Resistance Measurement and Optimized Plan of Ventilation System in Wangchao Mine
Abstract：According to the present status of the mine ventilation system in Wangchao Mine, the base point gas pressure measuring method was applied to the mine ventilation resistance measurement on the selected measured route and to calculate the mine total ventilation resistance, natural ventilation pressure, equivalence borehole and mine outer air leakage rate. The mine ventilation difficulty degree and the air leakage management status of the mine ventilation system were judged. The ventilation resistance distribution conditions of the air income section, the ventilation section and the air retuned section of the present mine ventilation system and the cause were analyzed. Based on the circumstances, taking the reduction of the mine ventilation resistance as the near target and the future mine ventilation optimized plan was provided. At present, the -400 m centralized air returning roadway was repaired. Based on the mine ventilation quantity uncharged, the mine ventilation resistance was reduced by over 260 Pa.
