Research objective is to review the history of the energy theory based on works under Professor Pershin G. D, DSc. Introduction. Modern technology of solid minerals machine mining is implemented using a rock cutting tool. The mechanical impact on the rock is carried out by various winning and heading machines, as well as borehole and well drilling equipment. The tool’s contacting with rock causes dulling and wearing out. The intensity of work tool dulling affects mining machines performance, power and energy consumption, which, in turn, decisively influences performance indicators of mining. It should be noted that work tool wearing out and dulling affect the consumption of drilling steel and hard alloys. It has been established that the mean specific consumption of drilling steel is about 200 g/m3 . Until now, researchers have evaluated rock abrasiveness experimentally through special laboratory and bench tests. Three main stages of sustainable development of the energy theory of natural stone diamond-abrasive destruction have been identified. Indicators and criteria for the diamond cutting tool performance have been established. It is logically substantiated that as a transition from macro-destruction criteria to the micro-level of diamond grain and sawn rock interaction, more accurate quantitative indicators of diamond destruction are realized. Methods of research. An integrated approach was used that includes the scientific analysis and generalization of previously published studies, analytical dependencies and system analysis. Scope of research. This energy theory makes it possible to implement a versatile approach that is supposed to be used when studying the performance of a diamond cutting tool and also allows the most complete and accurate assessment of a particular factor effect on the outcome of natural stone diamond-abrasive destruction. The research results make it possible to compile a unified universal classification of rock resistance to surface destruction by a diamond-abrasive tool when sawing natural stone.
