工作面卸压区瓦斯地面钻井抽采技术研究

Study on Gas Surface Drilling and Drainage Technology in Pressure-relief Area of Working Face

以山西晋煤集团岳城煤矿1303(下)综采工作面为例,探讨了地面采动井抽放治理采空区瓦斯技术,试验结果表明,利用地面采动井抽放可有效抑制采空区瓦斯向回风巷涌出,大幅降低回风巷瓦斯涌出量。

Taking Yuecheng Coal Mine 1303 fully mechanized mining face of Shanxi Jin Coal Group as an example,this paper discusses the gas drainage technology of ground mining well to control goaf gas. The test results show that the use of ground mining well drainage can effectively restrain the gas emission from goaf to return air roadway and greatly reduce the gas emission from return air roadway.
