ABSTRACT  Full text (pdf)

In the modern mining,  best efficient organization by obtainingsolid minerals, is getting with explosives utilization for blasting, with the growth ofsignificance in the exploitation of mineral resources in the open pit mines with large capacities. In this paper technological stages of drilling and blasting, that aredemandingfrom 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.
 
Key words: economycs, exploitation, blasting, explosives
