Study on some key problems of the grid - connected main ventilator in the deep reconstruction and extension at Kongzhuang Mine
Abstract：Kongzhuang Mine put into operation after three projects of renovation and expansion, the required air volume underground need to be increased substantially. According to the measurement and analysis, the existing ventilation systems can＇ t meet the main fan ventilation＇ s needs after renovation and expansion. In this paper, based on the simulated the changes in the mine ventilation system during the transition and expansion period of mine production, the replacement of reasonable period for the existing major fan was proposed, and the optimization of a reasonable new main fan operating point when the project put into operation after the expansion. According to the field test, the main ventilation parameters and measured data underground by simulating the changes in the mine ventilation system during the transition and expansion period of mine production is very consistent. Facts have proved that it was a scientific, rational and practical solution.
