Abstract:
The application of the designed blast patterns enables reduction in powder factor by 20–30%, decreases yield of oversize by 15–20%, lowers amplitudes of the stope floor and ground surface vibrations and reduces seismic energy from 106 to 104 J.

Keywords: rockburst hazard, seismicity, blast pattern, reduced powder factor, seismic energy
