Construction of the geological model of the "Knurówa"deposit and its application to the exploitation design Piotr Sosnowski, Dominik Galica E3s Web of Conferences, 2024 The “Knurów” deposit is characterized by intense and rich fold and fault tectonics. The model of the “Knurów” deposit includes 11 seams belonging to the Orzesze, Ruda Śląska and Siodłowe layers. Each of these seams is recognized by boreholes, but also properly documented by mining, which greatly facilitates the modelling of its surface. The article addresses selected issues related to the construction of a three-dimensional model of the deposit. The method of modelling the surface of the terrain and the erosion surface of the Carboniferous is presented, which are used to calculate the location of subcrops of modelled seams and to predict the deformation of the terrain under the influence of mining. The general principles of fault modelling are presented, and so are ways of designing mining surfaces in longwalls passing through a fault. In the analysed deposit there are also seam splits. The article discusses the principles adopted for the development of the deposit model and its visualization, as well as the use of a dedicated algorithm for calculating the location of mining surfaces in such zones.
Quality management in a 3D geological model - reliability of predicted hard coal quality parameters Piotr Sosnowski, Artur Dyczko, Paweł Kamiński E3s Web of Conferences, 2024 This paper presents some of the results of the project undertaken in JSW SA, which aim was to create a three-dimensional model of the deposits that make up the company and schedule company’s production. The assessment of the quantity of coals without analysis of qualitative data, i.e. physicochemical parameters, coking parameters, and optical petrographic analysis is not suitable for obtaining commercial contractors. To obtain information on the quality of the coal seam, the geological service of the mine takes coal samples. In the stratigraphic model and quality model, dedicated interpolators are used for interpolation and extrapolation. In the seam quality model, the most optimized interpolators are Inverse and Height. Modelled parameters such as volatile parts content and random vitrinite reflectivity were analysed in detail. The Height interpolator looks for both a random and a linear dependency. It extracts random changes locally while searching for linear dependencies and extrapolates them to a deposit area that does not have qualitative data. There is a risk of extrapolating a given value to infinity. Nevertheless, the amount of data and the area modelled allows you to close its scope at an acceptable level. A separate POLYGON interpolator based on mxl express surfaces was created to map coal type range. It uses interpolated quality parameters at a given location, generating a range of a particular type of coal. Setting the trend of variability makes it possible to predict higher coal types in deeper, unrecognized batches of deposits according to documented variability in parameters.
