Optimization Design and Application Analysis of Resistance and Pressure Reduction in Ventilation System
There is a problem of high wind resistance in the mine ventilation system,which leads to a high negative pressure inside the mine,seriously affecting production safety and efficiency.By clarifying the methods and calculation methods for measuring wind resistance in ventilation systems,mastering the factors affecting wind resistance,the ventilation system can be optimized and designed to achieve the goal of reducing resistance and pressure.The optimization design mainly includes three aspects,namely reducing power consumption through natural ventilation,adjusting the frequency of the main ventilation fan,and adding return air measure shafts.Finally,simulation application effect analysis was conducted,and the results showed that the optimized mine total wind resistance decreased by 350.57 Pa,negative pressure decreased by 440 Pa,and the resistance and pressure reduction effect was significant.
