Abstract

Miniranje je tehnika eksploatacije čvrstih mineralnih sirovina, iskopa u građevinarstvu te primjene eksploziva za različite ostale tehničke namjene. Raspoloživa energija eksploziva vrlo brzim kemijskim procesom transformira se u energiju stlačenih produkata eksplozije koji u ekspanziji obavljaju mehanički rad nad okolinom, odnosno drobe stijenu u oblik pogodan za preradu i upotrebu. Prilikom djelovanja eksploziva u minskom polju, na okolinu se javlja i neželjeni potresni odnosno seizmički utjecaj. Analiza utjecaja miniranja na lokaciji kamenoloma vapnenca i dolomita Špica je provedena u skladu s primijenjenim rješenjima miniranja. Pri tome su izdvojeni značajni utjecajni parametri te su definirani postupci za smanjenje brzina oscilacija, odnosno vibracija, kao mjere intenziteta i potencijalne štetnosti seizmičkog utjecaja miniranja.

Abstract (english)

Blasting is a technique of exploitation of solid mineral raw materials, excavation in construction and application of explosives for various other technical purposes. The available energy of the explosive is transformed by a very fast chemical process into the energy of the compressed explosion products, which in the expansion perform mechanical work on the environment, that is, crush the rock into a form suitable for processing and use. During the action of explosives in a minefield, an unwanted shaking or seismic impact occurs on the environment. The analysis of the impact of blasting at the location of the Špica limestone and dolomite quarry was carried out in accordance with the applied blasting solutions. At the same time, significant influential parameters were identified and procedures were defined for reducing the speed of oscillations, that is, vibrations, as a measure of the intensity and potential damage of the seismic impact of blasting.
