Ventilation Basic Mining Process underground COAL

The roadways underground are divided into 2 groups, those carrying fresh air into the workings ("intake airways") and those carrying used air back out ("return airways"). Adjoining intake and return airways are separated by the coal pillars or by installing "stoppings" (most commonly in the form of a wall of some kind) in any interconnecting
