ABSTRACT
Experimental studies on destruction of blast models of charges with different crosscut shape are conducted. The processes of the stress field formation in rock mass in the blast explosive charges of different shapes with using mathematical modelling and finite element method is reviewed. The change of distribution of values around geotechnical parameters of the charge is analysed.
