吉伦台—塘坝煤矿区侏罗系中统西山窑组主采煤层对比探讨

Comparative discussion on the main coal seams of the Jurassic system Xishanyao group in Jiluntai-Tangba coal mining area

吉伦台—塘坝煤矿区为内陆型沉积的煤系地层,煤层结构复杂,地层变相大。文章采用岩相旋回特征对比法、标志层对比法、煤层特征对比法、煤质特征对比法、地球物理测井对比法对内陆型含煤地层主采煤层进行了对比探讨。主要运用矿物岩石学及化学组分分析及岩相分析等方法,并逐条论述其优缺点,对内陆型沉积的侏罗系中统西山窑组含煤地层的划分及构造推断具有一定的指导意义。

Jiluntai-Tangba coal mining area is inland-type deposition coal series strata.The coal structure is complex,and the strata change is large.This paper comparatively discusses the main coal seams of inland-type coal-bearing strata with lithofacies cyclicial characteristics contrast method,mark layer contrast method,coal seam feature contrast method,coal quality feature contrast method and geophysical physical logging.This paper mainly uses mineral petrology,chemical composition analysis rock face analysis and other methods,and discusses their advantages and disadvantages one by one,which has certain guiding significance for the diversion and tectonic inference of the coal-bearing strata in inland-type deposition Jurassic system Xishantong group.
