本文运用分形几何学理论探讨煤的条带结构特征，统计分析了大同侏罗纪部分煤的条带结构分维数，发现煤的条带结构具有很好的分形特征，可用分形维数表示煤条带结构的复杂程度。同时，将煤条带结构分形维数与煤相进行了综合研究，结果表明：煤条带结构分形维数与煤形成的泥炭沼泽相有着较好的对应关系，认为煤条带结构分形维数可作为煤相划分的参数之一。
In this paper, fractal geometry theory is used to explore the structural characteristics of coal strata. The fractal dimension of some coal in Datong Jurassic period is statistically analyzed. It is found that the coal strata structure has good fractal characteristics and the fractal dimension can be used to represent coal The complexity of the band structure. At the same time, the fractal dimension of coal strip structure and the coal phase are comprehensively studied. The results show that the fractal dimension of coal strip structure has a good correspondence with the peat swamp phase formed by coal, and the fractal dimension of coal strip structure Can be used as one of the parameters of the coal phase.
