    Ograniczenie migracji wód powierzchniowych i czwartorzędowych wokół otworu podsadzkowego TP-17 w Kopalni Soli Wieliczka
    (2007) Gonet, Andrzej; Stryczek, Stanisław; Brudnik, Krzysztof
    The Salt Mine Wieliczka has been subjected to a number of hazard during its 7 centuries history. The most important hazard comes from water. Prevention and protection works have been undertaken to minimize the risk. On the example of a backfilling well TP-17 there were presented: its location, tasks and causes of water migration to the mine, technologies of closing the well TP-17 and sealing up the neighboring rock mass, results of geoengineering works.

    Technologia likwidacji otworów podsadzkowych w kopalniach soli
    (2008) Gonet, Andrzej; Stryczek, Stanisław; Brudnik, Krzysztof
    Backfilling wells are performed for a variety of situations. After being used, these wells should be closed as soon as possible, because their technical state usually deteriorates. This is especially important for salt mines, where they can be potential pathways for water. The closing technologies used for the reservoir and beyond it were discussed on the example of a backfilling well TP-24, drilled to the chamber Sanguszko in the Salt Mine Wieliczka S.A. Techniques of scaling up the near-wellbore area with the borehole injection method, and employing packers and properly selected sealing slurries are described in the paper.
