The article describes the results of the study of the process of destruction of rocks by contact. The indentation of the indenter into the well wall was considered. A body with a cylindrical surface was used as an indenter. The authors of the article applied the theory of contact interaction of G. Hertz. The strength theory was used as a criterion for destruction. K. Mohr. The dependence obtained by the authors was tested using mathematical modeling. The results of mathematical modeling have confirmed the possibility of practical application of the resulting relationship.
