Abstract

Kumulativni eksplozivni naboji kod kojih je jedna dimenzija značajno veća od drugih nazivaju se kumulativni rezači. Kumulativni rezači imaju sposobnost usmjeravanja energije oslobođene detonacijom u pravac. Usmjeravanje energije se postiže izradom kumulativnog prostora pravilnih dimenzija i oblika u eksplozivnom punjenju. Ukoliko se kumulativni prostor obloži tankim slojem materijala, u pravilu metala, dodatno se povećava djelovanje kumulativnog naboja na ciljani objekt. U okviru ovog diplomskog rada opisan je postupak postavljanja kumulativnih rezača, pripreme objekata za rušenje, te same metode rušenja objekata kumulativnim rezačima. Da bi se provjerio utjecaj vrste eksploziva na učinkovitost kumulativnog rezača, proveden je eksperiment sa 6 kumulativnih rezača s tri tipa eksploziva.

Abstract (english)

Shaped charges in which one dimension is significantly larger than the others are called linear shaped charges. Linear shaped charges have the ability to direct the energy released by detonation in a direction. Energy directing is achieved by creating a cumulative space of regular dimensions and shapes in an explosive charge. If the cumulative space is coated with a thin layer of material, usually metal, the effect of the cumulative charge on the target object is further increased. Within this diploma thesis, the procedure of installing linear shaped charges, preparation of buildings for demolition, and the methods of demolition of buildings with cumulative cutters are described. To check the influence of the type of explosive on the efficiency of the linear shaped charges, an experiment was performed with 6 linear shaped charges with three types of explosives.
