Abstract When a mine is ventilated by main drawing ventilation or combined primary and auxiliary ventilation, it is often necessary to clean the dust-laden air before its evacuation to another section. This can be effected by water spraying in the suction duct. Description of a device developed in Bulgaria, combining a mist generator (with water and compressed air supply) with a water spray unit installed downstream from it. Tests yielded a 67% reduction in dust levels; water consumption was 6l/min, air pressure 5bar and water pressure 4bar.
