The Kłodawa Salt Mine is the only active one which exploits salt with the dry method. The mine is located just upon the salt dome, that covers only a part of the dome - that is the belt ca. 8 × 2 km. The mining production takes place within five panels in the depth interval between 300-750 m. At the stage of designing of the access excavations in the field 5 at the 750 level there was a need to solve the ventilation problem. The central shafts used as inlet and exhausting peripheral shaft have to assure a proper air exchange rate within the all galleries and chambers. Thanks to the multi-variant analysis carried out, the optimum solution could be suggested. The following problem to be solved is a muck haulage. As in the beginning the volume of the muck from access works should not be a problem, as with elongation of haulage distance the problem is getting increase, reaching the critical point with starting exploitation works. The rail transportation used underground may appeared to be not sufficient and may be it will be necessary applying another alternative solution. The problems presented in the paper are only a fragment of the greater whole, which should be faced at the stage of designing process.
