A reasonable ventilation system can ensure mine safety work and economy performance for a long time. According to the actual conditions of the mine hydrology geology, climate and other conditions the design was performed.According to the character of coal seam which has high gas content, the central paratactic ventilation system in the design is adopted in initial stage (the first level ), the partition ventilation will be adopted in the later stage (even deep level ). And the main ventilation system uses extract ventilation style and gas drainage technology. This can effectively resolve the problem of the high gas content.In addition, by calculating and choosing wind amount of every place and every tunnel,according the calculation result, the main ventilating fan parameter was selected. It is helpful to establish the exploiting scheme, exploitation method, ventilating system, which are suitable to the mine, and on this basis, use the mine main ventilator and motor, the design of the ventilation system meet the requirements of the mine ventilation.
