<p>The main purpose of the work is to address a technological problem of separating the stone blocks from a massif by controlling the effect of destructive forces, realized through an even distribution of loads and stresses inside the massif by means of a specially designed wedge-shaped tool, determining the shape and dimensional parameters of the destructive tool, as well as the frequency and speed of load application. This study is destined to solve problems, that ultimately enables designing of a machinery for rock destruction, viz: a) a quantitative assessment of the effects of properties of destructed medium on indicators of the impact energy transfer process, determining of optimal parameters of the working bodies of impact machines, as well as establishing the area of rational application; b) evaluating the repeatability of the effects of time and dynamics on the effectiveness of the crushing impact; c) optimizing of parameters of the process of rock destruction and structural characteristics of machines on the basis of the theory of impact destruction. This will form the basis for designing of highly effective, reliable and efаicient machines as well as of those able to work effectively with rocks of different strengths.</p>
