    Deformacje powierzchni w otworowej Kopalni Soli »Barycz« w likwidacji czy mogą jeszcze powstać zapadliska?
    (2007) Mazurek, Jakub Kazimierz
    The solution exploitation of salt in the Barycz mine (started in 1924) resulted in continuous and discontinuous (cavity) rock mass deformations. The excavation finished nine years ago, but the deformations may occur for several dozen years. The paper discuss the deformation process, measurements and documentation of final deformations. It also shows the difference between actual deformations and the prognosis and the prognosis of deformations after the year 2000. The regions where deformation indexes may range values typical for I surface category were identified and also regions with cavity hazard.

    Prognozy deformacji górotworu w polu Pagory kopalni Barycz po podsadzeniu komór poeksploatacyjnych
    (Wydawnictwa AGH, 2010) Mazurek, Jakub Kazimierz
    The solution mining of salt was performed in (liquidated) Barycz mine for 75 years. It produced several sinkholes and continuous deformations. The excavation process was finished in 1999. In spite of partial backfilling of 10 excavation caverns in Tomana region sinkhole hazard is still active. This paper shows description of excavation process, the results of shape and geometry measurements with echosounder and the level of cavern backfilling. The forecast of deformations after the end of backfilling process is also presented.
