A physical model is created to describe stage-by-stage fracture of rock mass by deep-hole blasting. The analytical dependences are presented for main parameters of massive blasting. The zones of intense and passive crushing are identified in a blasted bench. The formulas are obtained to calculate volumes of different size particles in these zones. The automated determination procedure of particle size distribution is proposed. The program in Microsoft Visual Studio 2017 environment allows the automated analysis of blasthole pattern in a bench and particle size distribution in broken rock mass depending on initial data.
