In order to realize the reliable and stable operation of the ventilation system of Wangzhuang coal mine, this thesis studies the operation of the ventilation system after the operation of the Beili wind well in Wangzhuang coal mine. The first is to conduct a comprehensive analysis of the existing ventilation system of Wangzhuang coal mine; The design and simulation of the independent ventilation scheme for the ventilation system of the new district; the third simulation analysis of the ventilation system during the disaster. Based on the ventilation parameters test of the ventilation system after the operation of the Beili wind well in Wangzhuang coal mine, the ventilation management ination system of Wangzhuang coal mine was established to analyze the current situation of the ventilation system the resistance distribution of the three zones of the Beili return air well, Pressure distribution, effective air volume rate, etc., found that there are problems in the two recovery areas of the new district 71 and 81 sharing the return air duct. In order to realize the independent ventilation of the mining area, the system adjustment scheme was designed, and the simulation was carried out step by step. Combined with the influence of the fan parameters of the main operation of the new area and the air volume change of the mining area, the feasibility of each adjustment measure was verified. The adjustment plan for new structures at the return air ducts and the main return airways of the two working faces of 8106 and 7110 was determined, and the goal of independent district ventilation was realized. Finally, in order to improve the ability of the ventilation system of the new district of Wangzhuang coal mine to cope with the catastrophic after the new wind tunnel was put into operation, the stall analysis, anti-wind scheme design and damper failure simulation of the two return air blowers in the new district 540 and Beili were simulated to simulate the disaster. During the period of changes in the ventilation system, corresponding countermeasures were proposed. By studying the changes in the ventilation system during the disaster period, the mine emergency response capability was improved, which provided a basis for the ulation of the emergency plan and laid a solid foundation for the safe production of the mine. 万方数据 III There are 20 Figure s, 29 Table s and 54 references in this Thesis.
