摘要
平朔露天矿的露采煤层，即１１＃和９＃煤层是上石炭统太原组Ⅱ－Ⅲ层段扇三角洲一泻湖及扇三角洲一潮坪环境的产物。厚４ｍ的１１＃煤层形成于扇三角洲一潮坪环境中；厚１５ｍ的９＃煤层形成于扇三角洲平原、扇三角洲前缘（北西部）以及覆水较深的泻湖（中南部）环境中。
The 11 # and 9 # coals, exposed and mined at Pingsuo open pit mine, occur in Ⅱ Ⅲ intervals of the Taiyuan Formation, Upper Carboniferous. They were accumulated in environment of fan delta lagoon and fan delta tidal flat. The 4m thick 11 # coal was formed in an environment of fan delta tidal flat and the 15m thick 9 # coal in an environment of fan deltaic plain, fan delta front and lagoon covering with deep water.
