ABSTRACT

Mine ventilation has a key role to improving underground working conditions.
Ventilation is required to clear dust, gas and toxic fumes from blasting and removing
exhaust fumes from diesel equipments and also required for cooling the workplace for
miners in deep hot mines. Ventilation systems need to take many possible modern
mining scenarios into account, and costly infrastructure is needed to serve future
ventilation and cooling requirements. To enable the practical and economical design of
mine ventilation systems, effective and modern computer tools are required to simulate
mine ventilation networks.

This paper examines the design of a ventilation system, which will provide the
necessary control of mine atmosphere within Tabas underground coal mine in Iran. The
ventilation design based on the “critical velocity” has been done by computer modeling
method. Alternative configurations of the underground space are simulated by VUMA®
mine ventilation software. These alternatives affect the direction and velocity of the
airflow and, consequently, the air quantity and the fan power required, in order to
achieve to the secure workplaces.
