Selected Aspects of Numerical Modelling of the Salt Rock Mass: The Case of the “Wieliczka” Salt Mine / Wybrane aspekty modelowania numerycznego masywu solnego na przykładzie kopalni soli „wieliczka”

Abstract

Each excavation or excavation complex intended to be backfilled or secured requires an individual approach, and conducting a detailed geomechanical analysis which will allow the selection of the appropriate manner of securing or backfilling or liquidation, and the order of performing mining works. The numerical model of the selected chamber or group of chambers must accurately reflect the reality and have an appropriately selected calculation model. The paper presents the selected aspects of numerical modelling of the “Wieliczka” salt rock mass. There are method of selection of geotechnical and rheological parameters of salt, the geometrization of the excavations continues and selection calculation model.
