摘要
分析了低透气性煤层的主要特征,在此基础上研究了适用于永贵能源典型低透气性煤层的瓦斯治理思路与方法。针对不同的低透气性煤层赋存条件,实施了开采保护层、施工底(顶)板抽放巷并采用水力化措施、利用顺层钻孔抽采煤巷瓦斯等防突技术,取得了较好的效果。
The main characteristics of low permeability coal seam are analyzed.on the basis,Yonggui Energy and Resows Development Co.,Ltd.,find a suitable gas control methods for low permeability coal seam.According to the different low permeability coal seam,a mining protection layer,construction of the bottom(top) plate drainage lane and the hydraulic measures are implemented,the bedding of boreholes in coal roadway gas and other measures,and achieved good results.
