【Abstract】 Strong noise radiation of the axial-flow ventilation system in the mine airshaft often causes serious pollution of surroundings and interferes the normal working and life of people. In this paper, feasibility demonstration on noise control scheme was conducted according to the characteristics of the electromagnetic noise produced in the operation of the main axial-flow fan, the vibration noise produced by the fan case and the aerodynamic noise produced by the diffuser and in the light of the research results and practical experience obtained in many years’ noise control, this can be used by design persons for reference.更多还原
