摘要
分析现行矿用合成树脂封孔法效果不良的原因,提出了囊袋式注浆封孔法,并在东曲矿12509工作面的皮带顺槽进行了试验。结果表明,利用囊袋式注浆封孔法与矿用合成树脂封孔方法相比瓦斯抽采浓度有明显的提高,封孔效果明显。
This paper analyzes the causes of the current mine synthetic resin sealing method of adverse effect, the bag type grout sealing method, the belt in 12509 working face of Dongqu mine roadway were studied. The results show that the use of bag type grout sealing method than mine synthetic resin sealing method in gas drainage concentration improved sealing effect is obvious.
