| 摘 要： | 针对回采工作面采空区瓦斯涌出量大，严重制约工作面安全高效生产的不利影响，通过研究分析回风流瓦斯涌出来源，确定利用高位抽放巷抽采采空区上覆围岩裂隙带瓦斯，改变了采空区瓦斯运移路径，有效控制了回风流瓦斯。并对抽采瓦斯利用，减少了“温室气体”排放，变废为宝，取得了良好的效果。

| Abstract: | In allusion to the large amount of gas emission in goaf，it seriously restricted the adverse effect of safe and efficient production in the working face.Through the analysis of the return air gas emission source，determined by high drainage roadway gob gas drainage of fracture zone on the overlying rock，to change goaf gas migration path，to control of the return air gas effectively.In addition，the use of gas drainage has reduced the emission of greenhouse gases and transformed waste into treasure，which has achieved good results. |
