Study on Ventilation System Features and Ventilation Capacity Pingtu Mine

A relative stable period of the mine ventilation system was selected as a rated period.With the calculation on the required ventilation value of each mining and excavation face,chamber and standby working face in Pingtu Mine,the mine required ventilation value could be set up.According to the calculation of the mine ventilation capacity,the rational mining and excavation ratio of the Pingtu Mine determined was 1∶ 3 and the mine ventilation capacity was 1.20 million t/a.The mine ventilation capacity of 1.20 million t/a was verified with the mine ventilation power,the effective ventilation value at the required ventilation place,mine ventilation network capacity,diluted gas capacity and others.
