Abstract

Eksplozivi su energetski materijali koji se primjenjuju u nizu aktivnosti današnjih proizvodnih tehnologija. Najveće količine eksploziva se utroše u rudarstvu za pridobivanje mineralnih sirovina i građevinarstvu za iskop različitih građevnih jama, tunela i drugih podzemnih objekta. Posebna i često nezamjenjiva primjena eksploziva je rušenje objekta primjenom energije eksploziva odnosno miniranjem. Primjena miniranja za rušenje objekata aktualizirana je u Hrvatskoj nakon nedavnih potresa u Zagrebu i Petrinji. Budući da Rudarsko-geološko-naftni fakultet Sveučilišta u Zagrebu jedini u Republici Hrvatskoj obrazuje stručnjake za primjenu eksploziva za različite namjene pa tako i za rušenje objekata miniranjem, studentskim radom su analizirani utjecaji pojedinih parametara miniranja na uspješnost rušenja dimnjaka tragom izvedenih projekta rušenja. Analiziran je utjecaj:vrste materijala i način izrade dimnjaka, oblika i veličina zaloma pri miniranju, raspored i punjenje minskih bušotina Istraživanje je provedeno u realnim uvjetima na modelima betonskih i ciglenih dimnjaka. Detaljno je prikaza proračun rušenja dimnjaka eksplozivom uz ukopnu potrošnju eksploziva i inicijalnih sredstva. Sva ispitivanja su izvedena na ispitnom poligonu Laboratorija za ispitivanje eksploziva Rudarsko – geološko naftnog fakulteta.

Abstract (english)

Explosives are energy materials used in a number of activities in today's production technologies. The largest quantities of explosives are used in mining for the extraction of mineral raw materials and in construction for the excavation of various pits, tunnels, and other underground structures. A special and often irreplaceable use of explosives is the demolition of an object by applying the energy of explosives or blasting. The use of blasting for demolition of buildings was used in Croatia after the recent earthquakes in Zagreb and Petrinja. As the Faculty of Mining, Geology and Petroleum Engineering of the University of Zagreb is the only one in Croatia that trains experts in the use of explosives for various purposes, including the demolition of buildings, the student work analyzes the impact of certain parameters of blasting on the success of chimney demolition. The effects analyzed were: types of materials and method of making chimneys, cuts shape and size during blasting, layout and explosive load of the chimneys The study was carried out in real conditions on models of concrete and brick chimneys. The calculation of chimney demolition with explosives with the total consumption of explosives and initial means is presented in detail. All tests were carried out at the test site of Explosives Testing Laboratory of the Faculty of Mining and Geology and Petroleum Engineering.
