Development features and fractal research of fault structure of No.5 coal seam in Chenghe-Second coal mine

摘要

Based on the collected geological exploration and underground mining data, this thesis has analyzed the development feature of faults of No.5 coal seam in Chenghe-Second coal mine and obtained fractal law of fault structure by fractal statistics. The result shows that the faults have a good self-similarity on the plane distribution and obvious fractal characteristics and that the larger the fractal dimension, the higher the complex degree of fault structures.
