Measurement of the Performance and Safety Optimisation of Main Ventilation Fans in Mines
In order to solve the problem that the ventilation system fails to meet the provisions of Ventilation Technical Conditions for Coal Mine Shaft Mining with the advancement of the working face,based on the determination of the ventilation resistance,ventilation volume and performance parameters of the ventilation fan in combination with the practical production of the working face,it is possible to grasp the direction of the ventilation system's subsequent optimisation and reconstruction,and to make a comprehensive comparison of the three optimisation and reconstruction schemes in terms of ventilation effect,safety and construction volume,and finally to arrive at the optimal reconstruction scheme.The three optimised solutions were compared and the optimal transformation plan was finally obtained.
