Under general geological study of exploratory development of coalbed gas and underground gasification of coal bed in eastern depression of liaohe basin , authors apply the basic principle of coal geology and the data of vitrinite reflectance and technical analysis of coal to ascertain that coal classification are dominantely the lignite , long - flame coal and gas coal of coal - bearing upper section of third member of shahejie formation , and then dissertate the variational regularity between coal rank and buried depth in vertical and otherness of vertical limit of coal rank in different coal - rich regions 摘要运用煤田地质学基本理论和煤的镜质组反射率值及工业分析等有关数据,确定了辽河盆地东部凹陷古近系沙三段含煤亚段的煤种主要为褐煤、长焰煤和气煤;进而阐述了该煤段垂向上煤级与埋深的变化规律性、不同赋煤区各煤级垂向界限的差异性。
