Abstract

In recent years, Quang Ninh coal mines are continually expanding on size and depth, the total length of the roadway each year
amounts about ten thousands meters in order to reach new production zones. The length of new roadways is usually longer, leading
to increase to the airflow demand. Ventilation is one of the main factors effecting driving progress of the roadway. The estimation of
airflow requirements is usually based on the minimum amount of airflow required at the heading during driving roadways or at the
working face, in other words, when the ventilation ductwork is at its maximum length.
Therefore, determination of maximum ventilation length of ductwork has been undertaken. This results allow the selection of a
reasonable fan to meet the ventilation requirements when driving the roadway. Also, this value is an important parameter for designing
auxiliary ventilation system that operates more efficiently on a lower cost.
