Abstract
The technique of measuring the accelerations generated in the elements of the striker head - tool system is presented when it interacts with the rock mass. The measurements oscillograms and their analysis are shown. The quantitative aspects of the phenomenon are discussed, and an attempt is made to reveal the relationship between the quantitative parameters of impact pulses and fracture results.
