SCATTERING DUST REMOVAL SYSTEM FOR A TUNNEL BLASTING WORK, HEIGHTENING THE EFFICIENCY ON A BLASTIC WORK BY REDUCING SCATTERING DUST USING A JETTING NOZZLE

摘要

PURPOSE: A scattering dust removal system for a tunnel blasting work is provided to minimize the discharge of scattering dust at a tunnel blasting work by making scattering dust settle by particles of water, to prevent the environmental pollution by scattering dust and to heighten the efficiency on a blasting work. CONSTITUTION: The scattering dust removal system for a tunnel blasting work contains many high-pressure pipes(5) fixed to the inside of a tunnel(1) and supplied with water, and many jetting nozzles(6) installed along the high-pressure pipes(5) to face the bottom of a tunnel(1) to fall and remove the scattering dust to the bottom of a tunnel(1) by small particles of water jetted from the jetting nozzles(6).
