Stress-strain State and Vibration Frequencies of Blades of the Main Mine Fan Impeller


The paper discusses geometrical characteristics and strength parameters of fan blades equipped with replaceable active part it end ended to improve the fan adjustability owing to replacement or removal of the active part, which allows the fan to maintain a wide range of ventilation modes.
