摘要
以保德煤矿81304综放工作面日常瓦斯浓度测定数据为基础,结合工作面煤层赋存特征,找出了上隅角瓦斯超限的根源,并有针对性的提出了均压和采空区埋管抽放的综合治理措施,彻底解决了工作面上隅角瓦斯超限的问题。
Based on daily gas concentrations measured data in Baode coal mine 81304 fully mechanized caving face, combined with coal seam occurrence characteristics in working face, this paper found the root of gas overrun in the upper corner, and proposed directly comprehensive control measures of balancing pressure and gas drainage by buried pipe in gob, which completely solved the problem of gas gauge in the upper corner of working surface.
