The article introduces results of interrelations investigation of energy characteristics of roller-bit drilling and blasting
destruction of rocks. It is shown that the account of production wells drilling process parameters makes it possible to
simulate changes in strength characteristics of rocks in mine blocks and refine the parameters of blasthole charges of
explosives. The introduced results of interrelations investigation of roller-bit drilling and blasting destruction of rocks prove
that rocks properties refinement at drilling and blasting operations has high scientific and practical significance.

Key words: physical and mechanical properties of rocks; roller-bit drilling; drilling and blasting operations; blast; drilling and
blasting parameters.
