基于巷道“三带”瓦斯含量分布特征的合理封孔深度研究

Research on Reasonable Sealing Depth of Boreholes Along Seam based on the Gas Content Distribution Characteristics Along the "Three Zones" of Roadway

根据巷道“三带”应力分析特征,分析巷道周边瓦斯赋存规律,试验考察巷道“三带”瓦斯含量,分析得出煤层瓦斯含量分布规律、巷道“三带”范围及矿井顺层钻孔合理封孔深度。

According to stress zoning characteristics,this paper analyzed gas occurrence regularity along tunnel-surrounding, experimented and investigated the gas content along the "three zones"of roadway,obtained the gas content distribution characteristics,the range of the "three zones"and the reasonable sealing depth of boreholes along seam.
