Eksploatacja soli potasowych w Małopolsce wschodniej w czasach II Rzeczpospolitej - przyczynek do historii górnictwa solnego na Podkarpaciu
(Wydawnictwa AGH, 2010) Poborska-Młynarska, Katarzyna; Andrusikiewicz, Wacław
Potash deposits are not presently extracted in Poland. However, during the interwar period (1921-1939), the extraction and processing of potassium and magnesium salts - mainly sylvinite, langbeinitite and kainitite - took place in eastern Małopolska. The potash mines, operated by Society for the Exploitation of Potassium Salt (TESP), existed in Kałusz, Stebnik and Hołyń. Salt was extracted by a method of chamber mining with the use of drilling and blasting techniques, sometimes with rock or hydraulic fill transported from the processing plant. In 1938 the total output of the mines reached 567 000 tonnes of salt, with 2300 people employed. The outbreak of World War II put a definite end to this episode of Polish potash mining.

Kopalnie soli kamiennej w Rumunii - tradycja i czasy dzisiejsze
(Wydawnictwa AGH, 2010) Poborska-Młynarska, Katarzyna
The rock salt production in Romania has a long tradition since Roman Empire times. Today the salt is produced in underground mines and as salt in brine. The total production is around 2.6 mln Mg per year. Contemporary salt mining combines the rock salt exploitation with tradition by creating touristic routes, museums and sanatories in old mining openings. Three of several mines producing rock salt and brine are presented: Salina Praid, Salina Targu Ocna i Salina Cacica. The mines were visited by Polish Salt Mining Association (PSGS) during geological and mining seminar which took place in Romania from 10th to 14th July 2009.

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.
