Abstract

PURPOSE: To eliminate occurrence of fine droplets by providing an device for heating or dehumidifying exhaust gas from a cave passage in the vicinity of the air outlet of the passage.
CONSTITUTION: A cave passage ventilation hole 3 is perforated from the ground GL to the cave passage in the vicinity of the outlet of the atmospheric air 1 of the passage 2 laid with cables or the like with a heater or dehumidifier arranged thereat. The exhaust air from the passage 2 is heated or dehumidified by the heater or dehumidifier 4 and then made contact with the atmospheric air 1. Thus, its relative humidity becomes low to thereby eliminate the occurrence of fine droplets in mist state in the air thus exhausted.
