矿井瓦斯抽采提浓研究

摘要

Through analyzing the influencing factors of drainaging effect,puts forward the “eccentric drilling”grouting tech-nique,and practices in Duanshi coal mine,investigates and contrasts its effect,and verifies its reasonableness,improves the gas concentration in the drainaging pipelines.%通过对影响瓦斯抽采效果的因素的分析，提出了偏心钻孔水泥注浆封孔工艺，并在端氏煤矿进行了实践，对其效果进行了长期考察对比，验证该工艺的合理性，提高了矿井瓦斯抽采浓度。
