Abstract
This article explains how to reduce respirable dust in hard rock tunnels during excavation by tunnel boring machines (TBMs). When dust levels are too high, the dust source must be pinpointed and the ventilation and dust collection systems must be checked. If the ventilation and dust collection systems are working properly, then the water sprays or conveyor dust controls must be upgraded. The management of other air contaminants has been covered elsewhere.
