SUMMARYThis 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 Elaborate with results obtained through software supported analysis of deposit. The compared results indicate that the results gain through classical calculation and through use of software vary within the permissible tolerances for this kind of calculation.

The use of modern global navigation system (GPS-GNSS) is massively being used in the modern research. Therefore, the use of these methods in science can do much to facilitate scientific research work. In this scientific work we analyzed the database obtained by the GPS device and field testing engineers, and the data is used to produce maps of the field, engineering geological map and we recorded elements of landslide that were used for mapping (cracks, landslide mass, water sources, forehead scar and glide plane). Based on the results obtained, we made morphology of landslide and landslide engineering geological map in scale 1:500.

There are only a few limestone mines in Bosnia and Herzegovina that provide the mineral raw material for industrial production. As a result, the experience in planning and designing such quarries is lesser than in designing the quarries for construction. Limestone from "Vijenac" deposit is an industrial mineral raw material, which is used for the production of soda (light, heavy and bicarbonate), cement, nitrogen fertilizer named "KAN", and is also used in construction and road construction. The use of limestone as a mineral raw material in industrial production requires more attention to the chemical composition of limestone than to the physical-mechanical characteristics. The paper presents a solution to this problem by creating a block of models of exploitation reserves of limestone, which enables foresight of the chemical composition of limestone, both in each floor partially and during the period of exploitation. The block model was created on the basis of the updated state of works, the projected contour of limestone surface mine and the exploration works' database. The block model uses the following: CaCO3, CaO, SiO2, Al2O3, Fe2O3, bulk density, category of reserves and the purpose of the mineral raw material, i.e. for industry or construction. The block model analysis has determined that the northern part of the mine, from the floor E-612.5 to E-525 meters a.s.l., does not meet industrial requirements in terms of chemical composition of limestone. Therefore, limestone from this part of the surface mine will be used for construction purposes. These quantities of limestone are about 2.6x106 m3. Limestone from the southern part of the surface mine meets the industry requirements. Its quantities are about 8.47x106 m3.
