QUALITATIVE CHARACTERISTICS OF BAUXITE „OŠTRELJ“ NEAR BOSANSKA KRUPA

Qualitative characteristics of bauxite deposit „Oštrelj“ are defined through extensive laboratory testing of chemical and mineralogical-petrographic composition, and geomechanical characteristics. Chemical composition has shown that it is a relative poor bauxite with low Al/Si module (2,28). Low values of Al/Si module are result of lower Al2O3 conc...

COMPARISON OF THE RESULTS OF CALCULATION OF GEOLOGICAL RESERVES OBTAINED BY MANUAL METHOD OF GEOLOGICAL BLOCKS AND CALCULATIONS BYMODERN SOFTWARE

This paper presents the results of the calculation of coal reserves obtained by classical method (calculation method of geological blocks), which were compared with the results obtained by the calculation using software. Since this area was explored for long period of time and elaborates were done in past, we came to an idea to compare results from...

THE VULNERABILITY DETERMINATION OF GROUNDWATER BODIES IN SOUTHEASTERN BOSNIA ACCORDING TO DRASTIC, GLA AND EPIK METHODS

The vulnerability results of groundwaterbodies of southeastern Bosnia are shown in this paper. On the examined area 27 groundwater bodies were extracted, where 12 groundwaterbodies are in rocks with intergranular porosity and 15 groundwaterbodies are in rocks with karst-fissure porosity. All of the groundwater bodies were analysed through DRASTIC, ...
