Abstract

Miniranje je suvremeni postupak za razaranje i drobljenje stijena, materijala i objekata energijom eksploziva. Djelovanje detoniranog eksplozivnog naboja u minskoj bušotini uzrokuje naprezanja koja dovode do frakturiranja i i drobljenja stijene. Prilikom radova na objektima prihvatnog terminala za ukapljeni plin na otoku Krku potrebno je bilo ukloniti elemente starog pristana, odnosno četiri podvodne utvrdice. U tu svrhu proveden je program opsežnih mjerenja utjecaja miniranja na okolinu, u vidu praćenja djelovanja tlačnog udarnog vala u vodi te mjerenja nastalih brzina oscilacija na pilotima. U radu su opisana, kako projektna rješenja parametara miniranja, tako i program mjerenja u svrhu zaštite okoline te analiza dobivenih rezultata mjerenja.

Abstract (english)

Blasting is a modern technique for destroying and crushing rocks, materials and objects with the energy of explosives. The action of a detonated explosive charge in a mine bore causes stresses that lead to fracturing and crushing of the rock. During the works on the facilities of the reception terminal for liquefied gas on the island of Krk, it was necessary to remove elements of the old wharf, i.e. four underwater fortifications. For this purpose, a program of extensive measurements of the impact of blasting on the environment was carried out, in the form of monitoring the action of the pressure shock wave in the water and measuring the resulting velocities of oscillations on the piles. The thesis describes both the project solutions for the blasting parameters, as well as the measurement program for the purpose of environmental protection and the analysis of the obtained measurement results.
