摘要
振兴矿在掘进期间采取"打钻、先抽、后掘"作为瓦斯治理的重要手段,严格执行掘进期间回风道每隔25m、机道每隔40m施工抽放钻孔的刚性规定,合理安排规划瓦斯治理工程,认真分析和预测各块段瓦斯涌出规律及变化情况。
The main method of ＂ drilling, pre-- drainage-- gas control and driving＂ is applied in gas control during driving in Zhenxing Colliery, which is in strict accordance with the rigid rules of gas drainage in air return way every 25 meters and in machine runway every 40 meters with rational planning of gas control engineering by a- nalysis and prediction of gas emission law and changes.
