Аннотация: The initial stage of an increase in axial compression is characterized by a decrease in the total porosity and its two components (intergranular and fractured), but a further increase in axial compression showed differences for samples depending on the value of the fractured porosity. Thus, in a sample with a small value of fracture porosity, the preparation of fracture was accompanied mainly by a decrease in total and intergranular porosity and an increase in fracture porosity, i.e., an increase in microcracks. The preparation of the fracture of the sample, which initially contained an increased fracture porosity, is characterized by an increase in the total and intergranular porosity and a decrease in the fracture porosity. The method of assessing the fracture porosity of the studied samples revealed differences in the processes of preparing their destruction.
