七台河矿区属典型的低透气性薄煤层，随着煤矿井下开采深度的增加，用单一的通风方法已不能消除瓦斯威胁。本文结合实际探索了在掘进卸压区内进行钻孔抽采、采空区瓦斯埋管抽放及地面抽放等综合抽采的具体做法，并与传统方法进行了对比，效果明显。

Qitaihe mining area is typical in low permeability thin coal seam, with the increase of mining depth underground , the gas threats can not be eliminate by a single ventilation method. Te paper compares with the traditional methods by researching the there methods in gas drainage such as： gas drainage with pressure relief, gas drainage from gob , gas drainage on surface. And the effects are better than before.
