CHOICE OF EXCAVATION METHOD OF THE ORE DEPOSITS
The paper defines choice of the optimal excavation method for ore deposits, which are characterized by general irregularity due to their origin, occurrence and different content of the usable minerals. In such complex conditions, the choice of the excavation method is defined according to: the natural characteristics of the deposit and according to...

CONTROL FACTORS OF IRON MINERALIZATION IN THE METALLOGENY OF THE LJUBIJA ORE REGION
The control factors of mineralization in the Ljubija ore region are stratigraphic, lithological, magmatogenic, structural-tectonic and hypergenic. The distribution of iron ores in the Ljubija ore region is primarily controlled by the spread of the Olistostrome member of the Carboniferous Javorik flysch formation. Only that member, whether uncovered...

ANALYSIS OF ORE LOSSES AND DILUTION FACTORS IN BAUXITE UNDERGROUND EXPLOITATION
In this article are presented the analysis of ore losses in bauxite underground exploitation as well as the manner and possibility to increase recovery factor of ore deposit and exploitation with minimum of diluted ore with overburden. The largest losses of ore are the caracteristics of the mining process itself and the results of model studies of ...

IMPORTANCE OF OLISTOSTROME MEMBER FOR METALLOGENY OF LJUBIJA IRON ORE DEPOSITS
Ljubija mining area is built of more formations that belong to the Carboniferous, Permian, Triassic and Cenozoic. From all of these, only two are metalliferous to iron: Javorik formation with olistostrome member and Neogene-Quaternary of Prijedor basin. The first includes primary siderite and ankerite partially limonitised ore and in the second onl...
