Abstract

This paper presents a case study in the application of geostatistics in the analysis and adaptation of representative values of the geotechnical parameters at coal deposits. In order to select the most reliable geotechnical values for the design process of open cast pit excavations of large heights, different pools of laboratory data sets have been processed. The following critical geotechnical parameters were investigated: volume weight, angle of internal friction, and moisture content. By applying the correct geostatistical tools, and in comparison with practical experience and removal of obvious outliers from the datasets, for one of the deposit are prepared the so-called “geotechnical domains” are prepared, shown in the form of spatial distribution maps of the analysed parameters. Advantages of the applied geostatistical approach are seen in enabling higher confidence when performing slope stability analysis, selection of the most optimal geometry of the mines, lesser overburden quantities, protection of the environment, production cost cutting, and time saving.
