本文运用分形理论，对新汶煤田红层的微孔隙发育规律进行了研究，结果表明，红层的孔隙分布具有自相似性，分维值是真实地反映孔隙特征的一个综合指标。
In this paper, fractal theory is used to study the micropore development of red beds in Xinwen coalfield. The results show that the pore distribution of red beds is self-similar and the fractal dimension is a comprehensive index that can truly reflect the pore characteristics.
