ECONOMIC COST ANALYSIS OF DRILLING AND BLASTING DEPEND OF DRILLING AND BLASTING PARAMETERS AT QUARRY ''DOBRNJA'' NEAR BANJA LUKA

Abstract

In the modern mining, best efficient organization by obtaining solid minerals, is getting with explosives
utilization for blasting, with the growth of significance in the exploitation of mineral resources in the
open pit mines with large capacities. In this paper technological stages of drilling and blasting, that are
demanding from the technological aspect, had been economicaly analyzed, because of the specific
working environment by limestone quarries. The aim is to arrive the optimal combination (with the
technological and economic aspects) of explosives in an explosive charge that would be used in the
future work of the quarry, where technical-technological efficiency follow and economical organizing
of completely production process.
