Izmera geodetskih mikromrež Plaz in Vrtine za ugotavljanje premikov odlagališča Boršt Rudnika Žirovski vrh : magistrsko delo

Rakovec, Jošt (author), Savšek, Simona (mentor), Kogoj, Dušan (co-mentor)

Odlagališče hidrometalurške jalovine Boršt se z geodetskimi metodami spremlja že od leta 1988. Na odlagališču in v okolici sta vzpostavljeni terestrični geodetski mreži Plaz in Vrtine-2. Obe mreži sta v celotnem obdobju geodetskih izmer doživeli kar nekaj sprememb, najpogosteje zaradi sanacije samega odlagališča. Magistrska naloga opisuje izmero obeh mrež. Z izravnavo smo določili horizontalne koordinate in višine točk ter ocenili njihove natančnosti. Mreži smo izravnali ločeno in skupno ter primerjali rezultate. Na osnovi predhodne izmere smo s statističnimi metodami preverili verjetnost premikov točk tako v ločenih mrežah kot v skupni mreži. Rezultate posredne izravnave po metodi najmanjših kvadratov smo primerjali z rezultati S-transformacije, s katero smo ugotavljali morebitne premike danih točk. Na osnovi analiz smo ugotovili, da je potrebno določiti nov geodetski datum.

• Title: Measurement of geodetic micro-networks Plaz and Vrtine for determining the movements of the landfill Boršt of mine Žirovski vrh : master thesis

Abstract

Landfill of the Boršt hydrometallurgical shaft has been monitored using geodetic methods since 1988. Terrestrial geodetic networks Plaz and Vrtine-2 have been established at the landfill and in the surrounding area. Both networks have undergone quite a number of changes throughout the geodetic surveying, mostly due to the repairing of the landfill itself. The master's thesis describes the measurement of both networks. The horizontal coordinates and the heights of the points were determined by adjustment process and their accuracy was estimated. We adjust the networks separately and total and compared the results. Based on the previous measurement, the probability of moving points in separate and total network was verified by statistical methods. The results of the indirect least-squares equalization were compared with the results of the S-transformation, which was used to determine possible movements of given points. Based on the analyses, we determined that it is necessary to set a new geodetic datum.
