Abstract
Eksplozivi smanjene gustoće, zbog njihovih detonacijskih i eksplozivnih svojstava, adekvatan su izbor za korištenje u urbanim sredinama na malim udaljenostima od objekata. Smanjenje udarnog djelovanja detonacijske energije prenešene na stijensku masu, može smanjiti intenzitet seizmičkog utjecaja. Eksplozivne smjese, na bazi emulzijske matrice, senzibilizirane su materijalima znatno manje gustoće i postižu povoljna svojstva određena laboratorijskim testovima. Budući da je brzina detonacije proporcionalna gustoći eksploziva, opisana istraživanja provedena su sa svrhom određivanja granične gustoće smjese emulzijskog eksploziva i ekspandiranoga polistirena uz postizanje stabilne detonacije te određivanja zavisnosti brzine detonacije od gustoće smjese. Na temelju dobivenih rezultata laboratorijskih ispitivanja, u ovom radu su prikazana mjerenja brzine detonacije, brizantnosti, radne sposobnosti i osjetljivosti na iniciranje na uzorcima većeg promjera.
Abstract (english)
Abstract: Low density explosives, due to their detonation and blasting properties are appropriate choice to be used in urban areas, at short distances from structures. By decreasing the impact share in detonation energy transferred to rock mass, the intensity of seismic influence could be reduced. The emulsion matrix based explosive mixtures, sensitized by the materials with significantly lower density have reached favorable properties determined by laboratory scale tests. Since the velocity of detonation is proportional to the density of an explosive, the described research is carried out in order to determine the borderline density of the mixture of an emulsion explosive with expanded polystyrene while achieving stable detonation, and to determine the dependency between the velocity of detonation and the density of mixture. Based on the laboratory test results, velocity of detonation, brisance, work ability and initiation sensibility measured on larger diameter samples are determined in this paper.
