Statistična ocena izračuna rudnih zalog v rudniku urana Žirovski vrh : diplomska nalogaŠirca, IrenaNamen naloge je bil preveriti, ali je metoda, ki so jo uporabili v Rudniku urana Žirovki vrh (RUŽV) leta 1984 za izračun rudnih zalog na celotni populaciji rudnih blokov in rudnih prebodov, ... zadovoljiva ali ne. Pri izračunu so uporabljali naravne vrednosti spremenljivk debeline orudenja, vsebnosti uranovega oksida, količine rude in količine oksida. Porazdelitve spremenljivk debeline in vsebnosti odstopajo od normalne in do izrazito desno asimetrične. V ta name sem napravila primerjave metode asimetrične sredine s tremi drugimimetodami, ki upoštevajo pribli\no logaritmično porazdeljenost vrednosti spremenljivk v treh vzorcih po 30 rudnih blokov. Primerjave so pokazale, da je metoda, uporabljena v RUVŽ, sprejemljiva za izračun zalog zaradi majhnih odstopanj izdov treh metod. Bolj je primerna za ziračun debelin, ker so bližje normalni porazdelitvi kot koncentracija. Kor najprimernejša se je izkazala metoda znane populacijske variance zaradi najmanjših relativnih napak ocen srednjih vrednosti. Ta metoda daje tudi najvišje vrednosti debeline blokov, koncentracije U3O8 v bloku, količine rude in količine oksida U3O8 v bloku.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : Širca, 1990Language - slovenianCOBISS.SI-ID - 145502
