摘要
针对余吾煤业公司煤层透气性低赋存条件及放顶煤开采技术条件,提出地面钻井抽采采空区卸压瓦斯技术,并开展工程实践。
In view of the occurrence condition of low coal seam permeability and technical conditions of top coal caving mining of Yuwu Coal Industry Company, ground drilling drainage technology for pressure relief gas in goaf was proposed, and engineering practice was conducted.
