Geological and technological viewpoint on 3D Deposit Model – examples of use in Pniówek Coal Mine

Abstract

During the more than 3 years of the “Quality” program at JSW S.A., a geological database has been built from scratch, collecting data from all exploratory boreholes, roadway profiling and the results of chemical analyses in one place – placing particular emphasis on parameters affecting the quality of coke. Working with digital databases requires new competencies for geologists – the ability to efficiently obtain information ready for further processing. As intended, the geological model became the basis for forecasting the quantity and quality of mined coal used in coke production. In the course of the work, a discrepancy became apparent between the geological interpretation of the structure of the deposit – as understood by the assumptions of the geological documentation, and the technological conditions of mining. The article presents resulting changes in the approach to modeling lithology and quality parameters. In addition, examples of the application of the geological database and the geological model in the daily work of the geological department are presented.
