针对八一煤矿转入深部开采存在的通风阻力大，供风量不足和采掘工作面温度高等问题，开展了矿井通风技术测定．结果表明矿井实际供风量为62 m3/s，低于需风量100 m3/s，供风严重不足，且通风总阻力为2712 Pa已接近矿井通风阻力上限．通风系统中进风段、用风段和回风段阻力比例为2∶1∶11．8，阻力分布不合理．根据矿井通风容易和困难时期的生产部署和配风情况，提出2方面的技术措施：一方面通过启用并联风巷、降低矿井漏风率和扩刷巷道断面等措施对矿井通风系统进行优化改造，降低矿井风阻；另一方面更换现有风机，提升通风动力．通过对通风系统优化改造，降低矿井风阻后，运用计算机对各时期进行解算分析，最终确定矿井主要通风机的型号．

Aiming at the big ventilation resistance that exists in the Bayi Coal Mine in the process of deep mining,insufficient amount of wind supply and high tunneling face temperature,this paper conducts the determination of mine ventilation technology.Results show that the mine actual quantity is 62 m3/s,lower than the cost of 100 m3/s,for a serious shortage of the wind.In addition,the total ventilation resistance is 2 712 Pa, which is close to mine ventilation resistance limit.In ventilation system into the wind,and with the wind and return air resistance ratio at 2∶1∶1 1 .8,the resistance distribution is not reasonable.According to the production deployment and the air distribution situation during the easy and the difficult period of the mine ventilation,this paper puts forward the technical measures in two aspects.On the one hand,it optimizes the mine ventilation system by enabling parallel airway,reducing air leakage rate of mine and expanding brush roadway section, etc.,so as to reduce the mine wind resistance;on the other hand,it replaces the existing fan and improves the ventilation.After optimizing the ventilation system,and reducing the mine wind resistance,it uses the computer to calculate and analyze the different periods of the main mine ventilator models,which are finally determined.
