyazhuang Coal Mine as an example to enhance the level of technology application.
