Data preparation for digital modelling of the coal seams in the South Moravian Lignite Coalfield (Czech part of the Vienna Basin)
In the contribution data preparation for digital modelling and assessing the Kyjov Seam (Pannonian, zone B of the Vienna Basinstratigraphy) and the Dubňany Seam (Pannonian, zone F) is presented. The seams occur partly as unit seam and partly as seam splitin up to four benches. Almost 3000 holes were drilled in the area in the last 50 years. Data about lithological logs, laboratory resultsand other measurements were gathered, uniformed, and stored in digital database. Input data for modelling, which were the thicknessand average values of analytical parameters in set thickness in each data point (drill hole), were derived from the primary data storedin database by designed software. The thickness was defined in five ways in each drill hole. Firstly as the geological thickness to modelnatural geometry of the seam and secondly as deposit thickness to model only part of the seam with required quality. Deposit thicknesswas defined in four variants according to limit parameter of maximal average ash content value of 50, 40, 35, and 30 % in the seamin borehole.
