A study on relationship of duct leakage and parameters of ducts in Quang Ninh mine
Air leakage of auxiliary ventilation ducting systems is the most common
reason for the insufficient fresh air in the working face in underground mine.
This value is important design parameter for mine auxiliary ventilation
system that operates more effectively, with lower cost.
Therefore, determination of air leakage along auxiliary ventilation ducting
systems has been examined. Also, factors which affect air leakage in the
ducting system have been investigated. Experimental data are made on 0.7
m and 1 m diameter ducts over sections of ducts installing towards the
working face in Quang Ninh mine.
