It is common to find that in some mines in the coalfield of Sinifaná not exercise proper control over sealings and therefore the air can make tours of areas that do not require to be ventilated at the mine. This has a major negative impact, since often the air does not reach to operating fronts of the adequately form and makes it impossible for people can have appropriate working conditions; on the other hand it generated highly relevant economic losses related to the air injection to abandoned works. With the present study is pretend to assess how is the influence of the sealings in the behavior of the mine, in the equivalent resistance and the flows to the work fronts, this in order to establish in the case of the mine selected, which sealings can be implemented and thus optimize ventilation in the mine.
