矿井通风网络基础数据获取方法的研究及应用

Research and Application of Basic Data Acquisition Method for Mine Ventilation Network

本文在分析井下风压、风量、风阻三者之间关系的基础上,针对煤矿井下部分巷道分支风阻难测的问题,提出了测风求阻的方法,以矿井通风网络为例,进行了应用解算。结果表明:所有的解算风阻值的误差值范围均小于10%,满足矿井通风网络解算精度要求。

Based on the analysis of the relationship among underground air pressure,air volume and air resistance,this paper puts forward a method to measure the air resistance of some roadway branches in the coal mine.Taking the ventilation network of the coal mine as an example,the application solution is carried out.The results show that the error range of all calculated wind resistance values is less than 10%,which meets the accuracy requirements of mine ventilation network.
