刘家梁矿5~#煤层瓦斯抽放技术研究与应用

Research and Practice of Gas Drainage Technology of 5~# Coal Seam in Liujialiang Mine

刘家梁煤矿在采掘过程中出现瓦斯涌出量增大、浓度超限等情况,必须采取瓦斯抽放技术防治瓦斯。通过对不同瓦斯抽放技术的分析,决定采用底抽巷施工对瓦斯进行预抽放。本文从巷道掘进和工作面回采期间两个方面的施工方案,介绍了瓦斯抽放技术的研究与应用,总结了取得的效果。

In the process of mining, there are gas emission and concentration exceeding the limit in the mining process of Liujialiang Coal Mine. Gas drainage technology must be adopted to prevent gas. Through the analysis of different gas drainage technologies, it is decided to use the bottom drainage tunnel construction to pre drainage the gas. This paper introduces the research and application of gas drainage technology from two aspects of roadway excavation and working face recovery, and summarizes the results achieved.
