    The main aim of the final thesis was to create three-dimensional copper content models in selected parts of LGOM deposit by using geostatistical procedure of 3D ordinary kriging. The study was based on drillhole database from three areas of the Polkowice - Sieroszowice mine (Mo01, Po23, Pr03). The analyzed parameter (copper content) was estimated in 3D mesh with dimensions 1x1x0,2 m. Principles of accurate and correct copper content modeling were presented in thesis, especially with considering problems such as: samples regularization, anisotropy of copper variability, modelling boundaries of lithological series, the elementary block (miniblock) size, the choice of neighborhood parameters and the deposit inclination influence on procedure of $Cu$ content assessment. After the research it is recommended to carry out the estimation in Lubin Copper District based on 8 regularized samples with taking into consideration lithological differences and the deposit inclination.

    Trójwymiarowe modelowanie wartości parametrów złożowych metodą krigingu zwyczajnego 3D
    (Wydawnictwa AGH, 2009) Mucha, Jacek; Wasilewska-Błaszczyk, Monika
    The principles of 3D modelling of deposit parameters by means of geostatistical procedure of 3D ordinary kriging were outlined. The use of the procedure was illustrated by example of Cu content assessment in exploitation blocks in a one of the deposits Cu-Ag from Fore-Sudetic Monocline. A new classification of accuracy of mean Cu content estimation in exploitation blocks was proposed.
