The old workings may still generate mining menace hazard around the Polish historic salt mines of Wieliczka and Bochnia, despite the fact that adequate protection support have been provided along the underground tourist routes. The water and collapse hazards dominate in underground salt mines. Water hazard is manifested by leaks, excessive leaching...

The catastrophic mine failure resulting from the inrush of water into the Wapno Salt Mine was probably caused by a fracture in the roof protection shelf. The purpose of the present study was to apply the method of the homogenization of the multi-level room-and-pillar structure in the Wapno Salt Mine for 3D+t modelling of the elastic-viscous medium...

Occurrence of land surface subsidence is a result of rock salt extraction. The process is observed by geodetic measurements. On the Palędzie I salt mining field, such measurements are conducted every five years. The most recent series of measurements was carried out in 2009. The analysis of land levelling results indicated that a twin-centre subsid...

The convergence measured in the Polish salt mines was used to identify the relationship between the room closure and geological and mining conditions, for the identification of the phenomenon of the closure of a single room or the group of rooms, for the estimation of the pillar loads, to identify the geomechanical properties of rock mass and to id...

The present research was aimed at comparing the application of various values of the m and n parameters and then presenting their influence on the areal convergence of the gallery in the salt rock mass. The present paper is a continuation of the previous research (Maj 2008) that was conducted on convergence. The results of this present research wil...
