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。
針對固莊煤礦15707綜放工作麵迴採期間遇褶麯帶，又逢週期來壓，上隅角、專用排瓦斯巷、迴風巷瓦斯嚴重超限，緻工作麵停產，採用常規處理方法進行治理收效甚微。分析瓦斯超限的原因確定瞭兩箇治理方案，併比較瞭優缺點，採取以15707備採巷和專用排瓦斯巷施工抽放鑽孔對上隅角瓦斯進行抽放。隨著工作麵的推進，未齣現瓦斯超限，順利通過褶麯帶。

The normal method had a poor effect on managing gas overrun in the return cor-ner,the special gas drainage gateway and the return roadway,resulting in the suspension of work face,when the 15707 top coal caving face encountered the fold structure and the periodic weigh-ting in Guzhuang Coal Mine. The two managing schemes were proposed by analyzing the causes of gas overrun. By comparing the advantages and disadvantages of the two schemes,the gas drainage in the return corner was implemented by drilling holes in the 15707 intake and the spe-cial gas drainage roadway. With the advancing of working face,the gas overrun in the return cor-ner had not happened and the working face had smoothly passed the fold structure zone.
