Modelování a hodnocení ložiska kaolinu

Abstract

The presented dissertation deals with spatial modeling of the kaolin deposit. The aim of this work is to create a 3D model of the kaolin deposit. This 3D model will not only enable optimal kaolin mining based on archive data, or data from additional research and ongoing mining, but it can also be used to perform detailed inventory estimates based on specified usability conditions. The dissertation describes spatial modeling of kaolin deposits. There are described step by step of methodical procedure of creation, evaluation and visualization of a 3D model of the deposit. The implementation of this methodology is performed in the Visual Studio 2019 with the use of Surfer and Voxler objects from Golden Software. This methodology, along with the developed software allows a user to create a variant dynamic model for the same or similar types of deposits, enables a quick update of the model when changing the input data on the basis of new mining exploration or when changing of modeling parameters. The methodology leads to a more advanced evaluation of deposits, including variant estimates of reserves by to specified conditions of usability. The developed methodology and relevant software for the evaluation of the deposit is illustrated on a specific kaolin deposit Jimlíkov – East, located near the village Jimlíkov about 5 km west of Karlovy Vary. The work is divided into several chapters. The introductory part is followed by a chapter which is devoted to the basic information of the selected kaolin deposit, on which this work is presented. There is a detailed description of the geological structure of this deposit, quality and technological characteristics and the last recalculation of reserves performed in this area. The next chapter describes the individual steps of the methodological procedure for modeling a kaolin deposit. From the evaluation of all available materials, visualization of spatial data, statistical processing of the parameters, modelling of the bottom and the top of the kaolin deposit up to estimated the reserves of the deposit and visualization of categories of the blocks of reserves processed using various types of 2D and 3D visualizations. The next chapter implements a procedure, which is based on the created methodology, processes the obtained data in the Visual Studio 2019 environment. The advantages and possibilities of using the created software are described in the end.
