Abstract
Experimental studies of the granulometric composition of rock mass obtained as a result of blasting and impact destruction confirmed good convergence of experimental data with the theoretical log-normal distribution law. It is proved that the logarithmic dispersion of the lognormal law of distribution of pieces of the fragmented rock massif is a structural invariant at the level of the statistical set of blocks and pieces. The model of destruction of polymineral rocks by explosion energy is proposed.
