Abstract

Miniranje predstavlja skup kompleksnih radnji za koje je uz pravilne proračune i metode važna i sigurnost. Sigurnost i sve veća točnost se mogu odrediti iz već postojećih sličnih radnji na sličnim okruženjima, no ako se i jedan parametar promijeni vrlo važno je uz pomoć kontrolnih opažanja postići najoptimalnije uvjete. Seizmički utjecaji miniranja vrlo su važan dio prilikom izrade plana miniranja, utjecaji se temelje na nizu normi, proračuna i raznih preporuka. Osnovni parametar na kojem se bazira daljnja aktivnost prilikom proračuna je brzina oscilacije tla. Do sada je poznato nekoliko metoda koje matematički opisuju navedenu problematiku. Danas uz sve veće širenje gradova i naselja, javlja se potreba sa sve zahtjevnijim miniranjima koja uzimaju u obzir objekte u blizini miniranja. Kako bi se točno odredio utjecaj i dozvoljena količina eksploziva kod koje neće doći do oštećenja objekata koriste se razne kontrolne metode i ispitivanja. Cilj rada bio je prikazati kako se uz što više kontrolnih mjerenja postižu točniji rezultati, te kako je miniranje i sve popratne aktivnosti moguće obaviti u blizini naseljenog mjesta uz dodatne otežavajuće okolnosti kao što su podzemni spremnici za vodu, dalekovodi i telefonski vodovi.

Abstract (english)

Blasting is a set of complex actions for which, in addition to proper calculations and methods, very important is safety. Safety and accuracy increase can be determined from pre-existing similar actions in similar environments, but if even one parameter changes, it is very important to achieve the most optimal conditions with the help of control examination. The seismic impacts of blasting is a very important part when designing a blasting plan, the impacts are based on a series of norms, budgets and recommendations. The basic parameter on which further activity is based during the calculation is the speed of oscillation. Oscillation velocity far, several methods that mathematically describe this problem, are known,. Today, with the increasing expansion of cities and settlements, there is a need for increasingly demanding blasting that takes place near account facilities. In order to accurately determine the impact and allowable amount of explosives that will not damage buildings, various control and testing methods are used. The aim of the work was to show how accurate results are achieved with as many control measurements as possible and how blasting and all accompanying activities can be performed in the vicinity of the settlement with additional aggravating circumstances such as underground water cisterns, transmission lines and telephone lines.
