采空区瓦斯抽放技术研究

Research on Gas Drainage Technology in Mined-out Area

采空区瓦斯是回采工作面瓦斯涌出主要来源之一,往往涌出量较大且稳定。文章分析了采空区瓦斯涌出的特征和规律,以及采空区瓦斯抽放的可行性,介绍了采空区的瓦斯抽放方法,提出了采空区瓦斯抽放方法的发展趋势。对于了解和认识采空区瓦斯抽放的重要性、涌出特征和抽放方法等具有现实意义。

One of the main source of gas emission in the working face comes from the mined-out area,and the emission quantity are often larger and stability.In the paper,the emission characteristics and laws are analyzed for the gas in mined-out area,and the feasibility of the gas drainage is also discussed.The gas drainage methods of the mined-out area are simply introduced,and then a method of gas drainage is put forward in the future.It has a certain practical application guide to understand the importance of gas drainage, the characteristics ot gas emission and the method ot gas drainage.
