Abstract

The approach of physical mesomechanics is applied to the problem of coal fracture. The coal is regarded as a natural composite with a hierarchical inner structure. Results of experimental investigation of fracture surface of different coal ranks are presented. Analysis of specimen surface fractal dimension revealed three scale levels of block-type inner structure of coals.
