Perspectives for Development of Technical Building Stone- Limestone in the Republic Srpska

Abstract

Curent situation of raw material base and study of limestone like construction stone deposits in the Republic of Serbian were relatively poorly considered during the last decades, and the main problems are the following: low production capacity,fragmentation of production, needs for raw materials homogenization and delivering of standard quality, undeveloped market, the recession of the domestic economy and the economies in the region, the relatively low level of exploration by many deposits, especially lack of knowledge of the occurrence legality for certain types and quality of raw materials and lack of complete quality indicators for raw material, which sometimes causes the utilization of only the highest quality deposit parts .This paper provides an overview of active quarries in the Republic Srpska with exploitation of limestone like technical building stone and present an attempt to determine the basic quantitative and qualitative characteristics of the raw material and the current working conditions at these quarries. The purpose of such a review would be in an effort to create a clearer picture about production, market, social and other aspects of the limestone exploitation in the Republika Srpska and the realistic possibilities of maintaining and developing of these mineral resources utilization, which can certainly be interesting for the development of many other industries in the Republic Srpska.

Calculation of Drilling and Blasting Parameters for Quarry ''Dobrnja'' Near Banja Luka

“…During the execution of drilling-blasting works in the real conditions on the ground, it will come to the optimal parameters of drilling and blasting. In the selection of drilling equipment, make sure that the drill has the ability to drill inclined boreholes and wells of different diameters, which allow the determination of the optimal diameter drilling [4].…”
