Sažetak
Aim of the research was to determine maximum explosive quantity that will not consideraby influence the requested safety factor of the existing rock slope above the quarry plant. For that purpose it was crucial to determine the allowable explosive quantity considering seismic waves excited from blasting activity. The first phase of analysis determined the geological condition and geotechnical parameters of the potential failure zone, as well as determining the seismic coefficient that would cause the rock slope to become conditionally stabile. Slope stability was simulated using the computer software RocScience Slide 5.0 for the limit safety factor Fs=1.0, which resulted in an allowable ground particle horizontal acceleration value. With the calculated seismic coefficient and the predominant frequency, allowable explosive quantities were determined. Geological condition and geotechnical parameters of the potential failure zone were described with the use of GSI classification.
