| 中文摘要: |
| 黄河北矿区阳谷—茌平煤田与济宁、巨野煤田相似,属全掩盖式华北型石炭—二叠纪含煤岩系。因煤系地层沉积环境的变化和受聚煤期后构造运动的影响,煤层遭受了不同程度的沉缺、剥蚀、断缺等影响,整个煤田缺乏整体研究,含煤地层划分较为混乱。本次通过煤系地层沉积特征及聚煤变化规律的研究,采用煤岩层组合特征、标志层、层间距、测井曲线形态和地震物性特征等方法,对区内山西组、太原组的煤、岩层进行综合对比,进一步确定了主采煤层的赋存层位、形态及区内的构造格局。为该煤田总体煤炭资源储量估算、地质综合研究及煤田总体开发规划提供了依据。 |
| 英文摘要: |
| Yanggu-Chiping coalfield in the north mining area of the Yellow River is similar to the Jining and Juye coalfields and belongs to the north China type Carboniferous-permian coal-bearing series. Due to the change of sedimentary environment of coal measures strata and the influence of tectonic movement after coal accumulation period, coal seam has suffered different degrees of subsidence, denudation, fault and so on,the whole coal field lacks the whole research, the coal-bearing stratum division is more confused. Based on the study of the sedimentary characteristics of coal measures strata and the laws of coal accumulation, the methods of combination characteristics of coal and rock strata, marker strata, interval, logging curve shape and seismic physical characteristics are adopted, through comprehensive comparison of coal and rock layers of Shanxi Formation and Taiyuan Formation in the area, the occurrence position, shape and structural scheme of the main coal seam are further determined. It provides a basis for the estimation of the total coal reserves, the Comprehensive Study of geology and the overall development plan of the coal field. |
