Optimization Research For Ventilation System Of No.2 Mine Of Pingdingshan Coal Mining Group

Mine ventilation system is a main fan device and underground mine ventilation network with a combination of dynamic system。Its main task to apply with the wind place the fresh air, conveying the member for breath;Diluting and emission of various toxic and harmful gases and dust;Reducing the environmental temperature of homework site ,creating a good climate condition;Especially when disaster happened according to relief needs to allocate and control airflow。So mine ventilation system are playing an important role in optimizing renovation work to improve economic efficiency,and improving the coal mine coal mining operation state。This paper comes from Ping Mei two ore mine ventilation realities through the resistance coefficient and the determination of draw the corresponding wind resistance,resistance to use mine ventilation network decoding software to optimize research of Ping Mei two ore ventilation system,Systematically analyzed the Ping Mei 2 mine ventilation network and existing problems,and use mine ventilation network decoding software worked two mining Ping Mei to such-and-such a second level reached deep mining face mining extraction, three level fan hang nets operation, three level of coal mining such-and-such stage and deep mining from various periods of ventilation system feasible scheme to optimize choice,Ultimately determine the optimal mine ventilation plan,to ensure the mine safety production has important guiding significance。...
