There are about 40 km of galleries in the mine, most of them no longer used. The capacity of salt extraction reaches 100,000 tons per day, but demand stays far shorter than that. The number of miners working there is very low: between 5 and 10! Aeration of the galleries is ensured by ventilation systems - there are doors to open and close behind you to prevent strong draughts. The temperature inside the mine is constant: 23ºC.
