摘要
通过对采空区顶板冒落状态分析及钻孔参数的试验研究,总结出适合主焦矿区的瓦斯抽放技术,提高了矿井的瓦斯抽放率,从根本上消除了上隅角瓦斯超限的现象。
In order to improve gas drainage rate in this main coking coal mine,highly-located drilling field is implemented in this mine based upon the gob roof and gas migration laws of this mine.This paper mainly gives an account about the utilization and practice of highly-located drilling field in this mine.Through analyzing the gob roof caving state and borehole parameters,gas drainage technology suited to this main coking coal mining area is developed,which improves the mine gas drainage efficiency and eliminates the phenomenon of excessive gas accumulation around the upper corners of the face.
