| The term of gventilation network analysish
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 network,
etc. This paper describes these analyses
first. @The heading face is one of the most important places to be ventilated in a mine. There are still some problems remained to be analyzed about the ventilation of heading faces, especially, for the discharge of flammable gases and control of respirable dust. The latter part of the paper describes the result of analysis about the heading face ventilation using an actual size model roadway, small-scaled model roadways and computational fluid dynamics. |
