Abstract
The article considers the problem of size distribution of grain-size composition of the blasted rock mass, rock fragments blasted rock mass and rock blockiness. The logarithmic-normal distribution law is laid down for all blasted granite mass products. It was proved, that logarithmic variance of logarithmic normal distribution law of the fractured rock mass fragments’ distribution is a structural invariant on the level of statistical universe of the block and fragments.
