Abstract

A calculated model of rock lump splitting off under impact of a wedge-like instrument is proposed, taking into account repetition factor and axis direction of impacts. It is substantiated that at a constant energy of single impact, the split offlayer width is possible to enlarge by delivering series of impacts.
