20.500.12556/RUL-181217 Primerjava metod izračuna zalog in virov mineralnih surovin z uporabo metode vzporednih profilov in 3D modeliranja magistrsko delo Comparison of methods for calculating mineral reserves and resource estimates using parallel section method and 3D modeling Magistrsko delo obravnava določanje preostalih zalog tehničnega kamna, dolomita, v pridobivalnem prostoru kamnoloma Zgornji Gabernik s primerjavo zakonsko predpisane metode vzporednih profilov in 3D volumetričnega izračuna na osnovi UAV fotogrametrije. Namen raziskave je bil preveriti skladnost rezultatov, izpostaviti ključne vire odstopanj ter oceniti praktično uporabnost obeh metod za načrtovanje odkopa in strokovno podporo odločanju. Pri metodi vzporednih profilov je bila izdelana serija desetih prečnih profilov (P1–P10), na podlagi katerih je bilo območje razdeljeno na enajst volumetričnih blokov. Prostornine blokov so bile izračunane z ustreznimi geometrijskimi enačbami (linearna interpolacija, trisekcija, klinasta oblika), izbira pa je bila odvisna od razlike med presečnimi površinami sosednjih profilov. Skupna prostornina preostalih zalog je bila določena na 1.048.746 m³, od tega bilančne zaloge znašajo 83.504 m³, izvenbilančne pa 965.242 m³. 3D pristop temelji na RTK-georeferenciranem UAV zajemu in fotogrametrični obdelavi posnetkov, iz katerih so bili pripravljeni digitalni produkti obstoječega stanja (DTM 2024) ter referenčna površina projektiranega končnega stanja (DTM-P). Neto prostornina, določena kot razlika med TIN-površinama obeh stanj znotraj iste prostorske omejitve, znaša 900.815,63 m³, kar je približno 14,1 % manj kot rezultat metode profilov. Rezultati kažejo, da se metodi smiselno dopolnjujeta. Metoda profilov omogoča uradno kategorizacijo in klasifikacijo zalog, 3D pristop pa zagotavlja ponovljiv kontrolni izračun ter učinkovit vpogled v prostorske spremembe terena. The master’s thesis examines the determination of remaining reserves of technical stone (dolomite) within the extraction area of the Zgornji Gabernik quarry by comparing the legally prescribed parallel profile method with a 3D volumetric calculation based on unmanned aerial vehicle (UAV) photogrammetry. The study aims to verify the consistency of the results, identify key sources of discrepancies, and assess the practical applicability of both methods for excavation planning and professional decision-making support. In the parallel profile method, ten transverse profiles (P1–P10) were produced, dividing the area into eleven volumetric blocks. Block volumes were calculated using appropriate geometric equations (linear interpolation, trisection, wedge-shaped), with the choice depending on the difference between the cross-sectional areas of adjacent profiles. The total volume of the remaining reserves was determined to be 1,048,746 m³, of which economic (balance) reserves amount to 83,504 m³ and subeconomic (off-balance) reserves to 965,242 m³. The 3D approach is based on an RTK-georeferenced UAV survey and photogrammetric processing of the images, from which digital products of the existing condition (DTM 2024) and the reference surface of the designed final state (DTM P) were created. The net volume, defined as the difference between the TIN surfaces of both states within the same spatial boundary, is 900,815.63 m³, approximately 14.1% lower than the result obtained with the profile method. The results show that the two methods complement each other effectively. The profile method enables official categorization and classification of reserves, while the 3D approach provides a repeatable control calculation and efficient insight into spatial changes in the terrain. zaloge mineralnih surovin metoda vzporednih profilov UAV fotogrametrija 3D modeliranje volumetrična primerjava mineral resource reserves parallel profile method UAV photogrammetry 3D modeling volume comparison true false false P.
