吉伦台-塘坝矿区为内陆型沉积的煤系地层,煤层结构复杂,地层变相大,采用标志层对比法、岩相-旋回特征对比法、煤层特征对比法(煤厚及结焦性)、地球物理测井对比法及综合分析对比对内陆型含煤地层主采煤层对比进行了探讨,主要侧重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下统八道湾组含煤地层的划分及构造推断具有一定的指导意义。
The Qiluntai-Tangba mining area is an inland-type coal-bearing strata. The structure of the coal seam is complicated and the strata of the strata are large in disguise. By means of the comparison of signage layer, contrasting lithofacies-cycle feature, coal seam feature contrasting method Geophysical Well Logging Comparisons and Comprehensive Analysis Comparisons The main coal seams in the inland coal-bearing strata are discussed in this paper, which mainly focus on methods of mineralogy, chemical composition analysis and lithofacies analysis, and discuss their advantages and disadvantages one by one. It is of guiding significance to the division and tectonic inference of the coal-bearing strata of the inland sedimentary Jurassic Badaowan Formation.
