Taking rock roadway work of Wajinwan Company as the study target, the study is aimed to tackle the issue of undesirable ventilation from traditional forced pressure ventilation approach due to swirl effect by applying far-pressing-near-absorption ventilation system in mine rock roadway excavation and using Fluent software to build far-pressing-near-absorption ventilation model to optimize the parameters of ventilation system. One-site observation and analysis of measured data shows that less dust concentration than that without negative pressure hairdryer and the application has borne positive effects.
