Stability Analysis of the Horizontal Geodetic Network at the Tailings Disposal Site Jazbec

V nalogi je obravnavana horizontalna geodetska mreža za nadzor stabilnosti odlagališča rudarske jalovine Jazbec. Najprej so na kratko predstavljena osnovna načela zasnove mrež in geodetske metode za merjenje premikov in deformacij. Sledi opis postopka deformacijske analize po metodi Hannover. Predstavljen je tudi postopek testiranja značilnosti premikov, v katerem kot testno statistiko uporabimo razmerje med premikom in njegovo natančnostjo. Osrednji del naloge predstavlja izvedba deformacijske analize za osnovne točke v horizontalni mreži Jazbec. Izvedli smo jo na osnovi meritev, opravljenih v sedmih terminskih izmerah. Obravnavali smo pare zaporednih izmer ter pare ničelne in posamezne kasnejše izmere. Ugotovljena je bila nestabilnost osnovnih točk S5 in S4 ter nekateri manjši premiki drugih osnovnih točk. V zadnjem delu naloge so izračunani premiki nestabilnih osnovnih točk in točk na objektu pri različno definiranem geodetskem datumu. Premiki so tudi grafično predstavljeni.In this thesis the horizontal geodetic network, established for deformation monitoring of the tailings disposal site Jazbec, is discussed. In the first section, basic principles of network design and geodetic methods for measurement of displacements and deformations are briefly presented. Afterwards, the procedure of Hannover approach to deformation analysis is described. The procedure for testing point displacement, that use the ratio between the displacement\u27s size and its accuracy as a test statistic, is also explained. In the middle section, the deformation analysis for reference points of the network Jazbec is carried out. The data that is used, was collected in seven epochs. Instability of reference points S5, S4 and some minor statistically significant displacements of some other reference points are identified. In the last section, the displacements of unstable reference and object points are calculated and statistically tested. The displacements are also graphically presented
