    Możliwości zabezpieczenia komór Jakubowice w Kopalni Soli »Wieliczka«
    (Wydawnictwa AGH, 2011) d'Obyrn, Kajetan
    The Jakubowice complex is a substantial group of chambers in the eastern part of the central field of the Wieliczka Salt Mine. Examination of the technical status, based on excavation chamber observations, was confirmed by numerical geo-mechanical analysis. Both analyses proved that the most important issue for preservation of the post-exploitation chambers is geological structure of the surrounding deposits. Especially, the existence of waste rock layers, and also intensity of the chamber convergence process. Liquidation by filling of the chambers localized at the lowest level and preservation of the upper chambers, with historical value, shall prevent further degradation of this part of the salt mine. The important outcome of the undertaken analyses is providing evidence of the lack of direct hazards created by the chamber complex for the land surface.
