摘 要:为了能够准确获取南屯煤矿通风阻力数据,采用精密气压计逐点测定法,对南屯煤矿中央风井和白马河风井的通风阻力进行测定。通过分析数据,得出中央风井通风系统通风阻力为1238.8 Pa,风阻为0.14 N·s^(2)/m^(8),等积孔为3.17 m^(2);白马河风井通风系统的通风阻力为1390.1 Pa,白马河风井通风系统风阻为0.29 N·s^(2)/m^(8),等积孔为2.22 m^(2),2个风井的通风难易程度均为容易通风。经计算,测定误差均小于5%,满足精度要求,测定数据能够为通风系统阻力优化提供精确数据支持。In order to accurately obtain the ventilation resistance data of Nantun Coal mine,the ventilation resistance of the central shaft and the Baima River shaft of Nantun Coal mine is measured by the precision barometer point-by-point method.Through analyzing and sorting the data,it is concluded that the ventilation resistance of the ventilation system of the central air shaft is 1238.8Pa,the wind resistance is 0.14 N·s^(2)/m^(8),and the equal area hole is 3.17m^(2).The ventilation resistance of Baima River ventilation system is 1390.1Pa,the ventilation resistance of Baima River ventilation system is 0.29 N·s^(2)/m^(8),and the equal accumulation hole is 2.22m^(2).The ventilation difficulty of the two ventilation shafts is easy ventilation.Through calculation,the measurement errors are all less than 5%,which meets the accuracy requirements.The measured data can provide accurate data support for the resistance optimization of ventilation system.
