Ventilation is the primary method for controlling gas and dust during longwall mining. It is not only important for controlling dust particulates, but also for maintaining permissible levels of methane. Historically, most methane-related mining disasters occurred or originated at or near the active production or development faces.
More recently, methane ignitions and explosions have occurred in mines using the longwall mining method. Therefore, designing and maintaining an efficient ventilation system for a longwall mine is of utmost importance for mine operators. However, the complex and dynamic nature of coal mine ventilation systems makes it difficult to conduct accurate and detailed field assessments.
