Abstract: In order to ensure the safety and reliability of the ventilation system of Nan'aosi Coal Industry Co., Ltd., this paper
calculated and analyzed the indexes of the operation safety of the ventilator, the use of the air at the air point, the rationality of
the ventilation system, the supply-demand ratio of the air volume in the coal mine, the operation effect of the counter air system,
the operation reliability of the local ventilator, the reliability of the ventilation equipment and the rationality of the air pressure in
the coal mine. According to the calculation, the safety level of the ventilation system of Nan'aosi Coal Industry Co., Ltd. is 87.9,
and the ventilation system is reasonable.
