| 摘 要： | 依据钻探资料对永陇矿区天堂勘查区含煤地层、可采煤层的分布与厚度变化进行分析,认为天堂勘查区含煤地层的赋存主要受三叠系基底形态的控制,基底的隆起与凹陷控制了含煤地层的厚度及分布范围,在凹陷区延安组沉积厚度大,煤层较厚,隆起区延安组沉积厚度小甚至缺失。

| Abstract: | Based on drilling data analyzed coal-bearing strata,mineable coal seam distribution and thickness variation in Tiantang exploration area,Yonglong mining area,considered that the hosting of coal-bearing strata is controlled by Triassic basement configuration.Coal-bearing strata thickness and distribution extent are controlled by basement uplift and depression,Sedimentary thickness of Yanan Formation is large in depression region with thicker coal seams,while thinner in uplift region even hiatus. |

| Keywords: | coal-bearing strata coal seam hosting uplift region depression region Tiantang exploration area |
