摘要
利用钻孔抽采煤体瓦斯,降低回采工作面生产过程中的瓦斯浓度是确保矿井安全生产的重要手段,通过对影响抽采系统瓦斯浓度的因素进行分析,摸索出提高瓦斯抽采浓度的成套技术,可有效提高矿井抽采率,避免瓦斯事故发生。
By using the borehole coal gas,reducing gas concentration in working face in the process of production is an important means to ensure the safety in production of coal mine,through analysis of factors affecting extraction system of gas concentration,find complete technology improve the concentration of gas extraction,can effectively improve the mine drainage rate,avoid gas accident.
