| 摘 要： | 在石炭-二叠纪，元氏地区随地壳脉状均衡沉降，海水频繁侵入。在二叠纪早期仍有海水侵扰，滨海环境在区内多次重复出现，发生多次聚煤作用，共形成煤层8～18层，可采煤层6层，其中稳定可采煤层2层，煤层总厚度约10m。由于元氏地区邻近石家庄-卫宁构造带，在石炭二叠纪聚煤期间具有相对活动的特征，下坳则覆水偏深，上隆则堆积补偿不足，均不利于泥岩沼泽之生成，致使此区聚煤程度明显逊于南、北两侧矿区。

| Abstract: | During Permo-Carboniferous period, along with earth crust pulsating even subsidence, sea water transgressed frequently. In early Permian still had sea water transgression, littoral environment multiply repeated in the area, thus multiple coal accumulation have happened, 8-18 coal seams formed, mineable coal seams 6, in which 2 stably mineable, coal seam total thickness about 10m. Owing to the Yuanshi area is adjacent to the Shijiazhuang-Weining tectonic belt, during the coal accumulation period in Permo- Carboniferous had characteristics of vis-a-vis activities, the downwarping inclined to deep water covering, upwarping inclined to insufficient cumulative compensation all went against the forming of peat bog, thus caused the area coal accumulation extent is obviously inferior to mining areas both in north and south. |
