【摘要】 基于煤炭资源调查评价成果,对研究区测水煤系沉积和展布特征等方面进行研究,总结出研究区测水煤系存在5种聚煤类型;两组不同活动强度古构造的综合作用,影响了煤系厚度及富煤带的展布方向;海进障壁沙坝的侵蚀性是研究区西北部薄系无煤型产生的原因。更多还原

【Abstract】 Based on the results of coal resources survey and evaluation, the paper studies the sedimentation and distribution characteristics of measuring water coal system, and concludes that there are 5 types of coal accumulation in the study area. The combined effects of two groups of different activity intensity paleo-structures affect the thickness of coal seams and the direction of the distribution of rich coal belts. The erosion of the transgression sand barriers is the cause of the thin coal-free type in the northwestern part of the study area.更多还原
