New criterion for estimate of ground vibrations during blasting operations in quarries
The paper deals with a new criterion of evaluating the disintegration by blasting operations using cylindrical as well as concentrated charges in quarries and undergrounds. The results of our research show that for seismic safety determination of blasting, the maximum of concentrated charge blasting...

| Zusammenfassung: | The paper deals with a new criterion of evaluating the disintegration by blasting operations using cylindrical as well as concentrated charges in quarries and undergrounds. The results of our research show that for seismic safety determination of blasting, the maximum of concentrated charge blasting in one delay stage is not critical, but decisive is the explosion of the total mass of blasting material. KEYWORDS: blasting operations, seismic safety |
