摘　　要：为解决铁新煤矿瓦斯涌出异常区域的瓦斯问题,系统分析了在采9号煤层瓦斯异常区域的断层构造、褶皱构造和水文地质条件,对9号煤层和其下邻近层10号煤层的瓦斯赋存分布规律进行研究,分析了9号煤层生产期间的瓦斯涌出量及瓦斯来源。通过分析发现,铁新煤矿9号煤层回采工作面涌出的瓦斯主要来源于下邻近层10号煤层,因此,有针对性地采取了现采空区插管抽采瓦斯和下邻近层穿层钻孔预抽瓦斯的综合瓦斯治理技术,该技术应用后取得了很好的瓦斯治理效果。In order to solve the gas problem in the abnormal gas emission area of Tiexin Coal Mine,the fault structure,fold structure and hydrogeological conditions in the abnormal gas emission area of No.9 coal seam were systematically analyzed.The gas occurrence and distribution law of No.9 coal seam and its adjacent No.10 coal seam were studied,and the gas emission amount and gas source during the production of No.9 coal seam were analyzed.Through the analysis,it is found that the gas emitted from the working face of No.9 coal seam in Tiexin Coal Mine mainly comes from the lower adjacent seam No.10 coal seam.Therefore,a comprehensive gas control technology was adopted in a targeted manner,which includes inserting pipes to extract gas from the goaf and pre extracting gas through boreholes in adjacent layers.After the application of this technology,good gas control results were achieved.
