This paper proposes a model for determining the characteristics of the evolution of the field of microcracks in a loaded rock sample by electromagnetic radiation signals. Calculations were made, whose results were summarized in the form of space-time tables. Factors determining changes in the hierarchy of microcracks were established. The adequacy of the model was verified using the Zhurkov concentration criterion. Areas of scale invariance were revealed on graphs of the concentration of microcracks versus their size constructed on the logarithmic coordinates.
