Research on Non-Stop Control of Switching System of Main Ventilation Fan in Coal Mine
In order to solve the phenomena such as obvious fluctuation of working face wind speed and frequent gas accumulation or over-limit problem caused by the switching process of traditional ventilator,on the basis of analyzing the current situation of main ventilator switching program,researching on the working condition point and performance curve of ventilator,we put forward the ventilator switching program without stopping and the corresponding control process,and comparing the improvement of working face wind speed and gas concentration,and achieved the ideal effect.The improvement of wind speed and gas concentration in the working face is compared,and the ideal effect is achieved.
