| Popis: | The Hrabuvka Quarry was one of the quarries on which the seismic effects were measured when performing large-scale blasting operations – bench blasting. These measurements were carried out as part of a university project to investigate further unfavourable seismic effects of blasting operations with respect to the type of ignition and explosives used. The aim of this article is to determine whether during the large-scale blasting operations from April to June 2019 vibration speed values were measured, which could have adverse effects on quarry structures and to propose a suitable solution to reduce these values, for example by changing the type of ignition from non-electric to electronic and by changing the ignition timing of individual charges. |
