Abstract: Combustion of lean methane contained in the hard coal mines ventilation air raises a problem of rational use of the obtained energy. An analysis of energy demand for various desalination methods was done. The paper presents a study of possibilities to utilize energy of the ventilation air methane for desalination of mine sewage in the cogeneration system, which fully exploits the produced heat and electrical energy.
