Analysis of Ventilation Network and Ventilation at Heading Faces.
Shigen-to-Sozai, 2000 The term of "ventilation network analysis" meant the calculation of airflow distribution in a ventilation network, that is the calculation of airflow rate through each roadway in a mine formerly. However, nowadays the meaning has expanded to mine fire simulation, thermal environment analysis in a mine, detection of abnormal roadways, optimization of ...
