为深入研究煤矿沉积地质环境,从基础岩芯描述着手,观察岩相特征,逐个钻孔寻找研究岩相标志,充分利用测井曲线提供的岩相信息,结合相邻钻孔同层位的岩相特征合理确定岩相。通过对岩相剖面和岩相古地理图分析,最终可确定河流体系砂体的形态和分布范围,很好地解释了1~#与2~#煤层间距在这一带加大的原因。
In order to further study the sedimentary geology environment in coal mines, starting from the description of basic cores, observing the lithofacies characteristics, looking for and studying lithofacies markers one by one, making full use of lithofacies information provided by well logs, Phase characteristics of a reasonable determination of lithofacies. Through the analysis of lithofacies section and lithofacies palaeogeography, the shape and distribution range of the sand body of the river system can be finally determined, and the reasons for the increase of the interval between 1 # and 2 # coal seam in this zone are well explained.
