卸压钻孔抽放瓦斯在采煤工作面的应用

摘要

The gas pressure in a fully mechanized face is usually released by mining activities.The seam gas drainage from boreholes while mining reduced gas emission in the face and increased coal output, this provided a new way to control gas emission in coal seams with low permeability.%通过对综采工作面受采动影响产生瓦斯卸压作用，利用钻孔进行本煤层瓦斯边采边抽，减少了工作面瓦斯涌出量，为治理低透气性煤层工作面瓦斯涌出探索了新途径。
