基于矿井通风网络主导度的分支分类及实验研究

Classify Branches Based on Dominant Degree of Ventilation Networks on Mines

基于通风网络主导度理论,将通风网络各分支分为高主导分支、中主导分支和低主导分支,进而有针对性地进行分支风阻监管,且可指导调风及巷道布置。通过实验得出各分支的主导度大致和各分支的风量成正比趋势,可以通过分支风量大致预测该分支主导度情况。通过阈值的设置得出了实验模型的三类分支。

Classify the branches into high-dominant branches,medium-dominant branches and low-dominant branches based on the dominant degree of ventilation networks to manage branch resistance specifically,and which can guide air volume adjustment and tunnel arrangement.According to the experiment result that dominant degree basically proportional to air volume among branches,can predict dominant degree by air volume and draw the three kinds of branches by threshold.
