Abstract

Promatranje i predviđanje prirode i veličine zona oštećenja u okolnoj stijenskoj masi
kao i razumijevanje mehanizama frakturiranja i drobljenja stijenske mase jedan je od
najvažnijih parametara potrebnih pri projektiranju miniranja radi dobivanja željene
granulacije odminirane stijenske mase i smanjenja štetnih utjecaja miniranja na okoliš. U
radu je dan prikaz postojećih teorija drobljenja i loma stijenske mase eksplozivom kao i
veličina zona oštećenja. Opisana istraživanja provedena su modificiranim podvodnom
metodom pri čemu su mjereni tlakovi detonacije u vodi, odnosno udarnog vala u vodi,
uzrokovanih otpucavanjem inicijalnih sredstava različite mase eksplozivnog punjenja u
betonskim blokovima različitih volumena. Optimalna, potrebna energija detonacije
određena je na bazi izmjerenih tlakova i stupnja drobljenja blokova.

Abstract: The prediction and observation of the nature and dimensions of damaged zones in
surrounding rock and understanding the mechanisms of fracturing and crushing of rock
mass with explosives is one of the most important parameters in blasting design to obtain
preferred granulation and reducing damaging effects of blasting on environment. In this
paper an overview of existing theories of fracturing and crushing the rock mass with
explosives and of dimensions of damaged zones is given. Described researches are
performed by the modified underwater test during which detonation pressures related with
shock wave pressures in water were measured. Measured pressures were caused by
blasting of detonators charged with different explosive mass, blasted in different volumes
of concrete blocks.
