发布时间：2018-09-14 15:24
【摘要】：针对固庄煤矿15707综放工作面回采期间遇褶曲带,又逢周期来压,上隅角、专用排瓦斯巷、回风巷瓦斯严重超限,致工作面停产,采用常规处理方法进行治理收效甚微。分析瓦斯超限的原因确定了两个治理方案,并比较了优缺点,采取以15707备采巷和专用排瓦斯巷施工抽放钻孔对上隅角瓦斯进行抽放。随着工作面的推进,未出现瓦斯超限,顺利通过褶曲带。
[Abstract]:In the face of 15707 fully mechanized caving face of Guzhuang coal mine, there is a fold zone during the mining, and every cycle pressure, upper corner angle, special gas drainage roadway, return air roadway gas seriously exceed the limit, the working face is shut down, and the conventional treatment method has little effect on the treatment. This paper analyzes the reasons of gas exceeding limit and determines two control schemes, and compares the advantages and disadvantages, and adopts the method of drainage borehole in the upper corner with 15707 ready mining roadway and special gas drainage roadway. With the advance of the working face, there is no gas overrun and passes smoothly through the fold zone.
