Ventilation System Resistance Measurement and Ventilation Plan Optimization of East Mine Ventilation Shaft in No. 8 Mine of Pingmei
Abstract：According to the negative pressure too high existed in the main ventilator of Mine East Ventilation Shaft in No. 8 Mine of Ping-met, a barometer hase point method was applied to the ventilation resistance measurement of the ventilation system. The measured results showed that the total resistance of mine ventilation in Mine East Ventilation Shaft was 3 077 Pa, over 2 940 Pa stipulated in Coal Mine Ventilation Technical Condition. The ventilation resistances at the air income section and the air retuning section were too high. The main causes were the ventilation route too long, some gateway cross section too small, ventilation distribution irrational. In combination with the long term mining plan, an optimized plan of the ventilation system in the Mine East Ventilation Shaft was provided. The MVSS software was applied to the ventilation network calculation of the optimized plan. With the comprehensive comparison, No. 2 plan was finally ap-plied to the optimization of the ventilation system in Mine East Ventilation Shaft.
