摘要
通过对第四系沉积物孔隙度的分析及对研究区岩矿特征、密度资料的研究，推算出不同岩性岩石厚度的压缩率和压实比。根据压实比换算出过去一定埋深范围内的原始沉积厚度，从而作出原始沉积的岩相古地理剖面图。这种剖面图可以直观地解决复杂结构的煤层对比问题，直观地分析地层沉积演化过程。
Through analysis on porosity of the Quaternary deposits and research on properties of minerals and rocks,and the data of density,the compression ratio and consolidation ratio of different deposited rocks in target area can be calculted.According to the consolidation ratio,the original thickness of deposits at certain depth can be calculated,too,so that it is possible to delineate the lithofacies—paleogeographic profile of original deposits.This kind of profile is useful for correlation of complicated coal seams and analysis on sedimentary evolution.
