|Abstract:||With increase of energy costs and implementation of carbon tax in many countries, a cost-effective mine ventilation system has become highly desirable in underground mine operations. In this study, a novel intermittent airflow ventilation system is proposed and evaluated via simulation with the goal of reducing the energy cost whilst maintaining methane level in the mining face below the allowable level. Parametric studies are conducted to investigate the effects of various factors influencing the effectiveness and performance of this novel intermittent ventilation system, in particular the effect of intermittency period, air velocity, and application of multiple outlet nozzles with intermittent on-off flapper valves for air flow control. Significant energy savings and air handling requirements are shown to be possible through the scheme proposed. © 2014 Elsevier Ltd.|
