Kurzfassung:
Until 2001, gypsum was extracted in an underground operation from the gypsum mine Preinsfeld, Austria. The initially used mining method was room and pillar mining. Due to the former extraction on sublevels, there are still pillars of approximately 4 m height left to mine. Within the scope of a master thesis, the remaining amount of gypsum in the mine was evaluated and an appropriate mining method to extract it was developed. The extraction method of blasting was compared to machine excavation with a roadheader. After the decision was taken in favor of the roadheader, the hauling fleet was adjusted to it. By using the geology and mine planning software Geovia Surpac™, a three-dimensional model of the mine was created for different mining methods. A classical room and pillar mining method was planned for different tunnel profiles and then compared to an adjusted cut and fill stoping method with backfill. After consideration of technical, economical and safety factors, the decision was made in favor of the cut and fill mining method. Therefore, a detailed study on the mine planning, mine ventilation, costs and life of mine was conducted.
