摘要
通过对沙巴台煤矿17#煤层瓦斯涌出规律进行分析,确定矿井瓦斯抽采方法为本煤层预抽、边采边抽、边掘边抽、采空区抽采相结合的综合瓦斯抽采体系,强化抽采效果,保障矿井安全高效生产。
By analyzing the gas emission law of 17^#coal seam in Shabatai Coal Mine,the mine gas extraction method is determined to be a integrated gas extraction system of pre-drainage in the coal seam,mining with extraction,excavation with extraction,and the combination of extraction and mining in Gob,which can strengthen the extraction effect and ensure the safe and efficient production of the mine.
