Abstract: This paper studied the low utilization rate of air volume in the ventilation system of Dayu Coal Industry Co., Ltd.,
established a new evaluation system by analyzing the factors affecting the performance of the ventilation system. At the same time,
it analyzed the ventilation environment and the rationality of network of the ventilation system, and used several basic theories of
air flow to scientifically and objectively reflect the performance of the ventilation system. On the basis of the evaluation system,
the factors that affect the performance of the system were defined. Through the use of two schemes of ventilation optimization in
driving roadway and reduction of ventilation resistance, the air utilization rate of the system was improved. The application of the
optimization scheme can make the air supply stable and meet the mine production requirements.
