The article presents the results of the definition of a new methodology for assessing the risk of flooding a shallow slotted mine, which was carried out on the square above the Wieliczka Salt Mine, which is a world heritage. Vertical stresses are estimated on the basis of the theoretical state of rock mass deformation in the area of test chambers. In addition, the risk for chambers indicated in the zone was calculated based on the theory of arctic pressure. The final stage of the study was spatial analysis, which led to the identification of chambers, potentially subject to the influence of other risk factors. The results of the study proved that a combined spatial analysis with a theoretical solution can lead to a reliable risk assessment methodology in mining.
