Abstract– A mine ventilation system is an important component of an underground mining system. It provides a sufficient quantity of air to maintain a suitable working environment. Therefore, the mine ventilation system should be kept at a highly reliable level and also be maintained at a very reliable level during the whole service time of the coal mine. However, in reality, failures of a mine ...

Ventilation conditions in mines must be monitored to ensure safe and healthy conditions. However, the multiplicity of ventilation branches and equipment make it impractical to automate measurement of parameters all over a mine. It is more practical to monitor a few critical measurements that are fully reliable and extrapolate to ‘predict’ remaining conditions using ventilation network software....

It is necessary to obtain a fundamental understanding of the goaf gas flow patterns in longwall mine in order to develop optimum goaf gas drainage and spontaneous combustion (sponcom) management strategies. The best ventilation layout for a longwall underground mine should assist in goaf gas drainage and further reduce the risk of sponcom in the goaf. Further, in the longwall panel, regulators ...

Controlled recirculation has been used in the metal/nonmetal mining industry for energy savings when heating and cooling air, in undersea mining and for increasing airflow to mining areas. For safe and effective use of controlled district recirculation, adequate airflow to dilute contaminants must exist prior to implementation, ventilation circuit parameters must be accurately quantified, venti...
