煤条带结构的分形特征及地质意义初探

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。

The fractal characteristics and geological significance of the banded structures of some Jurassic coals in Datong coal basin

The fractal geometry theory and methods are used to study the banded structures of some Jurassic coals in Datong coal basin. It is concluded that the banded structures in coals are self similarity, and that there exist correlations either between fractal dimensions and the complexity of the banded structures or between the fractal dimensions of the banded structures and the facies of coals. The fractal dimension may be used as one of the parameters to identify the complexity of the banded structure and the facies of coals.
