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