W artykule przedstawiono różne koncepcje likwidacji Kopalni Soli „Siedlec-Moszczenica”. Zwrócono uwagę na próby wykorzystania jej wyrobisk w innych celach. W końcowej części tekstu opisano wybrany sposób likwidacji szybów (poprzez zasypanie) i wyrobisk poziomów eksploatacyjnych (wypełnienie solanką).

The construction of the Siedlec-Moszczenica Salt Mine began in the 1970s. Up to 1994, excavations measuring approx. 25 km in length were drilled and their volume was approx. 250,000 m3. Between 1988-1994, i.e. the period during which the mine was operational, approx. 1.75 million tonnes of salt was mined, which is almost 1% of total deposit resources. After 1989, the coal lost its economic basis in terms of mining salt, and the idea of using its excavations as natural gas storage locations turned out to be uneconomical, which led to the decision to decommission the mine, the process of which began in November 2011. Instead of using sand burying, the analysis of decommissioning costs offered the possibility of using a self-setting mixture based on salt rubble, which is obtained from the reconstruction of historic Bochnia Salt Mine excavations. Brine supplied naturally to the historic Bochnia Salt Mine will be used to fill inactive mining excavations of the Siedlec-Moszczenica Salt Mine, which is being decommissioned. Brine will be pumped through a pipeline installed in the shaft, and if the pipeline blocks, brine will be pumped through a drain hole drilled for this purpose. The adopted method for decommissioning the Siedlec-Moszczenica Salt Mine excavation ensures that the salt deposit is secured, the decommissioning costs, as well as the costs of decommissioning of a non-historic part of the Bochnia Salt Mine and the running costs of maintaining its excavations are optimised, which, therefore, results in considerable savings for the Treasury.
