Abstract. Basic methodological provisions were drawn out for experimental studies of the stressed rock resistibility to mechanical breaking. The findings are necessary for improving existing and designing new rock cutting tool, elaborating parameters for the rock breaking modes, and specifying fields for rational usage of different types of the rock-breaking tools in concrete mining and technical conditions. The article presented devices for studying stressed rock resistibility to mechanical breaking designed by the IGTM, NASU, and an improved strengthmeter BP-18 designed by the VNIMI. Results of practical studies of the stressed rock resistibility to mechanical breaking are also demonstrated. A significant volume of experimental materials referred to specifying local strength is analyzed .

Keywords: rock, resistance to destruction, contact strength, slaughter, installation for researches resilience intense rocks mechanical failure, indenter.
