不规则综采工作面瓦斯综合治理方案研究

Gas Control Measures of Irregular Mechanized Working Face

由于受多种因素的影响,煤矿综采工作面多呈现不规则形状。以口孜东矿111304工作面为例,采用高位钻孔、顶板倾向钻孔、高抽巷、煤层顺层钻孔和上隅角埋管抽放等多种相结合的方法对该工作面瓦斯进行抽放,取得了良好效果,保证了工作面的安全回采,为其他同类工作面瓦斯抽放提供了参考依据。

Because of the effect of many factors, most of fully mechanized working faces in coal mines are in irregular shape. The article takes 111304 working face of Kouzidong coal mine as an example. It has used the combined method of the high drilling, roof tendency drilling, high drainage roadway,drilling holes along coal seam, buried tube drainage in upper corner and other methods to drainage gas on the working face and obtained the good effect. These measures have make the mining working face safe and provided basic for other similar coal face.
