【摘要】：針對固莊煤礦15707綜放工作面回采期間遇褶曲帶,又逢周期來壓,上隅角、專用排瓦斯巷、回風巷瓦斯嚴重超限,致工作面停產(chǎn),采用常規(guī)處理方法進行治理收效甚微。分析瓦斯超限的原因確定了兩個治理方案,并比較了優(yōu)缺點,采取以15707備采巷和專用排瓦斯巷施工抽放鉆孔對上隅角瓦斯進行抽放。隨著工作面的推進,未出現(xiàn)瓦斯超限,順利通過褶曲帶。
[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.
