Abstract

The results of regressive modeling the volume of
crystalline rock broke down in its experimental sample with drilling tool indenters by experimental
bursts are cited. It is displayed that the models represent regularities of its change due to the influence
of rock structure strength, the impact energy and indenters’ location. The theoretical interpretation of
regularities in terms of rock’s elastic-brittle properties and quasi-resonant phenomenon of the destruction of its walls formed between the indenters is
given. Practical conclusions and recommendations
are adduced.
