Abstract

Zbog sve veće urbanizacije javlja se potreba za izvođenjem opreznih miniranja kako bi se što manje oštetila okolna stjenska masa te da se očuva njena fizikalno-mehanička svojstva van zone miniranja i da se smanji potencijalno štetni utjecaj miniranja na okolne objekte. Tipični eksplozivi koji se koriste u rudarstvu ne zadovoljavaju tražene zahtjeve za izvođenjem opreznih miniranja stoga je potrebno odrediti minersko-tehničke karakteristike emulzijskih eksploziva smanjene gustoće. Ispitivanjem na poligonu određen je kritični promjer i brzina detonacije za ispitivani emulzijski eksploziv smanjene gustoće iniciran trenutnim električnim detonatorom i trenutnim električnim detonatorom s pojačnikom.

Abstract (english)

Due to increasing urbanization, there is a need to carry out careful blasting in order to damage the surrounding rock mass as little as possible and to preserve its physical and mechanical properties outside the blasting zone and to reduce the potentially harmful impact of blasting on surrounding objects. Typical explosives that are used in mining do not meet the requirements for careful blasting, so it is necessary to determine the miningtechnical characteristics of low-density emulsion explosives. The critical diameter and detonation velocity of the tested low-density emulsion explosive, that was initiated by an instantaneous electric detonator and an instantaneous electric detonator with booster, were determined by field tests.
