After connecting the main, vice, air shaft of BaiXiangshan iron mine, has high formation temperature, ventilation of long distance, multi level construction at the same time, the insufifciency of air supply, ventilation system instability and other problems. Through constructing the reasonable ventilation facilities, effectively increasing resistance to adjust the air distribution, selecting and installing the high power fan, formed a reasonable and stable full wind press mechanical ventilation system, which increase the mining, tunneling working face and the chamber for air volume, reduce the downhole temperature, improve the working environment, and provide technical support for the safety in production of coal mine.
