Abstract
Formulas and schemes are presented to determine lengths of charges and their inert gaps. The calculations are based on the theory of superposition of seismic blasting waves in a rock mass. The proposed procedure enables calculating parameters of distributed charges under any ground and geotechnical blasting conditions ensuring high-grade fragmentation, elimination of flyrock and reduction in drilling operations.
