摘要
因二塘向斜煤层较多,且大湾煤矿位于二塘向斜的两翼,所以基于大湾煤矿储量核实成果,对大湾煤矿的地质特征、含煤地层、煤层特征进行分析,采用标志层、煤层间距、测井曲线对比法对大湾煤矿煤层进行综合对比,为构造复杂、煤层形态及厚度不稳定的深部煤层划分及储量估算提供了地质依据.
Abstract
There are many coal seams in the Ertang syncline,and the Dawan Coal Mine is located on both wings of the Ertang syn-cline.Based on the verification results of the reserves of Dawan Coal Mine,an analysis was conducted on the geological character-istics,coal bearing strata,and coal seam characteristics of Dawan Coal Mine.A comprehensive comparison was conducted on the coal seams of Dawan Coal Mine using marker layers,coal seam spacing,and logging curves,providing geological basis for the classification and reserve estimation of deep coal seams with com-plex structures,unstable coal seam morphology and thickness.
